Application feasibility of the novel SWAM Water-Cycle and Allocation Model in the Guangdong-Hong Kong-Macao Greater Bay Area

At present, there are still problems, such as uneven regional distribution and low per capita ownership of water resources in the Pearl River Delta, so solving the problem of water resource allocation is still a hot spot that needs continuous attention in the region today. For a long time, many experts and scholars have proposed models such as WEAP (Water Resources Assessment and Planning) and SWAT (Soil and Water Assessment Tool). Based on the advantages and disadvantages of the current situation of water resource allocation in China, this paper explores and analyzes the applicability of the newly proposed SWAM (SWAM Water-Cycle and Allocation Model) configuration model, compares the previously proposed model, and finally draws conclusions. In this work, the author analyzes the adaptability of SWAM model in the Pearl River Delta region from various aspects and concludes that the SWAM model can effectively alleviate the problems of water resources in the Pearl River Delta region.
