An Integrated Distributed-Hydrologic and Watershed-Management Model: A Case Study in the Heshui River Watershed of Southern China
A structure-distributed hydrologic model is firstly proposed to simulate rainfall-runoff relationships. Based on URHM, a simulation-based integrated watershed management model (SIWAM) is further developed for supporting analysis of sustainable economic and watershed management policies. The SIWAM model is applied to the Heshui River watershed located in the south of China for demonstration study. Three scenarios (sustainable development, economic priority, and environmental priority) are designed in the study with different economic and eco-environmental considerations. Results from the SIWAM model show that the total system net benefit over the planning horizon from 2007 to 2022 under the three scenarios, with the values of RMB ?67. 08, 62.09 and 54. 79 billion, respectively. It is also implied that the sustainable development scenario would be preferred due to relatively high economic benefit and low environmental cost.
