The Total Control of Water Supply and Water Consumption in Tianjin City Based on WAS Model

Abstract

Water resources planning and management should constitute an integral part of the socio-economic development planning process. Models have become the core part of water resources management. In this paper, the Water Simulation and Allocation Model (WAS) was developed and applied in Tianjin City, China. The aim of the research is to provide the water control value based on pragmatic modeling approach to water planning and management in order to promote water allocation, recover ecosystem recovery. In 2030, in accordance with WAS model calculated, the ET goal control is the 643mm; the volume of sea water into the goal for 1.649 billion m3. Exploitation of deep underground water is about 3.06 billion m3. Domestic economy in rural areas are being met and the water control of domestic economy is about 37.87 billion m3; water for the Ecology is 9.51 billion m3.
