For steady flow hydraulics in HEC-RAS, a junction can be modeled by either the energy equation or the momentum equation. The energy equation does not take into account the angle of a...

In the current version of HEC-RAS (v 4.1.0) there are two methods of modeling the hydraulics at a junction for unsteady flow. By default RAS selects the Force Equal WS Elevations (Forced) method, …

There are two ways to form a junction: (1) a tributary reach will split an existing river reach and (2) the end points of three reaches will be moved and snap together. Either case, RAS Mapper...

We're now going to link the HEC-RAS cross-sections with their calculated DSS flows from HEC-HMS. The following table shows the relationship between the junctions in the HEC-HMS basin model and …
