Compute the runoff volume due to a rainfall of 15 cm in a day on a 550 ha watershed. The hydrological soil groups are 50% of group C and 50% of group D, randomly distributed in the watershed. The land use is 55% cultivated with good quality bunding and 45% waste land. Assume antecedent moisture condition of Type-III and use standard SCS-CN equations.
Reservoir and Streamflow Routing
In hydrology, a reservoir is usually a natural pond that is enlarged or made using a dam to keep the water clean. Reservoirs or dams can be constructed in several ways, including controlling the existing watercourse, disrupting the watercourse to form embayment within it, by digging or building any number of retaining walls.
Water Resource Systems Analysis
Water resources are natural water sources that may be as useful as water sources. 97% of the world's water is saltwater and only 3% is pure water; just over two-thirds of this ice sheet is located in glaciers. The remaining pure frozen water is found primarily as groundwater, with only a small fraction present above the ground or in the air. Natural sources of freshwater include surface water, under river flow, groundwater, and ice water. Artificial water sources can include treated wastewater (recycled water) and saline seawater.
