Abstract | Proper planning, rational development and optimum management of water supply have become essential in Greater Kathmandu which is being confronted with the rapid population growth and increasing water demand. This study addresses these issues based on multiple objectives governing the integrated use of surface and ground water resources. Appropriate linear programming based optimization models have been developed and applied for identifying alternative planning and development plans. The alternatives have been evaluated by a muti-criteria decision-making method. Both the surface and ground water resources available within the study area are assessed and analyzed for the optimum allocation of water resources to accomplish water demand in 2001 A. D. Some alternative schemes incorporating artificial groundwater recharge and inter-basin transfer are identified and evaluated for 2020 A. D. The results of the analysis indicate that trade-offs exist among different economic, supply reliability and environment related performance criteria (i.e. cost, supply shortage with respect to demand and downstream flow) of the alternative designs and operation policies. The solutions from the planning model show that the surf ace water sources within the valley jointly with ground water potential of Greater Kathmandu can fulfill water demand of 2001 A. D.. For long-term water supply system, run-off-river type imported surface water with flexible groundwater development is found to be more promising for future water demand in 2020 A.D., but it depends on the feasibility and reliability of supply from ground water system. Otherwise storage type surface water incorporating inter-basin transfer with existing ground water facilities is found to be promising for future water supply development. |
