Zastosowanie modelu NCCHE2D do oceny warunków sedymentacji w Jeziorze Włocławskim

Process of sedimentation in Włocławek Reservoir has been described using echo-soundings made by Hydroprojekt on 1971 and 1992. Cross sections from echosounding have been registered to cartographic coordinates and bottom contour lines drawn. Digital model of river bottom has been calculated and raster map of bottom relief from year 1971 and 1992 have been subtracted giving the map of sedimentation balance. Hydraulic parameters such as channel width, average velocity and average depth at the cross-sections of the reservoir have been calculated using NCCHE2D model. Results are giving better understanding of the sedimentation conditions and allows to delineate three different zones of the reservoir - riverine, transitional and lacustrine.
