Use of ArcGIS to extract River Geometry as an input to HEC-RAS for Flood Modelling

  • Abstract:
  • An approach to generate river cross-sections from the Cartosat 1 a stereoscopic Earth observation satellite Digital Elevation model is discissed. The low resolution and the inadequate vertical accuracy of such global data present difficulties in differentiating features of hydraulic importance, which necessitate pre-processing of the DEMs before they are used. The extracted cross-sections were used in a 1D river modeling tool HEC-RAS/GeoRAS to simulate flood 2017 Banaskantha. Model results are encouraging and show good potential for using the suggested method in the areas of topographic data scarcity.
