Default Upstream water depth

Hi,

I have encountered a problem when I'm using shallow water model.
Everytime I set up my upstream boundary condition by using specify fluid elevation (fluid distribution -> elevation type), the water depth result will be much smaller than the depth expected.

For example, the fluid elevation input 81 m, the bed elevation is approximately 80m. But in the result analysis, the depth will become 0.1 m.

I have tried everything to let the depth get bigger(ie. use velocity instead of flowrate; setup the initial condition...etc), but none of them work.

I have no idea where the problem is and it's really frustrating.

Can someone help me out? Thank you!
