Are you placing your ineffective flow limits properly for modeling bridges/culverts using HEC-RAS 1-D? I am assuming that you know about the 4 cross sections that are created for modeling bridges and ...

Do you really know where to change your contraction and expansion coefficients when using a 1-D hydraulic program to model culverts and bridges? Everyone knows to change your contraction and expansion ...

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 ...

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 ...

Streamflow regimes significantly influence the geological, chemical, and biological characteristics of the stream 1,2,3,4. Humans have altered the streamflow patterns for water management through ...
