Water pollution is a health hazard to people, and can be damaging to the environment. Water quality modelling can be used to better understand sources of pollution and how the quality of the receiving waters can be improved.
This guideline document describes water quality modelling approaches and discusses options for use at provincial level in China. The aim is to provide an overview for leaders in an Environmental Protection Bureau or Water Affairs Bureau who are contemplating water quality modelling. It should be read in conjunction with Advisory Note 1.5 - Use of Qual2K in Water Quality Modelling and Example 1.5 - Water Quality Modelling in Chaoyang Municipality area Liaoning Province.
This document covers the following topics:
existing water quality modelling in China: provincial level modelling; Chinese universities’ and institutes’ models; donor funded projects.
available modelling tools: types of surface water models; widely used modelling software; limitations of water quality modelling.
implementing a water quality model: choosing modelling software; constructing a model; data requirements; running the model; Interpreting the results; water quality responsibilities; training and staff requirements
