Modeling vault
Such estimated group members, with a query’m practicing hydraulic modeling of a river, but want to work a concrete vault with either elliptical or channel cover (As shown in the picture), but do not know how I can HEC-RAS enter this type of modeling sections to be as real as possible. In the entry and exit has aletones input and output (I do not know if these can be modeled as walls) and how they have to enter the program.
The total length of the dome is 300 meters in a straight line, you want to work as well as you want to fill all this area to work on a platform that can be used as a warehouse, for this is to be channeling the river through dome for this pass under the platform closed form.
Attached is a picture taken from google where a vault in Hec-RAS, which is what I want to do but do not know how, thanks shown.
For your help in advance I am very grateful for your answers.
