回答：您好,我做的是河道,其实我是和hec-ras一维,MIKE11(一维的这两个模型算出来非常接近)算出来的做对比后,MIKE21的水位高很多。开边界的数据,一维和二维用的是一样的,那就是地形问题了?

分类:水动力学/知识集锦在一些水动力学模型(如MIKE21)中,会有水位(surface elevation),总水深(total water depth)和静水深(still water depth)的概念。平时实际应用中,特别是河道水流计算时,更关心的其实是水位流速,但经常会有人问到另外两个水深到底是什么,这里稍微介绍[...] 继续阅读MIKE21...

But it still needs some depth, so if you look into it, there are things to discover. What this way of working creates is sharp drawing that's never overworked. And a good sense of realism, because you're drawing what you'd expect to see. So, I'm not going to just fill it full...
