Rule-based water resource allocation in the Central Guizhou Province, China

Abstract

The Central Guizhou Province is the intake area for the Central Guizhou Province water diversion project (CGPWDP), a massive-scale interbasin project for transferring water from the Pingzhai Reservoir to irrigated areas and cities within the region. Severe water shortages are an ongoing feature in the region, with high demand for adequate potable water, and water for ecological sustainability and economic activities. In order to balance water allocation among sub-areas and users, a rule-based water resource allocation model was developed in this region. Based on documented annual water usage and supply, we adjusted the model parameters to reflect the actual performance of the water resource system accurately. Several water resource allocation schemes were proposed based on various contexts during planning years. The suggested water resource allocation schemes could ease water supply conflicts in suburban areas, and highlight the necessity of the CGPWDP.
