Case Study: Forecasting the Lower Vistula Bed Deformation without and with Development of Dam Cascade

The case study presents the results of numeric simulations of deformations of Vistula River bed downstream the Wloclawek Dam, with and without development of the downstream dam cascade. Calculations were performed using a one-dimensional flow model MIKE11 with a river transport module. Using synthetic inflow hydrographs, predictions were performed for 39 year period (2016-2055). Results indicate that the construction of the dam cascade will reduce the erosion of the river bed downstream the Wloclawek dam.
