Summary: The Estern coast of Adriatic Sea is considered to be one of
themost developed coast i Europa. This development is increased bythe chain
of many islands. The archipelago consists of 558 isletsand 69 islands, and
more than 400 rock-reefs.
The islands are mainly built of limestones and dolomites.Eruptive rocks are
rarely present.
The morfology of islands, geological composition and geologicalstructure,
the size and form of the island have the effect on theformation of the
subterranean waters and their quantity. Thesurface lakes, captive
subterrenean waters in wells and galleriesare used for watersuplly, while
recently the watersupply from themainland is introduced. On the smaller
islands the zainfale eatergathered in cisterus is used for watersupply.

Summary: Rijeka harbour cannot accept all the cargo gravitating to
it.Complex investigations are necessary for building the harbour andup now
several locations have been taken into consideratio.Factors which influence
the choice of the location are of varioussignificance.
All the natural conditions of the terrain have been taken intoconsideration
forthe area of Bakarac, to find the projectsolutions which will enable the
optimal use of the area foreconomic building and exploiting the harbour
objekts.
The developed relief and the depth of sea are limited factors forthe
building of harbour. The necessary areas could bee optainedby raising the
level by shooting material on the sea bottom andcutting of the continental
parts of the terrain.
The rocks composed of limestones are stable in the naturalconditions and
under the influence of engineering works. They arefavourable for embankment
material under the sea level. Contraryto that the flysch sediments present
unsatisfactory of the rockmaterial concerning the stability and usage. The
geologicalstructure and the tectonics as well as the complex works on
theplace of the furure harbour make the engineering workscomplicated.

Summary: The shortage of drinkig water will present, in near future,
one of the major problems in water supply. Water pollution in some
locations has already reached the tolerance limits, and to stop the
deterioration trend of water quality it is necessary to establish sanitary
protection zones, i.e. to find the principles of effective protection of
ground water and sources. In the Republic of Croatia, the protection id
defined by the Regulations on Protective Measures and Conditions for
Definig of Sanitary Zones for Protection of Drinkig Water (NN 22/1986). The
Regulations are based on empirical determining of protection zones,
defining three different zones. This way of solving the issue causes
difficulties, in particular in protection of sources in rocks of
intergranular porosity and karst sources. The analysis of demonstrated
solutions of protections, and discussion of their possible drawbacks and
problems that might occur if the Regulations were fully respected,
discovers the major defects of the Regulations and proposes the principles
of groundwater and water sources protection. Groundwater and sources may be
effectively protected by measures organized and implemented on three
levels. The first level would encompass protection of registerred and
categorised groundwater resources on the territory of the entire Republic
of Croatia. The second level would be inplemented by protection zones
around individula sources, and their sizes would be determined on a
case-to-case basis, depending on actual hydrogeological conditions and
local conditions. The third level would be include a number of measures
regarding the design and constructions of water intake facilities.

Summary: Protection of the groundwater quality is a very complex
problem. t does not refer to groundwater only, but also to surface
water and soil, and not only to quality but to quantity as well. Protection
of groundwater quality imposes restrictions both to the society and to the
individual; in other words, the socio-economical relations are relevant.
With respect to the importance of groundwater in water supply, solutions
for its protection must be found as soon as possible. The solutions offered
by the protection system should be practical, but also realistic.
Protection, including defining of protection zones, was subject to
considerable changes in the past; however, two basic approaches have
remained. One is based on empirical determining of protection zone sizes,
and the social and economic circumstances in various countries it is
difficult to compare their protection systems. The paper gives a tentative
review of protection systems, emphasizing the criteria for determining of
the sizes of protection zones and limitation of activities within these
zones.

Summary: The delimination of a drainage area together with the
accurate estimation of it's surface area represents an important problem in
dealing with karst springs. Water gushing from the fractured karst
identifies the Gradole spring as a typical karst well of the rising type.
The spring never runs dry, the ratio of minimal and maximal discharge being
1:15 to 1:20 or more. The surface of drainage area and its spatial
distribution have been defined on the basis of geological data; tectonics,
morphology, photogeological interpretation, hydrogeological characteristics
of the rocks, the karst morphology (sinkholes, pits) and underground water
tracing data. The drainage area is predominantly composed of carbonate
rocks, mainly limestone, but there is also a lesser flysch component -
marls and sandstones. The karst area is without any surface waterflows, in
contrast to flysch area where a hydrographic network of intermittent
surface streams is developed. There are no real barries to undreground flow
within the carbonate rocks. Nevertheless, the direction of flow is
influenced by structural elements, the position of layers, the appearance
of rocks - thin layers, shows of some less permeable rocks - dolomites,
fissured and marly limestones. The confirmation of an underground
connection of Čiže swallow hole with the Gradole spring shows the
possibility of supplementing low waters through the swallow holes from
Butoniga accumulation lake.

Summary: The water supplies of Požega valley according to the
position of natural occurrence are confined within the closed watershed of
the region. The water regime is characterized by the large quantity of
water within the rainy, flood periods and on the contrary by the lack of
water within the periods of dryness. The regional development program
favors the regulation of surface waters by planned accumulations and dams
while the so far established and potential groundwater supplies are
neglecte. The real potential of groundwater use is far above the recent
one. The groundwater supplies are confined within the mountain,
mountain-slope and alluvial aquifers and according to its position,
quantity and quality of water are particularly suitable for the development
of water supply system of Požega. The explorations of until recenty unknown
mountain-slope aquifer within the alluvial fans along the Mt.Papuk slope
suggest the existence of groundwater supplies which are comparable with
even those already planned by surface accumulations.

Summary: Hydrogeological relations within the Sv. Ivan spring
watershed in Istria caused a specific machanism of groundwater storage and
discharge. A considerable storage of groundwater has been realized through
a structural fabric of deposits containing Paleogene and Creataceous
karstified limestones covered with Eocene flysch precisely in the parts of
the catchment with the lowest hipsometrical elevation. The formed marginal
conditions and high permeability of karst aquifer enable comparatively high
minimum yield of the Sv. Ivan spring and result in a comparatively low
minimum/maximum yield ratio. The crucial effect on maximum yield of the Sv.
Ivan spring regime is the one of the intermittent spring of Tombazin which
is actually the groundwater overflow from the karst aquifer at extreme
water tables.

Summary: Quaternary deposits in wide area of Drava valley build's
aquifer with large amount of groundwater. Western part consists of sand and
gravel layers, while eastern part has predominantly uniform sand mixed with
layers of silt and clay. Natural replenishment of groundwater from
precipitation in the region is higher then groundwater use for public water
supply, but local distribution network and available groundwater budget in
some eastern parts is such that planned necessity exeeded local natural
groundwater recharge. In central and western parts of the region exist
surplus of availlable groundwater budget what can be intersting for public
water supply of neighboring deficit part and agricultural purposes.
Specially is important convenient relationship between rechargeable and
deposited store of groundwater and possibility of induced infiltration.

Summary: A current research project, based on the electro-hydraulic
analogy, is shorty described. The basic geoelectric parametar, resistivity,
of loose sediments saturated with groundwater is used to evaluate
approximate values of important geohydraulic parametars. This method cuts
exploration costs considerably and can be applied to solving several water
management problems related to horizontal and vertical groundwater flow. It
refers particularly to groundwater quality protection in areas of developed
agriculture. Ten research pilot areas have been established in the plains
of northern Croatia and project results in five of them are briefly
discussed.

Summary: The groundwater exploration within the drainage basin of
Drava river in Croatia is considerably increased. The main source for
public water supply is the aquifer formatted in heterogeneous quaternary
deposits up to 300 m thick. This is spread over the whole area of wide
Drava valley with genty sloping toword east. The western parts consist of
gravel and send with high permeability in contrast to eastern parts made up
predominantly of uniform sands alternated with clay and silt layers. The
infiltration from precipitation is the main source of natural recharge.
However, in condition of intensive groundwater extraction the inducing
recharge from Drava river flow could be realizable. Because of great
groundwater reservoir potential the aquifer has overall regionall
significance. Nevertheless, there are some locations within the region
where consumer demands exceed local groundwater resources. The paper
presents groundwater analysis experience in Croatia part of Drava valley
with main characteristics of aquifer.

Summary: In the Slavonska Podravina region, including the towns of
Slatina, Orahovica, Donji Miholjac and Našice, there are various
well-fields used in minicipal water supply systems. Based on the conducted
analyses of specific characteristics of tapping and potential well fields
and alternative scenarious for development of water distribution systems it
has been concluded that the natural conditions and the actual developments
in resolving of water supply issues lead to interconnecting of these
systems. such circumstances directly affect considerations related to
developmental plans and design activities for individual sections of the
distribution system. The framework of this regional water supply system
shall be formed by adequate conncting of the three peripheral well fields.
These are Medinci by Slatina on the west, Velimirovac by Našiceon the east,
and Donji Miholjac in the north.

POTABLE-WATER SOURCES IN INTERGRANULAR POROSITY ROCKS AND KARST

Summary: The protection of both surficial and groundwaters is part
of complete problems of protection and preservation of environment. The
pollution of surface waters is well known to be inevitable conswquence of
industrialization and urbanization, especially in highly developed
countries. The pollution of groundwaters is seldomly occures, but it's
effects become visible only many years after the intrusion of pollutants
into subsurface actually happened. The dangers of pollution can originate
from different sources. These sources are the processes of infiltration of
waste industrial and municipal waters of towns and settlements, the
agricultural waste waters, contaminated surficial waterflows and other
water accumlations, flushing of roads and from landfills. The lack of
quality of potable water will be one of the big problems in near future.
The impurities of water are somewhere already close to the bordres of
tolerance. To stop the trend of lowering of quality of these waters it is
inevitable to establish the zones of sanitary protection, meaning to find
out the principles of efficient protection of groundwaters and water
sources. The hydrogeological properties of porous media with fracture and
intergranular porosity are described, as well as basic theories of
groundflow and the transport of pollutant through the media mentioned. The
migration of the pollutant through and down to the water-satureted porous
medium is a very complicated process, much dependable upon hydrogeological
properties of medium, the condition of groundwater and groundwater flow,
and upon the reaction processes between the pollutant, groundwater and the
minerals making the particles of water-bearing layers. Furthermore, the
migration of pollutant is very much depending on the type of pollutant,
namely it's chemical composition and physical properties, the hydrophilic
and hydrophobic pollutants being differentiated in that sense.
The findings of the type of potential pollutants and their migration in the
subsurface should have been the basis for positioning of future water
sources, namely for planing of their protection.The two basic principles of
establishing the protection zones are applied in practice. One is based on
empirical dimensioning of zones and conditioning of behavior therein, and
another is based on studies of behavior of each pollutant separately and
calculation of minimal distance between each source of contamination and
the water source. The first principle mentioned is applied in most European
countries, and the second one in Great Britain. The protection og
groundwaters in tke Republic of Croatia is regulated by "The Protection
Measures and Conditions of Establishing of Sanitary Protection Zones of
Potable Water springs Act" (NN No. 22/1986). The Act is based on empirical
dimensioning of protection zones, the three zones being foreseen
altogether. The difficulties, meaning the problems arising from the
planning of protection of potable water sources in that way are discussed
in this paper. The way of establishing the protection zones in
potable-water supply areas in the intergranular porosity rocks, the karst
springs and the surface accumulations is illustrated. The potable water
supply area in intergranular porosity rocks are subdivided in two groups,
the ones with the open aquifer and the ones with semi-confined ir confined
aquifer. Taking into account that the Act is based on the principles of
ideal protection, not considering the differences of natural conditiuon and
the reality of economic development of area surrounding the water sources,
it's standard provisious are not implementable, the solution being regulrly
searched through the means of transitional provision which, in fact, allows
exceptions. The dimensioning of protection zones is shown on examples of
the Zagreb potable-water supply areas of Sašnjak and Šibice, the
potable-water supply area Kanovci near Vinkovci, and the Osijek
potable-water supply area Vinogradi. The protection of karst springs
presents a special problems because it is substantially different from the
protection of groundwater in intergranular porosity rocks. The Act failed
to treat the karst area separately. Each karst spring has it's
specificities, the examples of the springs Bulaž, Sv. Ivan and Gradole are
showing how should the establishing of protection zones, be adjusted to
actual hydrogeological conditions within the drainage basin and
substantiated with the results of detailed investigations. The Butoniga
accumulation is the example of protection of surface waters. The analysis
of presented solutions of water sources protection in the intergranular
porosity rocks and in the karst, and discussion of their eventual lacks and
problems that could be arising from the complete honoring of the Act, are
showing the Act's main shortages and suggesting the principles of
protection of groundwater and water sources. The groundwater and water and
water sources could be efficienty procted with the protective measures
organized and implemented on three levels. The first level would encompass
the protection of evidented and categorized resources of groundwater on the
complete territory of Repubvlic of Croatia. The second level of protection
would be realised by the protection zones of all water sources, dimensioned
separately for each water source, in accordance to the specific
hydrological and actual field conditions. The third level of protection
would encompass the group of measures connected to the planning and
realisation ofv water-cachment facilities.

Title: HYDROGEOLOGICAL INTERPRETATION OF ENVIRONMENTAL IMPACT ON
KARSTIC AQUIFERS OF CENTRAL ISTRIA
- Authors:
- Vazdar, Tatjana (204901)
- Urumović, Kosta (51212)
Language: hrvatski
Summary: The Central Istria represents the marginal part of the
Croatian karst region characterized by specific environmental imapct on
aquifers formation and their water quality. Geological framework,
morphology of terrain, high level of precipitation in hinterland together
with high level of karstification, enable deep circulation of underground
waters thus making conditions for contemporaneous runoff of different
magnitude on a bigger number of springs. The distribution of water-budget
is dependable on undreground water level and precipitation regime. In such
conditions substantial changes of the regional hydraulical relations of
groundwater system become prominent leading to the occasional catchment
area overlap so that areas considerably exeed the relations established by
the sink-hole tracings. This speaks im favour of environmental impact on
the karstic aquifers that has temporally longer influence and is affecting
the larger area, and that in real conditions neighbouring geological,
hydrological and hydrogeological investigations become especially important
in the study and monitoring of quality of underground water.
Keywords: karstic aquifers, water-budget, catchment area, environmental impact, central Istria

Title: HYDROGEOLOGICAL ASPECTS OF USE AND VULNERABILITY OF
GROUNDWATER IN THE NORTHEREN CROATIAN

Summary: Northern or Panonian Croatia has relatively suitable
hydrometorological and hydrogeological conditions for groundwater use. In
the largest part of this region, the precipitation infiltration is so high
that it enables - if only its plains are considered - four to six times
greater groundwater extraction than the actual one in the whole region. It
is necessary to mention also that 96% of the actual public water supply of
this region is based on groundwater. Concerning its hydrogeological
conditions, this entire region formsone complex hydrogeological region -
the Northern Croatian or Panonian hydrogeological region. Within it, three
hydrogeological provinces are separated:low mountain massifs, hilly margin
of mountain massifs and plains. Groundwater quality is, at least now,
mainly suitable for public water supply and irrigation. However, the
groundwater protection has become and will be ever more complex in large
plains due to a high present and potential concentration of urban,
industrial, traffic and agriculture sources of pollution. Besides,
geohydraulic connection between the highest yielding aquifer and already
very polluted main rivers are extremely high.
Keywords: hydrogeology of porous media, groundwater use, aquifer vulnerability

Title: THE REHABILITATION OF WELL DEMAGED BY IRON BACTERIA ON
OSIJEK WATER WELL AREA
- Authors:
- Hlevnjak, Branko (169421)

Language: hrvatski
Summary: Within the alluvial aquifers of the Drava and the Danube
river drainage system the anoxic water environments are very often,
characterized by higher content of iron and manganese dissolved in water.
these conditions are suitable for a development of iron bacteria at wells.
The growing rate of bacteria is particulary high on filters due to the
higher content of oxigene and continuous inflow of iron (manganese).
Consequently, the filtres get coated with threadlike slimes of iron
hydroxide. The bacteria precipitate iron from the solution, and store it as
iron hydroxide inside or outside their sticly bodies. Rapid grow of the
bacteria create a voluminous material plugging the screen openings and
surrounding area, gravel pack, sometimes even the aquifer cousing the
reduction of specific capacitty. The rehabilitation of in this way demanged
well has been performed on one well of Osijek water well area.
Keywords: underground water, well, iron bacteria, well rahabilitation

Title: ENVIRINMENTAL IMPACT ON KARSTIC AQUIFERS IN ISTRIA IN
WESTERN CROATIA

Summary: On the Istria Peninsula in western Croatia karstic aquifers
are developed that are suitable for study of sustainable development on one
side of this touristically developed area, and on the other side of inland
that has important agricultural supply. The area has high demand for
water-supply during the summer/dry season. The geological framework,
morphology of terrain, high precipitation in hinterland together with well
developed karstification that creates deep circulation of underground water
and important migrations of watersheds of individual springs. The study of
the quality of underground water and monitoring of it during the period of
low-water level becomes especially important for monitoring of
envirinmental impact on underground waters in real contions. The most
realistic data will probably be obtained from overpumping conditions.
Favorable conditions for this procedure exist because of the extensive
hydraulic connection of springs with caverns that reach the depth of
approximately 50m below the sea-level. This research could contribute to
the definition of scales in the exploration of karstic aquifers.
