Study also shows that element geochemical method is useful in provenance discrimination, because it can effectively avoid the influence of hydraulic sorting. 分析表明元素地球化学方法在沈积物物源判别时，可有效的避免水动力因素影响，取得较好的效果。
On the base of its past process, present situation and new development, this Paper predicted the amin direction of the research upon the hydraulic numerical simulation. 本文在分析了环境水动力数值模拟的发展过程与研究现状的基础上，结合当前学科发展动态，预测了其未来研究的主要方向。
