The concept of the irrigation system between Rivers Fekete-Körös - Fehér-Körös

Abstract

The recent climate changes require developing of the water resource utilities. The Nagydelta area bounded by the Rivers Fekete-Körös and Fehér-Körös represents favourable conditions for irrigated agriculture activities because on one hand the Fekete-Körös provides the necessary water resources, on the other hand, the terrain conditions are favourable for irrigated land use, the existing open canal drainage system provides the necessary water conveyance capacities. The water supply could be provided for the entire Nagydelta by the increased capacities of Gelvácsi main and the Gelvácsi 9 affluent canals, and by the gravitational or pump-based water withdraw planned on the left bank at 19+900 levee km. However, based on some reasonable considerations, the new ridge canal would provide water only for the Nagydelta area stretching to the Gyulavári main canal. The rest of the area could be supplied by water taken from the dammed River Fehér-Körös via Kisdelta outlet. Gravitational water withdraw could only made in case of constructing a damming facility. The later one could be raised in the technically easiest way on the Romanian reach of the Fekete-Körös in the cutoff between 19.15-20,05 river fkm. A bit more complicated but it is possible to build the dam on the Hungarian reach between 15.48-15.69 fkm, downstream of water withdraw Morgófoki. Wherever the dam would be raised it had cross-border effects. The water withdraw from the rivet channel could be of 2.0 m³/s and that partly or entirely conveyed over into the dammed reach of River Fehér-Körös upstream of Gyulai-dam. From the latter one the water could be conveyed into the canal Elővízcsatorna. As a result, the project would turn from a local measure into a regionally important scale.
