花道泡水质模拟预测研究

Research on the Numerical Simulation of Water Quality in Huadao Reservoir

Delft-3D是由荷兰水力研究院(DelftHydraulics)开发设计的三维或二维可视水动力-水质联合模拟软件系统,可全面仿真水域的三维或二维循环水流水质情况。该模型不仅考虑了复杂的流体力学问题和输送过程,还考虑到众多与有关水体相关的物理、化学和生物的相互作用,使仿真结果较先前使用的水质及水力模型仿真套件所作的预测更为可靠和准确。该研究以Delft-3D软件为技术平台,对饮用水水源地花道泡引水初期的水质进行了模拟预测,初步确定了水体适合农业灌溉和生活饮用的时间,并且给当地的决策部门提出了一些建议。

Delft-3D software system was designed by the water power academe of Netherlands （Delft Hydraulics）. And it could be used to simulate the changes of hydraulics and water quality in two directions or three directions. The models not only think of complicated hydrodynamics questions and transportation process, but also think of many physical chemical and biological reciprocity, which makes the results more credibility and reliable. By using Delft-3D, the water quality of the first three years in Huadao Reservoir was simulated the time to irrigate and drink was defined. And some suggestions were given for local decision-making departments.
