Changing Hydro-climatological Response of Bhadar Basin in Western India
Climate change is a global issue of today’s modern world. The global temperature is increasing and attaining new records with each passing year [Intergovernmental Panel on Climate Change (2018) Global warming of 1.5 °C: an IPCC special report on the impacts of global warming of 1.5 °C above pre-industrial levels and related global greenhouse gas emission pathways, in the context of strengthening the global response to the threat of climate change, sustainable development, and efforts to eradicate poverty. Intergovernmental Panel on Climate Change]. The changes in temperature affect the hydrological cycle and through changing rainfall patterns. As a result, some areas receiving more and more rainfall and experiencing flood while others have less rainfall and have to deal with drought. The increased frequency of extreme rainfall events is another noted feature of climate change. Rainfall is the key element for well-being of the people in the country like India for larger dependency on the agricultural activities. Different studies highlight significant changes in rainfall pattern over western part of India, Gujarat. The peninsular region of Gujarat, known as Saurashtra is recognized for its flashy rivers and dry hydro-geo-morphology. Bhadar is one of the major rivers of Gujarat and largest river in the Saurashtra region. The Bhadar River basin is observed to experience frequent flooding in the recent years with 2021 flood causing heavy loss in the region. This study is taken up to access system behavior and understand different hydrological processes for Bhadar River basin. Hydrological model is useful to present the real-world system in the simplified form. Here, in this study, a physically based, semi-distributed model, namely, Soil and Water Assessment Tool (SWAT) was used. The study reveals changing hydro-climatological response of Bhadar basin. Findings of this study provide useful inputs to policymakers, farmers, disaster management authorities for management and planning of water resources in the region.
