GeoHECHMS Reviews & Product Details

GeoHECHMS speeds up watershed modeling by automating subbasin delineation, Curve Numbers, and Time of Concentration calculations. As an advanced data wrapper to industry-standard HEC-HMS, it simplifies workflows and accelerates common hydrologic preprocessing tasks needed for HEC-HMS modeling. Engineers use its AutoCAD-compatible interface to pull land use and soil data, compute TR 55/TR-20 parameters and simplify pre- and post-development scenarios for seamless detention/retention pond design. The software supports multiple rainfall distributions and routing methods, such as Muskingum, Kinematic Wave, Modified Puls, and Snyder Unit Hydrograph. Both US and metric (SI) units are supported, making GeoHECHMS a powerful solution for accurate watershed modeling and hydrologic analysis.

"Considerable time-savings"

4.5/5

What do you like best about GeoHECHMS?

Automated tools for basin delineation, determining land cover, time of concentration. Review collected by and hosted on G2.com.

What do you dislike about GeoHECHMS?

LiDAR import requires the assignment of project coordinate system one-by-one. The global assignment would be nice. Review collected by and hosted on G2.com.

"Modern, Comprehensive Solution for Hydrologic Analysis"

5/5

What do you like best about GeoHECHMS?

GeoHECHMS provides all of the external resources that could be necessary for a complete hydrologic analysis. The original Army Corps of Engineers HEC-HMS software always seemed like an "old" software regarding its interface and features. GeoHECHMS upgrades it to a modern software. Review collected by and hosted on G2.com.

What do you dislike about GeoHECHMS?

I have not used the software enough to discover its downsides. Compared to regular HEC-HMS, GeoHECHMS is an upgrade, and I haven't used any other software like it to compare it against. Review collected by and hosted on G2.com.

"Effortless Stormwater Modeling with Excellent Support"

5/5

What do you like best about GeoHECHMS?

Easy to use and works well modeling stormwater runoff from complete site grading. Much easier to use than the USCOE base program. Importing linework and grading surfaces from Civil 3D is easy to complete. CivilGeo support is very responsive and helpful. Review collected by and hosted on G2.com.

What do you dislike about GeoHECHMS?

Does not provide a benefit when analyzing small sites. Referencing support files can get tricky when sharing with collegues. Review collected by and hosted on G2.com.

"Effortless Hydrology Modeling with GeoHECHMS"

5/5

What do you like best about GeoHECHMS?

CivilGEO’s GeoHECHMS has been great to use. The layout is clear, the tools make sense, and it takes a lot of the hassle out of building and updating HEC-HMS models. It runs smoothly and genuinely saves time on projects. Overall, a solid, user-friendly bit of software that makes hydrology work easier. Excellent customer support and constant updates to improve the software. Review collected by and hosted on G2.com.

What do you dislike about GeoHECHMS?

Reaches are sometimes inaccurate on a design surface created with a very small cell size. Review collected by and hosted on G2.com.

"Fabulous"

5/5

What do you like best about GeoHECHMS?

Can model both natural and urbanized watersheds. Supports mixed development watershed conditions. Highly modular architecture allows for easy integration of hydrologic modeling needs and graphical Environment Includes a user-friendly Watershed map visualization, data entry utilities. Its advanced Hydrologic Capabilities Supports a wide range of hydrologic processes: Infiltration (e.g., SCS Curve Number, Green) Evapotranspiration, Baseflow and Channel Routing. We Can Add storage Capacity, Nodes, and In Addition to its Interoperability, it works with other HEC software i.e., HEC-RAS). and uses data storage and retrieval, enabling integration with other hydrologic and hydraulic H&H models. Review collected by and hosted on G2.com.

What do you dislike about GeoHECHMS?

All models in HEC-HMS are deterministic, they assume exact knowledge of initial and boundary conditions. This can limit realism in scenarios where uncertainty or probabilistic behavior is important. Parameters are assumed to be time-stationary, they don’t change over time. Simplified Flow Representation and it does not support complex networks in urban engineering systems. Lack of advanced urban pipe network features creates redundancies and uncertainties. For long simulations, parameters must be manually adjusted between segments. This creates time-consuming issues.

"Very supportive staffing and accessible resources."

5/5

What do you like best about GeoHECHMS?

The most helpful is the staffing as well as the detailed error codes when running the software allows for efficient tried and error/ solving issues when they arise. I also appreciate that there are multiple ways to get the same function whether its the ribbon or right clicks. Review collected by and hosted on G2.com.

What do you dislike about GeoHECHMS?

Some of the work flow is less straight forward and it is very sensitive to missing information/parameters. I would like it if the inputs where more guided instead of an iterative process. Review collected by and hosted on G2.com.
