WMS:What's new in WMS version 8.2

The WMS software development team is excited about the release of WMS 8.2! This page lists the exciting new features that have been added to WMS 8.2.

Model Enhancements

Hydrologic Modeling

---

Calibration and Batch Mode Processes

Support of calibration and batch mode processes (stochastic modeling) in the GSSHA interface

Using WMS 8.2, you can run GSSHA in calibration mode to determine optimum parameters or in batch mode to run using a range of input values.

Improved Stream Smoothing and Grid Matching Capabilities

Improved stream model checker, better stream visualization, stream adjustment to match grid, and improved stream smoothing

The hydrologic modeling wizard has been improved in WMS 8.2 to allow for editing stream elevations before creating a 2D grid. When the 2D grid is generated, the grid cell elevations are set to match the stream elevations. Matching up these elevations reduces the chance for errors in running your GSSHA model when stream routing is defined.

Example of Multiple Scenarios in the Project Explorer

Ability to create multiple GSSHA scenarios (multiple GSSHA job controls, sets of index maps, mapping tables, solutions, etc.)

Multiple scenarios, such pre-development and post-development conditions, can be defined in a single instance of WMS. Each of these scenarios can be run and the results from each scenario can be compared.

Groundwater and Sediment Transport Example

Support of wetlands, sediment transport, and groundwater/surfacewater interaction routines in GSSHA

WMS 8.2 contains full support for wetland, sediment transport, and groundwater/surfacewater interaction capabilities in GSSHA. Tutorials for each of these capabilities are available on gsshawiki.com.

Example Roadway Embankment

Improved ability for defining embankment arcs

WMS 8.2 has improved ability for defining embankment arcs and running GSSHA embankment routines that was not available in previous version of WMS.

Hydraulic Modeling

HEC-RAS 4.0 Sediment Transport

Support of HEC-RAS 4.0 and sediment transport

WMS 8.2 contains support for the latest version of HEC-RAS, version 4.0, which has sediment transport capabilities.

General Enhancements

Web Data Service Options

Improved web service client tools

WMS 8.2 Includes all types of NED and SRTM elevation data downloads, Terraserver images, and a web catalog that allows you to download any type of data if the data is available. These data sets can be downloaded directly from WMS and from the hydrologic modeling wizard. In WMS 8.2, practically all of the data required for a hydrologic study can be downloaded directly from WMS for any location in the world.

Animation Exported to Google Earth

Output animated KMZ files to Google Earth

One of the results from running a GSSHA model is water depth at any location of your watershed for any time during your simulation. With WMS 8.2, you can export an animation of the water depth contours and any other parameter that is computed in GSSHA to a file that can be read by Google Earth. This capability is great for presentations of GSSHA model results.

Zonal Classification

Dataset zonal classification

Using WMS 8.2, you can combine datasets such as erosion and deposition to view areas of low erosion and high deposition or high erosion and low deposition based on certain criteria. You can view the results of these queries throughout your watershed.
