Online Class – Using HEC-RAS to Modeling Bridges, Culverts, and Floodplains

Hey RAS Users- This is a basic level steady flow HEC-RAS class.  That’s right, we start from the very beginning with HEC-RAS-steady flow theory, building 1D geometry, steady flow boundary conditions, and even introductions to RAS Mapper and 2D modeling.  I’ll be hosting weekly live sessions for this class to review the course material and […]

Negative Flows over Inline and Lateral Structures

Though it’s not very common, it is possible to get negative flows over inline structures for unsteady flow simulations.  It’s much more likely you’ll see negative flows over a lateral structure though.  Negative flows are simply discharges in your model going the opposite direction than what you have defined as the downstream direction (or primary […]
