From Floodplain Hydrology to River Analysis

Top Reasons to Use

FEMA Approved

HEC-Pack offers complimentary capabilities and includes the FEMA approved HEC-HMS technology developed by the U.S. Army Corps of Engineers.

Address Many Types of Hydraulic Studies

HEC-RAS can be used for open channel hydraulic studies, bridge and culvert hydraulic studies, and FEMA flood insurance studies. It allows engineers, reviewers, and developers to assess the impacts of bridges, culverts and other floodplain features. HEC-RAS can be used to compute a floodway and validate it prior to submittal to FEMA.

Model a Variety of Watershed Situations

Design engineers, hydrologists, and project managers are often faced with the need to simulate the effects of synthetic or historic rainfall events on watershed floodplains and/or design facilities to convey or mitigate the resulting flows. HEC-HMS can address rainfall and runoff modeling, channel and storage routing, and provides for calibration of model parameters to match recorded data and detailed reviews of model output.

Easy to Use Hydrographs

Use Graphical HEC_1 to produce hydrographs in tabular or graphic form and work with them in a variety of ways. Graphical HEC-1 makes it easy to create reports and export the output of flood hydrology calculations to spreadsheets and other document formats.
