1. Water Resources Management Several technique terms: Water resources development- exploitation of new water sources Water resources management-control of water utilization water demand-quantity of water to meet the requirement of use Water consumption -quantity of water used
1. Water Resources Management 1. Water Resources Management Several technique terms: Several technique terms: ¾ Water resources development Water resources development – exploitation of new water sources ¾ Water resources management Water resources management – control of water utilization ¾ Water demand Water demand – quantity of water to meet the requirement of use ¾ Water consumption Water consumption – quantity of water used
1.1 Importance of Water and Need for Control Demand Aspect: Water resources- critical to human society for their domestic, industrial as well as agricultural needs Low-cost supply of large quantities of water-one of the foundations of modern society Need for increased water supply-as the result of growing population and industrial expansion Water resources development- constructions of dams, reservoirs, river diversions, pipelines, and aqueducts to bring water from more distant, unpolluted sources

Resource aspect Water shortage- huge withdrawal of water for various water users, which creates a shortage of water for themselves and for other users Water quality problem- pollution from water disposal and surface runoff, which makes water qualitatively unsuitable for certain uses Environmental Aspect Sustainable development-long-term effects of water use and the loss of water for aesthetic and recreational purpose(quantitative) Aquatic environment-effect of pollutants on the aquatic lives and vegetations(qualitative)
