Abstract: | Changes in climatic variability and LULC change play a pivotal role in watershed hydrology. newlineTo understand the impact of LULC and climatic variations on watershed hydrology, a study newlinewas conducted in Silwani Watershed using SWAT model. The quantitative analysis of newlinemorphometric parameters was conducted to understand the important aspect of the newlinecharacterization of watersheds. The Mann-Kendall (MK) test was employed to analyse the long newlineterm meteorological variables (rainfall, maximum and minimum temperature, diurnal newlinetemperature and evapotranspiration) for the detection of spatial and temporal trends. Satellite newlinedata (CARTOSAT- DEM, - 30m resolutions) was used in this study to understand the drainage newlinecharacteristics of the watershed. About 22 important parameters (Linear, Aerial and Relief newlineaspects) have been calculated in this study to understand the characteristics of the watershed. newlineAlso, Land use and land cover statistics and maps were prepared by using the Landsat satellite newlinedata for the years 1990, 2000, 2010 and 2020. newlineThe result of MK test of annual and winter season maximum temperature revealed an newlineincreasing trend. In contrast, in the monsoon season and summer season, none of the stations newlineshowed a significant trend. Also, in the case of minimum temperature, the yearly and winter newlineseason stations showed a significant increasing trend. The trend of the diurnal temp of monsoon newlineseason of Jharkhand has exhibited a significantly declining trend in the entire district except newlinefor Giridih. The annual monsoon rainfall of most of the stations exhibited a significantly newlinedecreasing trend in the study area. At the Godda station, annual rainfall showed a maximum newlinedeclining trend (Sen s slope = -2.49). The yearly evapotranspiration does not exhibit any newlinesignificant trend during the study period. The information about the spatial and temporal newlinevariability in a rainfed agricultural dominant area is important for sustainable development. newlineResults of quantitative analysis of morphometric parameters conclude that waters |
