Impact Assessment of Climate Change on Hydrological Parameters: Evaluation of Water Balance Components of a River Basin
In recent years, climate change has become a big concern over the world. Global warming and climate change have made the problem terrible. It has attracted the attention of researchers all over the world. Due to climate change, unusual changes are happening in the atmosphere, so accurate modeling will help us address the issue by modeling in terms of parameter finding, assessment, and estimation. Hydrological models are extensively used for different water projects to understand catchment water balance, prediction of streamline flow, rainfall, runoff, flood forecasting, and other water resource management projects. Two watersheds of the Manjra River basin, the tributary of the Godavari River basin, namely MNJR012 and MNJR013, were selected. The Soil and Water Assessment Tool (SWAT) hydrological model is used for impact assessment on those watersheds. Remote sensing data like digital elevation model (DEM), soil map, land use/land cover (LULC), and weather data are used. The simulated and observed data were then compared, and regression analysis was performed which gave values of R2 0.933 and 0.971 for Watersheds MNJR012 and MNJR013, respectively, which is closer to 1; hence, the simulated values obtained are validated. It has been observed that simulated data and observed data were in very close agreement with each other, which validated the results.
