RUNOFF CALCULATION OF SOLANI RIVER WATERSHED

This research uses land use and drainage maps to calculate the runoff of the Solani River. A watershed is a region where runoff collects and drains to a common location. When it rains, the amount of water that falls on the ground is often greater than what the ground can absorb. Surface runoff is the term for this extra water. The study area is around 530 square kilometres. Solani River is located between 29.84N and 30.27N latitude and 77.74E and 78.07E longitude. At a height of roughly 787 metres, the Solani River rises near Kaluwala Pass. The river stretches for 65.265 kilometres. The yearly precipitation ranges from 1200 to 1500 millimetres. Hill, piedmont, and lowlands are the three principal terrains found along the Solani River. The elevation varies between 200 and 800 meters. There are a range of land coverings and soil types in the research region. The main motivation for choosing this topic is a desire to learn more about the neighboring Solani River's hydrological system and the effects of excessive rainfall over time on the river's banks. The project's methodology is as follows: prepare both a land use map and a drainage map. After that, we'll use the rational method to determine the runoff value. Surface runoff is a crucial metric for determining a watershed's water production potential, planning soil and water conservation measures, and lowering sedimentation and flooding risks downstream
