Abstract
Water diversion in the past often focuses on the evaluation of water quality improvement in the water diversion process,in which a fixed flow rate is used for continuous water diversion. Clear water does not fully exert the function of dilution and displacement,which causes a certain amount of waste. In this study,a MIKE 21 hydrodynamic and water quality coupling model for the Aixi Lake in Nanchang City is built by using the intermittent water diversion method. The model is used to simulate water diversion under different conditions. The results show that the time required for water diversion is affected by the amount of water diversion. With the increase in water diversion,the time difference between the two methods decreases gradually. The total amount of clean water used by the method of intermittent diversion is less than the amount of water required for continuous water diversion,when the simulated water diversion plan reaches the same goal of improving water quality. This study can provide references for water diversion of lakes in other cities.
