Název v původním jazyce

Numerical Solution of Re-suspension of Cohesive Sediments in the Reservoir of Střekov on the Lower Reach of Czech Elbe

Popis výsledku v původním jazyce

Paper presents the results of numerical modelling of re-suspension of cohesive sediments settled behind spurs and dikes at the end of backwater of Střekov river reservoir. The monitoring of water, sediment and suspended load quality of Czech Elbe between1991 and 2001 showed a considerable improvement of environment quality in the main channel of Elbe and even in small weir reservoirs along the waterway, but, in the bights of reservoirs of higher weirs, there are layers of sediments containing old pollutants. These are resuspended during catastrophic floods and then transported downstream like suspended load making the water quality worse. Its re-suspension may be predicted using at least two-dimensional mathematical model of the water flow. Using themodel FAST 2D together with the data processing program, the authors obtained a tool for modelling of behaviour of cohesive sediments during a definite flood.
