Abstract:

This research represents the application of Arc GIS and HEC-RAS interface for 1D flood modeling of Damanganga River. Floods are among the most devastating and recurring natural hazard. It caused extensive economic losses and human lives around the word. Damanganga River in south Gujarat is prone to unexpected floods in 1994, 1997, 2001, 2003, 2004, 2006, 2013, 2016 and 2019. This paper presents a model development to determine the water level along the Damanganga River from Arabian Sea using HEC-RAS hydrodynamic model.The first phase for the modeling was done in Arc-GIS environment and function like GEO-referencing, creating Shape file, Mosaic extract by mask, etc. GIS file exported to HEC-RAS. In HEC-RAS RAS Mapper open to create terrain file and generate river center line, bank line, Flow path and cross section cut provide and save geometric data. The second phase for model execute to provide steady / unsteady flow data inserted for the result obtained to show water surface elevationfor peak discharge, need of flood gates on the storm drains are also assessed. The recommendations are done based on this study either to increase height of bank or build a retaining wall at certain section along the study reach.
