QUALITATIVE ANALYSIS OF EROSION AND SEDIMENTATION PROCESSES ON THE VISTULA RIVER REACH DUE TO FLOOD WAVE PASSAGE

Keywords: flood water, erosion, sedymentation, numerical model, low boulevard
Abstract:

In the paper the results of numerical simulations of the two-dimensional flow field and potential morphological changes due to flood wave passage in the channel of Vistula River in surroundings of the Wawel castle in Cracow city were presented. For these calculations CCHE2D model was used. The special attention was paid to local variation of water surface level and shear stress distribution due to complex geometry of the low boulevard and the river channel bent. In the effect of proceeded analysis, regions of strong erosion impact were identified. Its localization was confronted with partly documented knowledge of the low boulevard damages documented after flood from the may 2010 year. Additionally, results of qualitative analysis of channel morphology changes were presented. In this way preliminary stability of the river channel reach was evaluated. Basing on the results of numerical computations and available theoretical knowledge concerning secondary flows occurring in meandering river’s channels, the origin of local bumps in the channel bottom along the bent of the Vistula River were interpreted of going to be interpreted.
