The influence of drainage canal network on groundwater regime in the catchment

Abstract

Since the area of the southeastern Srem was extremely endangered by excess water, several drainage water systems had to be built. In order to define the efficiency of the drainage systems constructed in the fifties of the twentieth century, field investigations of the groundwater regime in southeastern Srem were initiated. The very first results have indicated that the groundwater regime in southeastern Srem is very complex. Apart from the influence of the constructed drainage systems, the regime of groundwater depends upon several natural (precipitation, evapotranspiration, hydraulic and hydrological) characteristics of the Sava river, which represent the boundary of investigated area and anthropogenic factors. This paper present the results of analyses of the influence of drainage canal network on groundwater regimes in the catchments of Galovica and Petrac, in southeastern Srem.

Izuzetna ugroženost područja jugoistočnog Srema suvišnim vodama uslovila je izgradnju nekoliko velikih sistema za odvodnjavanje. U cilju utvrđivanja efikasnosti izgrađene kanalske mreže pedesetih godina dvadesetog veka započeta su istraživanja režima podzemnih voda u jugoistočnom Sremu. Već tada je konstatovano da je režim podzemnih voda u jugoistočnom Sremu veoma složen. Osim izgrađene kanalske mreža za odvodnjavanje, na karakteristike podzemnih voda utiče nekoliko prirodnih (padavine, evapotranspiracija, hidrološko-hidrauličke karakteristike reke Save koja ograničava ovo područje) i antropogenih faktora. U ovom radu su prikazani rezultati analize uticaja kanalske mreže za odvodnjavanje na režim podzemnih voda u slivnim područjima Galovica i Petrac u jugoistočnom Sremu.
