The evidence of a flood wave passing through a catchment remains visible even for a long time after it occurs. The morphological update in the channel and floodplains, together with the processes related to the mass transport within the aquatic environment, can be regarded as flood event evidence. The advancement in hydroinformatics brought the development of numerical modeling as a tool for the solution of broad hydrological tasks. Thanks to the scenario modeling, flood events with interconnected processes can be explored in detail. This thesis is broadly focused on the mass transport initialization issue both in the polluted and clear middle-European water environments. The aim of the thesis is the evaluation of the principal issues connected with the mass transport initialization based on complex and integrated numerical modeling. The thesis brings original datasets resulting from several case studies. The aim of the thesis is also to bring a comparative study of methodological approaches evaluating the possibilities and limits regarding the accuracy of inputs vs. outputs and computational time requirements. This thesis also brings several useful comparisons and innovative solutions design. The mass transport initialization issue is solved in both balance and event-scale processed- based models... |
