What is Hydrological modeling of catchment specific runoff-response to variable land-use/climatic conditions and trend-based hypothetical scenario generation: a study on a large river basin in Eastern India about?
The present study is an attempt toward the quantification of the impact of climate and land-use change on the hydrological prospect of the Kangshabati river basin of West Bengal. The study also simulates runoff characteristics as a response to hypothetical climatic scenarios. The scope of the study involves, first, to quantify the relative contribution of climate change and land-use change to runoff response and second, to simulate runoff characteristics as a response to hypothetical climatic scenarios. Using a combination of the SWAT model, SWAT Cup, Sequential Mann Kendall Trend Tests, surface and total runoff were generated for 1982-2017, and the mutation point was identified. The results indicate that post-2010, climate change has an overwhelming impact on runoff with its contribution being as high as 99% in the case of total runoff and 89% for surface runoff. And this finding is cemented by dynamic contribution analysis which indicates over-arching climatic impact for every decade, with a sudden increase post-2010. Change in temperature and rainfall has an expected impact on runoff, with a rise in rainfall and decrease in temperature resulting in the higher runoff than the nor
