Quantitative and modelling evaluation of the hydrologic function in the Greaca landscape

Abstract

The hydrologic function has been evaluated for the Greaca area, component of the Lower Danube Wetlands System. The evaluation was comparative for two periods of time (before and after the Danube damwas build). The antropic impact on this area is discussed analyzing the total volume of water retained by this area, for the two periods of time. We used SWAT to evaluate the degree of basin fragmentation and, based on the results obtained, it is discussed the human role in the fragmentation of hydrologic basins.
