Abstract

The main research goal was to assess the potential impact of the future Multipurpose Danube-Sava Canal (MDSC) on the groundwater level in agricultural soils spread in the immediate hinterland on both sides of the canal, in the lower part of its course. To observe the impact of the canal envisaged by the project on potential changes of the groundwater level, a series of piezometer boreholes were drilled along the canal course. Geological and hydropedological characteristics of the covering layer were determined in all boreholes and groundwater levels were continually monitored over a six-year period (2001 to 2006). The obtained indicators were used to design a numerical model of groundwater flow. The model indicated that MDSC would primarily have a draining role in the largest part of the studied area. Only in a smaller part of the studied area with the lowest terrain elevation will the MDSC feed adjacent agricultural soils with water.
