Abstract: Basin / regional water quantity and quality joint configuration has been studied, because the current water allocation is lack of water quality considerations. In this paper, the authors expound the theoretical basis of water quality and quantity allocation, construct the equation of supply-demand balance and water consumption balance, establish simulation system of water quality based on optimal allocation of water system, put forward the optimal allocation of total pollutants, and analyze the realizing way of dual water supply and the coupling relationship of different models. Based on the improved concept of “three-time balances”, some ideas of decision have been put forward to identify the water shortage types, set the joint allocation plan of water quality and quantity including the pollution control. The outcomes of this study can provide a theoretical basis and method guidance for water quantity and quality joint configuration.

Key words: water quality and quantity; water allocation; three-time balance; total amount distribution; identify water shortage types
