Delineating Water Source Protection Area Based on Two dimensional Flow pollutant Model

Abstract:

This paper describes the general principles and research methods of delineating source water protection areas based on the two dimensional flow pollutant model. Taking Gong Lake as an example, the two dimensional flow pollutant model of Gong Lake was first built and run according to Delineating Source Water Protection Areas (HJ/T338—2007). The water transfer in Wangting hub was regarded as the main impact on water quality in Gong Lake, and the water quality indexes such as CODMn, TP and TN in different situations were analyzed in 2010. Then numerical simulation was used to delineate source water protection area on the basis of the two dimensional flow pollutant model and GIS method. The study results provide the technical support for delineating source water protection areas.
