Folks: I am using a high-resolution 2D HECRAS model to model storm flows through a proposed bridge opening with piers. I am using the SWM-EM solver to improve the model solution near the bridge piers. Is it also necessary to include turbulence modeling in the solution? Logically, it appears that ...

Folks: We are constructing a HECRAS model of a canal that includes a railway bridge supported by several rows of pile bents containing piles installed at a vertical angle that is perpendicular to the direction of flow. While bridge abutments can be sloped, it appears that HECRAS can only accommodate ...

Folks: We are attempting to model two-dimensional flow in two channel transition areas connected by a culvert. The two areas are separated by an embankment. I noticed that if we add a 2D area connector to the model and specify the embankment properties in the same window used to enter the culvert ...

​Folks: Are there any standards or guidelines in the water works or other industries for computing the head losses associated with annular axial flow between a rotating shaft and a stationary outer wall? Thanks ------------------------------ Mark Wilsnack P.E. PRINCIPAL ENGINEER South Florida ...
