1) The inflow hydrograph generated by a 100 year storm is given in the Table 1. A flood control reservoir has spillway crest with elevation of 105 meters. The reservoir has the elevation-storage-discharge relationship shown on Table 2. Assuming the reservoir is initially at the elevation of 103 meters, determine the outflow hydrograph and compute the reduction of peak flow in percentage (%). Plot the inflow and outflow hydrographs.
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.
This is for water resources Engineering. Please show steps and formulas so I can understand.
