Summary: The ussefulness of studying the morphological evolution of
recentrelief and karstification is demonstrated by threemorphologically
different karst terrains. Using the results ofthese studies, as well as
earlier geological and hydrogeologicalmapping, the knowledge about
constructioon feasibilities ofseveral storage basins has been considerably
improved. It hasalso contributed to bringing about very successful intakes
of karst groundwater.
Keywords: Karst, recent karstification, karst hydrogeology, storage bottom leakage, groundwater intakes.

Summary: The paper describes the problem of establishing
sanitaryprotection zones around water sources in karst regions, citing asan
example the principal postulates of the Draft Propposal of Amendments to
Regulations on Protective Measures and Conditionsfor Establising Sanitaryy
Protection Zones of Potable WaterSources. The paper proposes the number of
sanitaryy protection zones,criteria for delimiting general zones, and
suggests thathydrogeological investigation works are necessary.
Keywords: potable water, water source, protection zone,zoning, sanitary protection,hydrological investigation works.

Summary: The intermittent karst spring Slanac east of the town of
Trogir is a unique karst phenomenon by its appearance at an altitude of 30
m above sea level. This is a consequence of the areal hydrogeology and the
development karstification and karst groundwater flow paths from the most
recent glaciation to the present. There are at least three factors
controlling the discharge of brackish water at such altitudes during the
highest groundwater tides: (a) a considerably greater permeability of
calcareous rocks lying below the present sea level in comparison to the
permeability of the upper parts, (b) the presence of almost pure sea water
upstream of a hanging hydrogeological barrier at the spring site at the end
of a dry season, (c) ever higher hydraulic resistance to groundwater flow
below the hanging hydrogeological barrier due to ever longer siphonal flows
and their gradual colmatation.

Summary: The Boljkovac spring is 3500 m far from the Adriatic Sea
and 3.25above sea level. Its drainage area is situated in a low
coastalkarst terrain. The basic characterstic of the spring is that
itswater is fresh during the dry season (having the rate ofdischarge not
surpassing 10 l/s) and slightly brachish in the wetseason. This suggested
the existence of concentrated ground-waterflows on altitudes lower than sea
level. After a test pumping,the pumping construction was built by which
about ten timesgreater quantity of water pumped out during the dry season
thanit used to discharge earlier and pumped water saqlinity did notincrease
substantially.
Keywords: Karst, overexploatation of a Karst spring.

Summary: Under recent geomorphological processes in coastal karst
terrainsone may understand the karstification that has taken place sincethe
last glacial until recent, influenced by sea-levell rise infunction of
erosional base for karst ground-water. This continoussea-level rise, still
active, is related to development of recentcoastal brackish springs and
vruljas. During the recent sea-levelrise location of springs and vruljas
has been changing andconsequently quiet many underground and surficial
karst featureshave developed. Some of these karst phenomena are even 10 km
awayfrom the present sea coast.
Keywords: karst,recent coastal karstification, coastal brackish springs,vrulja.

Summary: The possibilities of disposal of matter hazardous to sea
and water in the inland part of Dalmatia are very limited from the
hydrogeologigical aspect. For this reason the majority of dump sites is in
inadequate locations. The causes for the said limitation are many.The
majority of this karst terrain falls into the protected areas with
hig-yield srpings and potable water well fields, and they are prohibited
for waste disposal. The majority of the remaining terrain belongs go the
catchments og the closed bays and estauries of the rivers, which are the
waters of a very sensitive ecosystem. Deterioration in water quality in
these predominanlty protected areas (e.g. Mali Ston and Kaštela bays, the
Krka River estuary) might cause unpredictable adverse effects on the flora
and fauna in the reion. When the active and potential tourist centers are
also excluded, Dalmatia is left with a narrow intermittent belt by the sea
shore for waste disposal. With respect to the territorial sea protection,
this remaining terrain is goruped in three categories, depending on wheter
it is made of permeable, less permeable or poorly permeable rocks. For each
category, the macro locations offering optimum natural conditions for waste
disposa are proposed.
