The management of a river and its basin to cater for demand in use of water.
Managing water resources requires knowledge of the relevant physical sciences and technology. Involves multiple institutional, social or political issues confronting water resources planners and managers. Two (2) Case Study: Mekong River Nile River
The Mekong river Flows approximately 4,200 km through Southeast Asia to the South China Sea through Tibet, Myanmar (Burma), Vietnam, Laos, Thailand and Cambodia.
Investment capital is becoming available to develop the Mekong’s resources for improved: fishing irrigation flood control hydroelectric power tourism recreation navigation The potential benefits are substantial, but so are the environmental and ecological risks.
Suggestions that a proposed dam in Laos could causedeforestation in a wilderness area of some 3,000 km2.Much of the wildlife, including elephants, big catsand other rare animals, would have to be protected ifthey are not to become endangered.Malaria-carrying mosquitoes, liver fluke and otherdisease bearers might find ideal breeding grounds inthe mud flats of the shallow reservoir.These are the types of issues that need to beconsidered if want to construct dam.
The impacts of a dam constructed on the Nam Pong River in northeast Thailand. The project had a number of unexpected consequences, both beneficial and adverse.Beneficial: Adverse :• Major fishery industry has • Increased erosion of the developed around the stream banks, reservoir • Silting up of the channel• Availability of irrigation • Large increase in aquatic water vegetation that clogged hydraulic machinery and reduced transport capacity
Its population of 63 million in 2000, Mostly people live along the Nile and in the Delta; where water is plenty. The population density increase of about 2% per year.
The government has ‘Horizontal expansion’,embarked on an ambitious which should increase theprogramme to increase the agricultural area from 3.4 inhabited area in Egypt million ha in 1997 to 4.1 from the present 5% to million in 2017. about 25% in the future. Cooperation with the other New industrial areas are (nine) countries in the Nileplanned in the desert, to basin is essential to enablebe supplied by Nile water. those developments.
Water resources planning and management activities are usuallymotivated, as they were in each of the previous section’s caseexamples, by the realization that there are both problems to solveand opportunities to obtain increased benefits from the use ofwater and related land resources.These benefits can be measured in many different ways. Inevitably,it is not easy to agree on the best way to do so, and whatever isproposed may provoke conflict.Hence there is the need for careful study and research, as well asfull stakeholder involvement, in the search for a shared vision ofthe best compromised plan or management policy.
