Summary: Simulation of complex hydrological systems operation for floodrouting is performed using a mathematical model based on completehydrodynamic equations. The analysis includes both the channelflow and the raifall-runoff and is based on meteorological data.Differential equations are numerically integrated employing thefinite element method. The model is organized in two moduls: ahydrodynamic modul for the channel, with a parallel computerizedprocess. A great number of equations are solved efficiently byusing an appropriate algorithm (banded matrices or frontalmethod). Large domains require a sutable organization of inputparameters which necessitates developing a specific methodology.

Keywords: Hydrologic system, Mathematical model, Flood routing, Channel flow, Rainfall-runoff, System operation
