ABSTRACT
Competitions for water will increase in Langat basin, with increases in population and with new and continuing
efforts to stimulate economic development, improve income levels and achieve food security. Water scarcity and the inefficient allocation of water can limit the pace of economic development in any regions, particularly when nations are unable to implement agreements that enhance the sum of net benefits generated with water
resources.
The purpose of this research project was to gain an overall understanding of the integrated water resources management, through researching the four main topics:
Water resources management.
Runoff storage.
Wetlands.
Aquifer storage and
recovery.
Competitions for water will increase in Langat Basin (Malaysia). With increases in population and with new and continuing efforts to stimulate economic development, Meeting the public’s every increasing demand for potable water is becoming a major problem for every country. The water sources available are already under stress; however, uses of Aquifer Storage Recovery (ASR) wells obviously resolve the problem as they can be used for the cyclic storage and recovery of water. The function of these wells is to store the water in the subsurface when it is readily available from the rainy season in order to have a sufficient supply of water when there is a shortage during the dry season. This technology is used for the storage of treated drinking water. Also it could be expanded to store water that is not potable but suitable for other purposes such as irrigation. This water could be stored in brackish aquifers.
IWRM should be applied at catchment’s level. The catchment’s is the smallest complete hydrological unit of analysis and management. This project focuses on determining the relationship between the volume of water that can storage in the Langat basin by using the Visual MODFLOW 4.2 Program for modeling By estimated the volume of the Langat basin Aquifer thickness map for the tow layers 3c, 3d.This study found that the total maximum storage volume in the tow layers in the Langat basin Aquifer is approximately 9724.342 million cubic meter this quantity can recharge artificially by ASR wells to the Langat basin and as a case study for the UKM campus this study found that the total maximum storage volume in the tow layers in the Langat basin Aquifer is approximately 54.26685 Million cubic Meter Can storage under UKM Camps Aquifer 3c,3d (5,6 )As sub- Langat aquifer Basin so we see by the natural recharging that we can store around 1.4 million cubic meter in the UKM campus aquifers by infiltration ,and now we can see clearly that this amount is equal 0.0258 from the amount that we can store it by artificial recharging through suitable ASR wells ,also by using the ASR advisory system we can do many scenarios of recharging and recovery in any place .
