GeoHECHMS Reviews & Product Details

I really appreciate the program allowing the user to import shapes from dgn and allowing you to use those shapes to define your drainage area. It does not take much time to create the areas and junctions so that flows are created. Also, the reports are well written out. Review collected by and hosted on G2.com.

Automate is good for an idea of what is out there but not for review. Other than that, I like the program. Review collected by and hosted on G2.com.

The most important thing I’ve found while using GeoHECHMS is that it’s a complete package for a watershed modeler/analyzer, and it provides everything you need to carry out a hydrological analysis. To perform this kind of analysis, you typically need many types of data and information, such as land use, land cover, existing terrain data, and so on. GeoHECHMS brings these necessary inputs and data/information together in one place, which makes it much easier to work with. Review collected by and hosted on G2.com.

You need a reliable internet connection, because sometimes online DEM or other data aren’t available right when you need them to run a model. Review collected by and hosted on G2.com.

I like how easily I can pull the data and how it is integrated with the arcgis type of interface. The automation really helps speed the process up and eliminate errors. For the cost of the software, it can usually be justified within 1 hydrology model. The support and onboarding was very responsive too as they are more than willing to walk you through an entire model using your data. Review collected by and hosted on G2.com.

Due to the amount of data, the system takes a long time to run larger models and tends to run into errors more often. At least there is the option to save the data if you encounter an error. Review collected by and hosted on G2.com.

What I like best about GeoHECHMS is how seamlessly it integrates GIS data with hydrologic modeling. It takes what used to be a fragmented, manual process and turns it into a streamlined, intuitive workflow. Delineating watersheds, defining subbasins, and building models all feel connected and efficient instead of tedious.

I also really appreciate how much time it saves without sacrificing accuracy. The automation and built-in tools handle a lot of the heavy lifting, which allows me to focus more on engineering judgment and less on repetitive setup tasks.

Overall, it’s the combination of efficiency, clarity, and real-world practicality that stands out most—it genuinely makes complex hydrologic modeling easier and more reliable. Review collected by and hosted on G2.com.

One minor downside to GeoHECHMS is that, like most powerful modeling tools, there can be a bit of a learning curve when you’re first getting started—especially if you’re new to GIS-integrated workflows. Some of the more advanced features and settings take a little time to fully understand.

That said, once you get familiar with the interface and workflow, it becomes very efficient and intuitive, so the upfront effort pays off quickly. Review collected by and hosted on G2.com.

I like the new interface with GeoHECHMS Version 3. The integration of AutoCAD and being able to pull DEMs directly from the internet is my favorite feature. Review collected by and hosted on G2.com.

I would still like to be able to create quick figures with titles, scales, and north arrows instead of having to plot screen and put them on a titleblock. Review collected by and hosted on G2.com.

I have just recently started to use GeoHMS daily again since last year and havent noticed many updates or differences. Overall i love this software and we really pushed the higher ups to renew the license becasue it is so helpful. There are some smaller elements that i think could make the software even stronger and help user workflow. Review collected by and hosted on G2.com.

-A lock or read-only mode for supplied model elements would be helpful for regulatory workflows--especially when we only want to add or isolate certain features without changing the approved hydrology that is not impacted by the updates.

-Make calculation assumptions clearer and allow options. For example, when calculating TCs the hydraulic radius is assumed. However, some cities prefer velocities for channelized flow to be assumed. In the report feature include more detailed calculations so it is easier to implement in the submitted report. Or possibly allow an option to generate a well-structured TC and CN excel sheet that includes detailed calculations.

-For CN calcs include the basin name in the attribute table for the intermediate results shapefile. This way if we need to merge all of them together in GIS they still can be categorized by the basin

-Allow for several terrain layering for tcs etc. For example if we have multiple terrains and want one terrain read for part of the tc and a different one for a seperate portion.

-The report feature is very beneficial however i think AI could be implemented to help improve the context, structure, calculations, etc. This will help the user better incorporate the hydrology model and its parameters in their overall drainage report that is to be submitted.

-Allow better control of what component is being selected. Right now, if i have the HMS model on and add a cad file or other shapefiles i cannot select them while the hms model is on.

-In HEC-RAS there is a tool that allows the user to compare geometries and points out any differences. This would be beneficial in GeoHMS

-Before running the model if there are elements with no downstream connection add a pop up before running prompting the user to confirm before running. There have been times when working with large models that i have gone through several iterations and then find out that one junction is missing a connection.

I appreciate how easy it is to use, and I like that the program’s functions are straightforward and simple to manipulate. Review collected by and hosted on G2.com.

Sometimes, when we run an analysis, the integration between GeoHECHMS and HECHMS doesn’t work smoothly because we run our programs on our office servers rather than on the local network. As a result, we occasionally have to fall back on using HECHMS alone for parts of the analysis instead. Review collected by and hosted on G2.com.

Automated calculation of time of concentration and flow paths, georeferencing and real-time updates of subbasins, and an automatic routine for delineating subbasins using LiDAR data, to name a few. Review collected by and hosted on G2.com.

No comments here. I am still new to the program so not much to say. So far, it's been great. Review collected by and hosted on G2.com.

All hydrological analysis can be done within a same platform. Review collected by and hosted on G2.com.

Reprojection of the loaded terrain file (UTM, etc.) to the local state plane projection can be improved. Review collected by and hosted on G2.com.

I find the automated subbasin delineation, reaches, land use, curve number, and time of concentration very helpful. And the automatic report builder with the hydrograph plots makes it easy to see a graphical comparison of pre vs. post development. Further, CivilGeo customer support is excellent, they have an option to remote in and complete any task that you ask. I'm very impressed with their Customer support.
