Comprehensive water resources and environment planning based on generalized evaporation-transpiration water consumption control III: Application

The study focused on the application of the theory and methods of integrated water resources and environment planning based on ET control to the Tianjin city. Seven water amount control schemes with the Middle Route of South-to-North Water Transfer Project taken into account were recommended as follows: 7.47 billon m3 of total ET control, 3.23 billon m3 of surface water consumption control, 0.12 billon m3 of groundwater consumption control, 0.32 billon m3 of ecology consumption control, 2.88 billon m3 of living_industry-agriculture consumptive control, 0.102 billon t of ammonia N discharge, 0.75 billon t of COD discharge and 1.64 billon m3 of outflow to sea. The results revealed that the theory and methods of integrated water resources and environment planning will play a important role in solving water resources scarcity, ground exploration, water environment pollution, and greatly promote the sustainable development in society, economy, ecology and environment.
