Stability Problem

[Robert]

Hi

I would like to ask you for advices.
My model is partially stable:
– location vs. time (max flow) (see appendix 1) https://drive.google.com/file/d/0B6wWUzbPUM0dR3FhQU15WkR1WG8/view?usp=sharing
– Volume of hydrograph
– Translation an Attenuation of wave

but
he has a error in the WSE above bridge (see appendix 2, 3).

I was trying to use all stability possibilities (CS spacing, Time computation, HTab CS and Bridge), but my problem is persisted!

thank you for your advices
regards
Robert

Hi

My errors (abrupt increase of WSE) are results of abrupt decrease velocity before the bridge.
What method can I solve this problem?
My bridge are small obstructions without pillar!
