Flood Hazard Assessment of Baitarani River Basin using One-Dimensional Hydrodynamic Model

EasyChair Preprint no. 4184

12 pagesDate: September 14, 2020


The present work focuses on the use of topography and imagery, based on remote sensing in a GIS plat form for Baitarani River's integrated flood analysis, which is one of the most flood-prone zones in India. Flood frequency analysis is carried out for the flood data from 2001 to 2018. The work has been carried out using the maximum flood for the year 2015 with value of 7688 m3/s discharge.

The current work uses a methodology that combines the HEC-RAS and Arc-GIS application tools for better vision of flood monitoring analysis, which is a non-structural measure of flood management system. The work is sorted in three phases; in the first preparation phase TIN generation has been done from the DEM with other initial modifications, while in the second execution phase pre-processing on HEC-GeoRAS Tool is carried out and data is exported to the HEC-RAS for computing the water surface profiles for the unsteady flow. In the third phase, flood depth and its extent for the flood hazard analysis is done. The recommendations from this study are; either to increase height of banks or construct a retaining wall at certain sections in the downstream part of Jajpur town in Odisha state.

Keyphrases: Arc GIS, FLOOD HAZARD ANALYSIS, Flood modelling, HEC-GEORAS, HEC-RAS
