Abstract
Based on the theory of decompose-coordination for large-scale systems, a systematic optimal operation model with multi-objective programming is developed for optimal allocation of water resources in Guangzhou City, South China. The methods of hierarchical analysis and step by step toleration obligation are used in the process of coordination through the sub-systems. Through the integrated regulation of 13 reservoirs and 6 main rivers and the regional watersheds, estimated water amount for dry year (P = 97%) is distributed optimally to 14 water resource units to meet water demand in the year 2020. Water shortage due to lack of runoff and insufficient water supply projects is analyzed. The scheme of water allocation within seven water resource districts is put forward to match the sustainable balance of water supply to water demand in Guangzhou City.
