The Simulations of Glacier Burst Flooding in Uttarakhand, India Using iRIC-Nays2DFlood

Abstract

In February 2021, The Nanda Devi glacier brust in Uttarakhand, Northern India. It caused flooding in the Dhauliganga River and the Rishi Ganga River that impacted damage to life, property, and infrastructure in the downstream area. This research focused on flood simulations using iRIC-Nays2DFlood. The Foundation of Hokkaido River Disaster Prevention Research Center, Japan, has developed the model to test and simulate the Dhauliganga River and the Rishi Ganga River. The results revealed that iRIC-Nays2Dflood had consistent behavior and was very similar to the behavior of flood in the Dhauliganga River and the Rishi Ganga River. However, flooding in remote areas and no geographic, hydrological, or meteorological data. Furthermore, the results of simulations using iRIC-Nays2DFlood can be used to create animations that are easy to understand and can be applied to study the effects and flood preventive planning in the future.
