随着经济和社会的发展,南通市远期需水量将进一步增加。本文通过对农业、工业、生活以及生态用水量相关指标的分析和计算,预测了2030年南通市总需水量和高峰期需水量。在此基础上,通过MIKE11水动力模型,模拟了不同方案下主要控制点的水位变化和最低水位。结果表明:50%和75%用水保证率下引水基本满足要求,95%用水保证率下需增建60~100m~3/s的通吕运河泵站以解决用水矛盾。
With the economic and social development, Nantong future water demand will further increase. This paper predicts the total water demand and peak water demand of Nantong City in 2030 through the analysis and calculation of relevant indicators of agriculture, industry, life and ecological water consumption. On this basis, MIKE11 hydrodynamic model was used to simulate the water level changes and the minimum water level of the main control points under different scenarios. The results showed that water diversion basically met the requirements of 50% and 75% water guarantee rate, and 95% water guarantee rate needed to build 60 ~ 100m ~ 3 / s Tongyue Canal pumping station to solve water contradiction.
