The Effects of Climatic Alteration on the Glacial Lake Flash Flood in the Himadri Range of Nepal and Adjacent Indian Region

Abstract

The purpose of this study is to evaluate the impact that climatic alteration has on glacial lake flash floods in the Himadri range of Nepal and adjacent Indian region, which are places that are becoming increasingly susceptible to phenomenon of this kind. There has been an acceleration in the frequency and severity of glacial lake flash floods (GLFFs) as a result of rising global temperatures. These temperatures have accelerated the melting of glaciers and the development of glacial lakes that are unstable. This study makes use of historical flood data, climate models, and field observations in order to evaluate the changes that have occurred in glacial lake dynamics and the implications that these changes have for the threat of flooding they pose. The findings indicate that there is a correlation between rising temperatures and faster glacier retreat some time ago, which has led to a large rise in the constancy and intensity of (GLFFs). According to the findings of the study, there is an immediate requirement for improved monitoring, risk assessment, and adaptive measures in order to reduce the negative effects on the infrastructure and residents in the surrounding area. As a means of addressing the mounting issues that are being brought about by climate-induced glacial lake flash floods in the area, the recommendations include the implementation of integrated water management methods and the enhancement of pre-emptive alert systems.
