| Zusammenfassung |
| Determination of the catchment area is the starting point in most
hydrological analyses. It serves as a basis for many hydrological and water
resources management calculations. The catchment boundaries and areas in
karst regions are often fragmented and not accurately known. They can change
over time due to natural and anthropogenic causes. Natural and man-made
processes cause changes of catchment area on different time and space
scales. Human intervention, especially construction of dams and reservoirs,
as well as interbasin water transfer through long tunnels and pipelines can
introduce instantaneous, definite and hazardous change. This paper presents
seven examples of natural and anthropogenic factors which influenced changes
of catchment area in the Dinaric karst: 1) Closing of the Obod Estavelle in
the Fatniceko polje; 2) Operation of the Zakucac hydroelectric power plant on
the Cetina River; 3) Problems caused by Salakovac Reservoir; 4) Catastrophic
flooding in the Cetinje Polje; 5) Regulation and canalization of the
Trebišnjica River; 6) Building of the underground hydroelectric power
plant Ombla; 7) An earthquake in Southern Croatia and Western Herzegovina. |
