The horizontal configuration of Prosna river bends description with cosinegenerated curve

key words: river horizontal configuration, river vertical configuration, river bends, river bed topography

Summary:

This article presents characteristic of cosinegenerated curve, its equation, shape and curvature. It presents the methodology of curve parameters (minimum radius and curve length) setting witch describe real river bends in map’s co-ordinates. The methodology was used for describing horizontal configuration of river bends down Prosna river section form 94+330 km to 93+660 km located below designed Wielowieś-Klasztorna water reservoir. On the basis of bends parameters numerical modeling of bed topography was made. Results of modeling were compare with results of in situ surveys. The result of model calculations and in situ surveys is horizontal and vertical configuration dependence down investigate river bends. On the basis of surveys results it was set that the calculated river bed topography describes real bed topography in a good way. It was also set that calculated curves corresponds with configuration of river bends.
