There are 2 repositories under hec-ras topic.
Unmanned Surface Vehicle simulation on Gazebo with water current and winds
Python 3 interface to the HECLIB for 64 bit using SWIG. Primarily to provide access to HEC-DSS format
A three-dimensional Lagrangian model capable of evaluating the influence of flow velocity, shear dispersion and turbulent diffusion on the transport and dispersal patterns of Asian carp eggs is presented. The model’s variables include not only biological behavior (growth rate, density changes) but also the physical characteristics of the flow field, such as mean velocities and eddy diffusivities.
Scripts to control HEC-RAS V5.0 with Matlab with an application to Flood inundation forecasting
Tools for hydrological and hydraulics computational design, modeling and analysis.
Modelación hidráulica a superficie libre con HEC-RAS
Windows GUI app to generate geometric data table by tracing shapes on the screen.
An R package to produce standard graphs for HEC-RAS models.
Non github friendly repository for code presented in the article "Design of a MATLAB HEC-RAS Interface to Test Advanced Control Strategies on Water Systems"
