HEC-RAS Overview

What is HEC-RAS?

HEC-RAS is a computer program that models the hydraulics of water flow through natural rivers and other channels. The program is one-dimensional, meaning that there is no direct modeling of the hydraulic effect of cross section shape changes, bends, and other two- and three-dimensional aspects of flow.

I have a normalization river project, which is we have to check the capacity of the existing river (check to flow Q50) and we have to check the sloping stability of the river against the shear strength from the water flow. And i did it with hecras. Review collected by and hosted on G2.com.

What do you like best about HEC-RAS?

Hec-Ras is a User-friendly hydraulic analysis and modelling software. I have been using this for more than three years for my infrastructure projects. These hydraulics tools are great to model the 2d induction boundaries to determine the Peak flow, velocity and flood depth. The main highlights of the simulation of the final result are really cool. The simulation for any storm duration is possible. Most reliable software to analysis the peak flows and flood path. So it can determine the floodplain map, sediment transport analysis, flood control and storm drain system design and analysis. Review collected by and hosted on G2.com.

What do you dislike about HEC-RAS?

I don't find any issues until now with the software. Unless. I heard the problems with the unsteady flow with numerical analytical results. Also, River Profile create and import from Hec-Georas is like to stair and seem to be not correct but Civil 3d show better and smooth Profile for River. Moreover, Importing data and validating is a tedious task. When I Import Geometry Data From ArcGis into Hec-Ras, in Some Cross-Sections, LOB DownStream Reach Length is Negative.

In addition to that HEC RAS is not able to recover geometry data from the HDF file. In RAS Mapper, I import the MDT and it goes smoothly in the Geometry window of HEC RAS. Then, I edit the different layers (rivers, banks, etc.) in RAS Mapper. Apparently everything is going well, but when I'm going to save the geometries, I always get the error that can be seen below. Of course, the layers are not seen in the Geometry window of HEC RAS, it is as if they were empty. The error says: "Error reading geometry data from file: path/*.HDF"So the major issue with the HEC-RAS is depended on computer configuration if the input data is big and the simulation time and analysis period is more.

Recommendations to others considering HEC-RAS:

HEC-RAS utilizes a graphical user interface to make software using both easy and efficient. It also contains several different analysis tools for rivers. Included is a modelling system for water surface profiling and flow calculation, as well as a model for flow simulation. The system is capable of simulating sediment transport and calculating the movable boundaries of a river. There are also included analytics to determine water quality and to model general water temperature. Flat files are used for data management, organization, and storage. Also included is a comprehensive set of mapping and graphing tools. Review collected by and hosted on G2.com.

What problems is HEC-RAS solving and how is that benefiting you?

2d Modelling

I have been using this software for multiple infrastructure projects. The major task to study the flood modelling for the entire site during pre-development and post-development of stormwater runoff. The simulation for any storm duration is possible. Most reliable software to analysis the peak flows and flood path. So it can determine the floodplain map, sediment transport analysis, flood control and storm drain system design and analysis. It helped on modelling/forecasting river floods (influence of environmental factors and climate change; the impact of flood lands on ecosystem services). Review collected by and hosted on G2.com.
