How We Use Water Group: That One Group in the Corner
How Dam’s Help Us Use Water • Dam’s provide us with power generation with the spinning of turbines. • Dam’s control our floods. • Dam’s help us with crop irrigation. • Dam’s provide us with new places for recreational activities.
DANGERS OF DAMS • The reservoir behind dams displaces wildlife and people from living areas, such as the Three Gorges Dam in Yichang, China • Dams bock rivers from salmon and steelhead, stopping them from migrating upriver to breed • Roughly 500 dams have been removed in recent years • Dams are removed because they are worth less than the cost to repair them and removal is cheaper • FERC determines the benefits of removing a dam
Water Supplies our Households, Agriculture, and Industry • Farmers and ranchers use water to irrigate crops and water livestock. • The proportions of each of these three types of use- residential/municipal, agricultural, and industrial use. • Heavily industrialized nations use a great deal for industry • Places with dry climate use more fresh water for agricultural and industrial use.
Two Uses of Water • Consumptive Use- When you take water to use as groundwater from an aquifer and don’t leave any left. • Non-Consumptive Use- When you take a partial amount of water from an aquifer to use for groundwate.
Flooding and Prevention • Flooding is a natural process • Floods can spread rich nutrients into the soil • Floods also cause damage to farms home and property of people who choose to live in flood areas • To protect from floods the government builds dams, dikes, and levees.
