Comprehensive CRS Support
A more complete and comprehensive coordinate reference system (CRS) support has been implemented. Many local and regional CRS projections have been added. In addition, the user interaction in assigning CRS projections has been improved.
Improved Display of CRS Projection Details
For a selected coordinate reference system (CRS), the units are clearly shown in meters, international feet, and US survey feet.
Reading CRS from AutoCAD Civil 3D Drawings
The software will now determine the coordinate reference system (CRS) from loaded AutoCAD Civil 3D drawings. This speeds up the process of loading CAD drawings into the software by not having to manually assign the CRS to the loaded CAD drawing.
Local CRS Support
When working with HEC-RAS models and project data that are not defined relative to any particular map coordinate reference system (CRS), but rather to a local CRS, the software now provides a Local CRS in the listing of available Custom CRSs. This allows the associated data to be pulled together on the same location within the Map View.
Additional Base Maps
Additional base maps and an improved USGS topographic map have been added.
Assign Manning’s Roughness using CAD Polygons
The Assign Manning’s Data command has been extended to support AutoCAD and MicroStation drawing files containing polygons. This allows the user to draw polygons on top of an orthophoto within AutoCAD or MicroStation, representing different roughness subareas. A default left overbank, channel, and right overbank roughness can be defined. The polygon’s elevation should be assigned 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.
Additional Node Name Support
The software will now display the node names on the Map View underneath the river station IDs. In addition, the user can perform table editing of the node names using the Edit River Stations & Node Names command.
HEC-RAS Project Description Memo Field Size Increased
The HEC-RAS Project Description memo field, contained within the Info backstage page, is increased in size to allow the user to see more content and to store larger project descriptions.
Compute Steady-Current Scenario dialog
The Compute Steady – Current Scenario dialog box now allows the user to select specific profiles to analyze, rather than analyzing all of the defined profiles. For example, the user may have the 2-Year, 5-Year, 10-Year, 25-Year, 50-Year, and 100-Year profiles defined. This new implementation allows the user to select from the list of profiles which profile(s) to analyze.
Resizable Data Dialog Boxes
All data dialog boxes (i.e., Cross Section Data, Bridge & Culvert Data, Inline Structure Data, Lateral Structure Data, Storage Area Data, and Storage Area Connection Data) are horizontally resizable. The user can resize the dialog box by grabbing and dragging the left or right side of the dialog box to make the dialog box narrower or wider.
Scour Input Data Saving
Previously, when the user switched between projects, any defined scour data within the HEC-RAS Scour Calculator was lost. In addition, after the user closed the project, the scour data was lost. The software now remembers this data throughout the life of the project.
Flood Maps for Geographic CRS Elevation Grids
The software can now generate flood map results for elevation grids that are defined in a geographic coordinate reference system (CRS) projection.
Generate Contours with Assigned Z Elevation
When generating contours using the Generate Contours command, the resultant 3D polyline shapefile has assigned Z elevation values in addition to an elevation attribute.
Georeference Cross Sections Command Improvements
Additional functionality has been added to the Georeference Cross Sections command. The software can now re-extract the ground terrain after georeferencing the cross section as well as recompute the cross section flow lengths.
Assign Ineffective Flow Areas Command Improvements
Various assignment improvements have been made to the Assign Ineffective Flow Areas command.
Assign Conveyance Obstructions Command Improvements
Various assignment improvements have been made to the Assign Conveyance Obstructions command.
FEMA Floodplain Encroachments Command Improvements
The Floodplain Encroachments command has been improved, making the dialog box more compact and also displaying the volume between cross sections for each profile in order to estimate the loss of storage volume due to the defined floodplain encroachments.
Assign Flow Lengths Command at Junctions
Using the Assign Flow Lengths command, the software will now compute the flow lengths at river reach junctions.
HEC-RAS Project Archive Improvements
When archiving a HEC-RAS project as a ZIP file, if the HEC-RAS analysis has been performed and the user has requested that the analysis results be stored in the archive ZIP file, the software will automatically include the HEC-RAS ASCII output report in the archive.
Improved Compression of Archived Projects
Three levels of ZIP compression are provided when archiving projects: Fast, Normal, and Best. Choosing “Best” will create the smallest ZIP file, but may take a longer time. In addition, the software will remember what ZIP compression level was last selected when creating an archive.
Increased Base Map Resolution for Exported HEC-RAS Models
When exporting the HEC-RAS model to AutoCAD, MicroStation or to the US Army Corps of Engineers software, the user can now specify the resolution to be used for the exported base map. This exported base map is stored as a pyramid image file with multiple resolutions, depending upon the zoom factor, using the JPEG2000 file format.
Installation Support for Foreign Language Computers
The software now supports installation of the software on foreign language computers.
Download Update without Installing
The software update can now be downloaded without requiring the installation to happen. This is useful when the IT staff wants to download a single update and then roll the update out across the local area network.
Optimized Loading of AutoCAD and MicroStation Drawings
Loading of AutoCAD and MicroStation drawing files have been significantly sped up.
Sorting of CAD Layers by Name and Visibility Status
The user can now sort the CAD layers within the CAD Properties dialog box based upon the layer name and visibility status. This makes it easier to see which layers are turned on or off.
CAD Drawing XREFs
The software now supports AutoCAD and MicroStation drawing files that contain external references to other drawing files. Included in the CAD Properties dialog box is a panel that allows the user to see the various externally referenced drawings and their associated details.
AutoCAD and MicroStation Line Style Support
The software now supports AutoCAD and MicroStation line styles.
AutoCAD and MicroStation Corrupt Drawing File Handling
The software will now detect corrupted AutoCAD and MicroStation drawing files and provide instructions on how to repair the drawing files if it is unable to load the files.
Defined Tab Order in Dialog Box Fields
The user can navigate between data input fields within the dialog boxes using Tab and Shift Tab keypresses.
Improved Georeferencing of Imported Images and PDFs
The user can unlock the layer containing an imported aerial image or PDF and can then manually drag and rotate the image or PDF to precisely locate where it should reside.
Improved Color Shading of Elevation Grids
The color shading of elevation grids has been greatly improved using a new hill shading algorithm in order for the user to clearly see the elevation relief contained in the terrain.
Improved Merge DEMs Command
The Merge DEMs command has been enhanced to support more complex DEM merging operations. The user can specify the merge order when working with multiple DEMs, as well as inform the software to select the highest elevation for the overlap area.
Rubber-banding while Digitizing in Cross Section Plots
While measuring distances and drawing polylines in the dialog box cross section plots, the software will now show a rubber-banding line so that it is easier for the user to see what is being measured or created.
Extended Conflate Command Support
The Conflate command has been added to roadway crossings, inline structures, and lateral structures. This allows the user to quickly assign survey elevation points to a structure. This command allows survey point data to be merged into HEC-RAS structural element. This command works with XYZ point files, AutoCAD drawings, and GIS point shapefiles. The user can define a buffer distance for the structural element and the software will automatically snap point data to the element. Snapping of survey data can be either perpendicular to the element or parallel to the river reach polyline. The user can restrict merging of survey data to channel only, left or right overbanks, both overbanks, or the entire structure cross section.
Uniform Scale for Roadway Crossing Plot
When plotting the upstream and downstream face cross sections at a roadway crossing, the software provides an option to use the same horizontal and vertical scale. This is useful when trying to compare the relative size of elements at both sides of the roadway crossing.
More Seamless Transition from and to 3D View
When transitioning between the 2D and 3D views, the software does a better job of maintaining a consistent field of view of the project data.
Copy Data Explorer Contents
The software allows the user to copy the contents of the Data Explorer to the clipboard. This is useful when the user wants to place the contents into a MS Word document or Excel spreadsheet.
