Overview

What is GeoHECRAS?

GeoHECRAS significantly speeds up HEC‐RAS model creation and review, producing better and more accurate results. Compute water surface profiles for steady and unsteady flow models, bridge and culvert roadway crossings, FEMA floodplain encroachments, stream restorations, inline reservoir structures, off-channel storage areas, and much more.

GeoHECRAS Overview (video 01:23 minutes)

Work Faster with Automated Workflows

AutoCAD, MicroStation & ESRI ArcGIS compatible graphical interface to HEC-RAS

GeoHECRAS is an AutoCAD, MicroStation and ESRI ArcGIS compatible interactive 2D/3D graphical user interface data wrapper to the US Army Corps of Engineers HEC-RAS software.

Import a variety of different data quickly and easily into HEC-RAS

Import existing Army Corps HEC-RAS models and quickly georeference them to real-world maps using included georeferencing tools.

Work simultaneously on multiple HEC-RAS models

Work with multiple HEC-RAS projects simultaneously using the Multiple Document Interface (MDI), including copying and pasting of cross sections and other data between HEC-RAS projects.

Workflows

CAD & GIS Integration

Integrate HEC-RAS directly with AutoCAD drawing files, Bentley MicroStation drawing files and ESRI ArcGIS map data.

2D & 3D Viewing and Editing

Shift seamlessly between 2D and 3D viewing perspectives to more clearly identify modeling issues and make changes.

Digital Terrain Cross Section Cutting

Extract HEC-RAS cross sections from 3D digital elevation terrain data.

Work Directly on the Map

Blend Google or Bing online maps and high-resolution aerial imagery files directly into the HEC-RAS model.

CAD & GIS Integration

Integrate HEC-RAS directly with AutoCAD drawing files, Bentley MicroStation drawing files and ESRI ArcGIS map data.

Digital Terrain Cross Section Cutting

Extract HEC-RAS cross sections from 3D digital elevation terrain data.

Floodplain and Floodway Mapping

Generate floodplain and floodway mapping from HEC-RAS results and 3D digital elevation terrain data.

1D and 2D Flow Models

Quickly build 1D and 2D HEC-RAS models using the provided CAD/GIS tools.

2D Mesh Generation and Refinement

Create either rectangular or adaptive meshes, depending upon the project requirements.

Complete land use coverage is provided for the USA at an approximate 100 x 100-foot grid cell size. This makes it extremely easy to assign Manning’s roughness values to the HEC-RAS model.

Included Land Use Coverage

Complete land use coverage is provided for the USA at an approx. 100 x 100-foot grid cell size.

Define bank stations, flow lengths, ineffective flow areas, conveyance obstructions, levees and other riverine modeling data from CAD and GIS data. Assign cross section Manning’s roughness using GIS polygons or orthophoto base map image processing.

Automated GIS Mapping Functions

Define bank stations, flow lengths, ineffective flow areas, conveyance obstructions, levees and other data.

Cloud-Based Mapping Services

Utilize world-wide high resolution 3D digital elevation terrain data from map services.

2D & 3D Viewing and Editing

Shift seamlessly between 2D and 3D viewing perspectives to more clearly identify modeling issues and make changes.

MDI Multiple Model Editing

Load, edit, and run multiple HEC-RAS models simultaneously.

More Accurate Models

Reduce time wasted with imprecise data. Easily integrate field collected data in varying formats.

Purpose-Built HEC-RAS Tools

HEC-RAS specific tools offer a more efficient way to create and analyze rivers, streams, bridges, culverts, inline structures, and more.

Stunning Visualizations

Create stunning visualizations directly from the software of different design alternatives to help better understand the impact of the design.
