RiverNET is the leading software that incorporates HEC-RAS and HEC-2 in AutoCAD. It includes a range of features and capabilities that automates HEC-RAS modeling tasks. Automatic cross section cutting, mapping of roughness values and bank station locations, floodplain mapping, floodway determination, bridges, culverts, and more. RiverNET is used by over 2,500 organizations worldwide.

Summary of New Features (and more coming soon...)

U.S. Army Corps of Engineers HEC-RAS

Full support of HEC-RAS version 4.0, allowing the user complete flexibility in supporting, importing, and exporting of HEC-RAS models without any loss of data.

Floodplain and Floodway Mapping

Increased speed in floodplain and floodway mapping, along with additional options added.

Automated Cross Section Cutting

This new command will automatically construct cross sections along the river from a selected river alignment line drawn on the topo map. In addition, optional left and right overbank station alignment lines, as well as left and right overbank flow length alignment lines can be used to define this data.

Improved Cross Section Cutting

Additional and enhanced manual cross section cutting commands have been added, allowing the user to work with a variety of 2D and 3D digital terrain data. Additional methods for extracting cross section geometry from polylines and cross section alignments. Improvements to constructing cross sections from merging multiple source data. Easier manual editing of cross section geometry. Support for spline contour topo maps added.

Automated Overbank Stationing

This new command causes overbank stations to be "burned into" the existing river cross sections using left and right overbank station alignment lines drawn on the topo map.

Automated Flow Lengths

This new command causes the left overbank, channel, and right overbank flow lengths to automatically be computed based upon alignment lines drawn on the topo map. This command is extremely useful, by automatically updating the flow lengths as new cross sections are inserted into the existing model, and when revising channel and overbank flow lengths based upon the computed extent of the overbank flooding.

Automated Assign Manning’s Roughness

This new command allows the Manning's roughness to be "burned into" the existing river cross sections using roughness polygons drawn on the topo map. This allows the user to draw polygons on top of an orthophoto, representing different roughness subareas. A default left overbank, channel, and right overbank roughness can be defined. The polygon's elevation needs to be set equal to the associated Manning's roughness. It is important that the drawing's decimal precision be set high enough to allow enough significant digits in assigning the polygon elevations to match that of the associated Manning's roughness.

Automated Ineffective Flow Areas

This new command allows ineffective flow areas to be automatically mapped from the topo map to the cross section data. Drawing polygons as ineffective flow areas, this data can be "burned into" the existing river cross sections.

Automated Conveyance Obstructions

Similar to the Automated Ineffective Flow Areas command, this new command allows conveyance obstruction areas to be automatically mapped from the topo map to the cross section data. Drawing polygons as conveyance obstruction areas, this data can be "burned into" the existing river cross sections.

Automated Assign Levees

This new command allows levees to be automatically mapped from the topo map to the cross section data. Drawing alignment lines representing the levee stations along the river, levees are placed on the cross sections at the intersecting ground elevation, maximum cross section elevation, or user-specified elevation.

Junctions, Tributaries, and Split Flow

Full support for junctions, tributary flow, and split flow has been added. Automatic computation of diverted discharge (i.e., split flow optimization) at split flow locations has been added.

Bridges and Culverts

A greatly improved Opening Definitions dialog has been added, including better support for multiple bridges and culverts at a single roadway crossing. Improved Bridge Methodology dialog and Piers dialog added.

Internal Bridge Cross Sections

Support for internal bridge cross section geometry data has been added. This allows the user more control over how the bridge opening geometry and roughness is defined.

Bridge Scour Computations

Improvements to Scour Analysis dialog and Scour Analysis Report has been added.

Inline Weir Structures

An improved Inline Weir dialog has been added, making it easier for users to define gated spillways and inline weir structures.

Dockable Toolbar

An improved dockable toolbar has been provided, with additional commands added to assist the user.

Audit Database Command

This new command allows the user to inspect the integrity of the RiverNET database. If a problem in the database is encountered, RiverNET will attempt to repair the problem and recover the missing data. Otherwise, the offending database entity is purged from the database and the remainder of the database is checked.

Enhanced Crash Reporting

Improvements to crash reporting added, allowing our software development team to better determine the reason for any crashes that occur during the use of RiverNET.

Improved Installation Program

Support for silent install, allowing network administrators to more easily setup new workstations. Digital signature added. Easier installations of hardware lock drivers for Network Server Version. For computers with multiple versions of AutoCAD installed on them, the user is able to select the version of AutoCAD to install the RiverNET software for.
