What about the obstacle option. Does this approch uses just manning's "roughness", or energy equation? Another word what is the most appropriate method to model an obstacle utilizing a one-dimensional, steady flow HEC-RAS program?
Thanks again
Does anyone knows why when we model an obstacle in HEC-RAS using just the pier option(as an obstacle) from bridge modeling without letting the water to touch deck, the W.S.E. increases, while if you model the same obstacle with the same dimensions as the pier using the ground geometry, the...
Thanks for the reply. I do not have an image. Additionally the Dolphin structurs are located approx. 100' to 80' U/S of the bridge. The original or pre-existing model (without the structures) was done in HEC-RAS, therefore I want to use the same program and model these structures to determine...
Upstream of a major bridge, a fender system was constructed to prevent damage to the bridge piers by the accidental barge collision. The system consists of individual cylinder shaped structure constructed of sheet piles driven to the river bed in a circular shape (30’ diameter). They are called...
