HEC-RAS Reviews & Product Details

I like that fact that HEC-RAS is free of cost and has all the basic functions to perform hydraulic analysis. Review collected by and hosted on G2.com.

Some functions are old in HEC-RAS and can be modernized with time but I know they are updating the software regularly. Review collected by and hosted on G2.com.

Stream and section cut. Flood inundation mapping. Review collected by and hosted on G2.com.

Stabilize a unsteady / dynamic hydraulic model. Review collected by and hosted on G2.com.

Is able to simulate flood condition (with top view) and able to know how far the impacted area Review collected by and hosted on G2.com.

Sometime the result is not logic, for example the result for the bed surface (long section of the river) Review collected by and hosted on G2.com.

From the actual survey, i get profile of stream and then determine water level in the stream. it is useful for bridge and spillway designq Review collected by and hosted on G2.com.

Manual entry of the Data. arrange data in excel and then entry in HEC RAS required quite large time Review collected by and hosted on G2.com.

Analyzing unsteady flow state which is complicated for manual analyzing Review collected by and hosted on G2.com.

The data to generate the analysis sometime too complicated Review collected by and hosted on G2.com.

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.

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.

Creating interpolated cross sections for modelling. Review collected by and hosted on G2.com.

The automatic set up of chainage when adding my cross sections. Review collected by and hosted on G2.com.

We say all models are wrong, but some are useful. To make even this true Hecras has made this posssible Review collected by and hosted on G2.com.

Nothing for now. UI could have been a bit better though. But overall i would give a 9/10 Review collected by and hosted on G2.com.

It’s easiness to model hydrological processes. Review collected by and hosted on G2.com.

Limited undo and redo potential with the current version. Review collected by and hosted on G2.com.

It's simple, free, runs smoothly, and recognized as a standard program in my country.

It’s important that HEC RAS tell you where is mistake that you made.

Also it’s public version and free available on HEC web site. Review collected by and hosted on G2.com.

Ther is no 3D modeling in hec ras, but it’s not big dislike Review collected by and hosted on G2.com.
