The non-tropical climate countries such as Turkey are also affected by the floods. The geographical structure of Turkey is extremely complex and varies even at short distance. Therefore, the shape and effects of the floods vary from region to region. …
WebThe question of 1D versus 2D hydraulic modeling is a much tougher question than steady versus unsteady flow. There are definitely some areas where 2D modeling can produce better results than 1D modeling, and there are also situations in which 1D modeling can produce just as good of results or better than 2D models… with less effort and … WebSpatial Modelling of Flood Inundation - Read online for free.

WebApr 22, 2024 · The HEC-RAS hydraulic model has been used for flood inundation modeling in the present study. This model can perform 1D steady, 1D and 2D unsteady flow simulation, water quality and temperature modeling, and sediment transport modeling [12, 13]. The model is programmed to perform 1D, 2D, or coupled 1D–2D hydraulic … Webhydrodynamic modelling using HEC-RAS 5.0.6 2D (two dimention) with unsteady flow.

WebThe findings of this study demonstrated that the flood model output was strongly dependent on the DEM quality with LiDAR data, indicating a high potential source for channel and floodplain topography parameterization. Schumann, et al. compared the effect of DEMs generated from airborne LiDAR, contours, and SRTM on a flood inundation model.
