It is decided to construct an artificial lake in the Bahr Al Najaf, for touristic and storage purposes of 5000 m³. The soil is generally sand with a specific gravity of 2.65, water table at about 2 meters below N.G.L and the soil is saturated up to surface level, with medium density with the degree of compaction of 60%. The maximum laboratory dry density is 19 kN/m3. Answer the following questions: 2. We can increase the field density by: а. increasing the water content O b. decreasing the layer thickness and No. of roller passes O c. increasing the weight of soil mould d. increasing the gradation of the soil O e. none of these
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.
