What it did was controlled the flow of the water in the colorado river so that anything downstream there would be no crazy flooding which was exactly what the Yuma valley

when establishing the chlorophyll a criteria. For example‚ reservoirs associated with “run-of-the-river” dams typically have small hydraulic head‚ limited storage area and short retention times and are less likely to be susceptible to conditions that can lead to eutrophication or promote excessive algal growth. In contrast‚ reservoirs associated with larger dams‚ such as storage or hydroelectric dams‚ are more likely to have longer retention times‚ providing a greater potential for incoming nutrients

flooding‚ and our farms are influencing droughts and floods. 4. How do levees‚ dikes‚ dams‚ and aqueducts differ from one another? What is the primary purpose of each? Levees‚ dikes‚ dams and aqueducts differ from one another because a levee is an enlarged bank built up on each side of river to prevent flooding.

As soon as the water level reached the mouths of the canal‚ the dams that blocked the canals from the Nile River were opened. After these dams were opened the basins and canals were flooded. When the highest water level was attained‚ the canals were once again blocked‚ leaving the remaining water to dissipate from either evaporation or slowly be drained

Section 1: Introduction and Background Introduction Green energy can be referred as energy production that is not just better than fossil fuel but this energy is friendly to the environment also. Green energy comes from natural sources as sunlight‚ wind‚ rain‚ tides‚ plants‚ algae and geothermal heat. Waste incineration also can be a source of green energy. Green energy is often outlined as power source that do not pollute and are replenish-able. Green energy is very good to replace fossil fuels
