I have setup my model carefully. When I am simulating it then it is giving error "as the h-point :River Name:82404.00 meter the water depth greater than 4 times max depth"
I checked my cross sections but not getting the proper solution of it. When I am trying to see my results in Mike View then it is not displaying anything.
I would say it´s probably a problem with your boundary conditions. Your model is storing water in the domain and the water depths increase up to a point which Mike 11 finds unreasonable. You might want to verify that the downstream boundary condition is taking water out of your model (maybe just a problem with the sign of the values in your rating curve)
If change BCs not work. You might check your mesh angle or/and bathymetric data interpolated from the real measurement. The point is to make sure you have a relative smooth geometry.
There is an explanation on this error in the MIKE 11 HD FAQ:http://faq.dhigroup.com/default.asp?module=MIKE+11+HD&ID=209. I would suggest you look at your bathymetric data first. If there are certain cross-sections which are close to each other, remove some and try running it over again. All the best!
Shang-Shu Shih and Rodolfo Alvarado Montero thanks for your answers. i solved the problem. now my model is stable. thank you guys
I am getting higher flow velocity at several cross sections mainly in the downstream portion. How can I overcome this problem. What parameters could be sensitive for it. I think it is occurring due to instabilities, if I am right??
I checked my all the cross sections. In my catchment, the main river length is around 150km and the slope vary from 1400 meter to 6000 meter.
Anybody would please solve this issue.
Thanks in advance
The problem is most likely your boundary conditions. You must follow the cross-sections, especially when work interpolation for the cross-section
This is a very common problem with Mike11 HD model and is hard to fix. Perhaps DHI should look at this and try to fix it.
This could be due to insufficient number of cross section or computation time steps.
my recommendation would be provide additional cross section where there are these error occuring and reduce computation time steps.
