Reminder for engineers working with HEC-RAS flood models. One of the most common issues I see in river studies is this: A model runs smoothly, produces stable water surface profiles, and looks ...

The existing irrigation canals in the Nile Delta were constructed nearly 100 years ago prior to the construction of Aswan High Dam 1. As the Egyptian population increased and so the extension of ...

A pet peeve doing alternative analyses using HEC-RAS in 1-D. In general, you should have about the same number of cross sections in an existing conditions model and proposed conditions model.

HEC-RAS is designed to perform one and two-dimensional hydraulic calculations for a full network of natural and constructed channels … steady/unsteady flow, sediment transport, water quality modelling ...
