With reference to a located example examine how a river basin can be a multi use resource and how conflicts can arise. (25) In this essay I am to examine the ways that a river basin can be a multi use resource and the conflicts that arise from this‚ the location I am going to use will be Zimbabwe the Zimbabwe river consisting of the Vitoria falls‚ Kariba dam and shipping routes. Two uses for the river basin are hydro electric power‚ tourism; however a main conflict is flooding when the dam was built

Rivers‚ Flood and Management The draining basin hydrological cycle: The drainage basin is the area of land that is drained by a river and its tributaries. Also; the catchment area from which a river system obtains its water. Drainage basin largely ‘closed’ system- watershed – boundary of a water basin- generally follows a ridge of high land.

Hard and soft river defences on the Mississippi The dams in the Mississippi river are a hard flood defence. There are two different types of dams on the Mississippi River‚ wing dams and closing dams. Wing dams are built close together with brush and stone structures that extend from the river bank to the channel and closing dams are used to block connections between the main channel and side channels of the floodplains. The advantages of building dams on the Mississippi are that they enhance the

Hydrograph : A graph showing the discharge of a river over a given period of time. Storm hydrograph : Records the changing discharge of a river after a passing rainstorm. Lag time : This delay between peak rainfall and peak discharge. Number of factors affecting the critical time lag of storm 1

WATER CYCLE Water Cycle‚ also known as hydrologic cycle‚ is a process that is constantly recycling the Earth ’s supply of water. This is important because humans‚ animals‚ and plants all need water to survive. It is controlled by the sun‚ which produces energy in the form of heat. This heat energy causes the water in the world ’s oceans‚ lakes‚ etc. to warm and evaporate. As the water is heated‚ it changes its phase from liquid to gas. This gas is called water vapor and this process is called
