GeoHECHMS (February 24, 2022 Release)
EPA and USGS Stream Gages
The software can now display both EPA and USGS stream gage locations on the Map View. Clicking on a specific stream gage location will display detail about the gage in the Data Explorer.
2DM File Format Support
The software can import the Aquaveo SMS application’s .2dm mesh geometry files. To convert the .2dm mesh to an elevation grid see the Generate Terrain Command knowledge base article.
Intelligent Ordering of Entries
When working with different storms and scenarios, the user will commonly refer to an entry as a “10yr Storm”, “25yr Storm”, “50yr Storm”, “100yr Storm”. Previously, when these names were used to describe meteorological data or scenarios, the software would list the entries in alphanumerical order as follows:
This ordering system is consistent with the methodology used by Microsoft Excel and Microsoft Word. However, a civil engineer recognizes that this system does not make sense from a storm frequency perspective. The software now intelligently orders the entries as follows:
Land Use, Impervious, and Soil Map Data on Mirrored Azure Webservices
The land use data, impervious data, and soil map data for the US and other parts of the world are now mirrored on Azure webservices. The software will automatically recognize when the main webservice (e.g., USGS, USDA, NOAA, etc.) server is not available and the software then instantly fails over to a mirrored webservice server on Microsoft Azure managed by CivilGEO.
Subbasin Table Edit Command
The Subbasin Table Edit command allows the user to edit the physical and hydrologic parameters for all subbasins in a single data grid. Selecting this command displays a modeless dialog box that contains data columns for all the common subbasin parameters. The user can interactively select subbasins on the Map View and the current row indicator will be shown in the data grid. The user can then actively edit the data contained in the data grid or copy the data to a Microsoft Excel spreadsheet.
Reshape Subbasins Command
The new Reshape Subbasins command allows the user to easily and quickly cleanup the watershed boundary for a single subbasin or between two adjacent subbasins.
Split Subbasins Command
The new Split Subbasins command allows the user to easily and quickly split one or more subbasins with use of a drawn polyline.
Merge Subbasins Command
The new Merge Subbasins command allows the user to easily and quickly merge two or more adjacent subbasins into a single subbasin.
Measure Plot Command
The user can use the new Measure Plot command within the graphical plots to measure the time offset and discharge difference between hydrograph peaks.
Many users find that using an external keyboard with keyboard shortcuts helps them work more efficiently. Press Ctrl+Period (.) to display a dialog box listing the currently assigned keyboard shortcuts. The user can add, remove, and edit keyboard shortcuts, as well as export and import the keyboard shortcut file to allow access to other users.
Import Pipe Network Command
Using the Import Pipe Network command, an AutoCAD Civil 3D pipe and manhole network can now be imported into the software using a LandXML file format.
Export Pipe Network Command
Using the Export Pipe Network command, an AutoCAD Civil 3D pipe and manhole network can now be exported using a LandXML file format. The junctions are exported as manholes, the reaches are exported as pipes, and the subbasins are exported as parcels.
Project Options – Decimal Digit Precision
From the Options backstage page, the user can set the decimal digit precision for most input data, including:
- Percent Impervious
- Curve Number
- Time of Concentration/Lag Time
- And many more…
