- With the use of two-dimensional hydrodynamic model CCHE2D it has been calculated a flood passage through the contemporary Vistula River channel in Warsaw. The channel reach is between km 501-521 and limited by flood protective dikes. For the model calibration it has been used a measurement of water surface of the 1997 year flood. To study the floodplain high vegetation influence on the river flow resistance it has been calculated two scenarios of flood passage. Scenario zero of recently existing vegetation and scenario one of tall trees clearance at the right bank between km 509-519. Simulations have been run for the discharges Qp1% = 6430 m³/s i Qp0,1 % = 8250 m³/s. Obtained results shows that the highest lowering of the water surface by 0,56 m due to trees cutting occurs at discharge Q0,1% on km 510. In the river reach km 511-516 river flow has a very high average velocities in vertical, exceeding in some places 3,7 m/s. Verification of these results has been done by comparison with hydrometrie measurements.
