What's new in WMS 10.1

Community Edition

A new Community Edition of WMS is now available beginning with v10.1. This is a fully functional version of WMS with the following limitations:

  1. Maximum number of sub-basins: 1
  2. Maximum number of GIS layers: 2
  3. Maximum number of map module coverages and attribute grids: 3
  4. Maximum number of terrain data layers (DEMs and TINs): 1
  5. Maximum number of storm drain pipes: 50

In addition, 2D scattered data, CAD data, 2D grid data, and 1D open-channel hydraulic data (HECRAS) are not available in the community edition but can be purchased with a license to WMS.

The community edition has an interface to HY12 that is completely free of charge. This means HY12 models with more than 50 pipes are supported as long as the other conditions of the community edition are met.

The community edition allows reading and viewing Rational, NSS, SWMM, EPANET, and other models that exceed these limits, but WMS does not allow saving changes to models that exceed the limits. This edition also allows building storm drain, water distribution, and sanitary sewer models that meet the above criteria as long as the maximum number of pipes is not exceeded. More information about the features available in each edition of WMS and how to purchase WMS can be found here.

EPANET Model Support

WMS 10.1 adds support for the EPANET model, a widely used water distribution model.

  • Read GIS data files
  • Map GIS attributes to the EPANET model attributes
  • Read and edit existing EPANET models

Improved EPA-SWMM Model Support

WMS 10.1 fully supports both sanitary sewer options and storm drain options associated with EPA-SWMM models.

  • Read GIS data files
  • Map GIS attributes to the EPA-SWMM model attributes
  • Read and edit existing EPA-SWMM models.

Improved HY12 Model Support

HY12 is an Federal Highway Administration (FHWA)-sponsored storm drain and hydrology model developed by Aquaveo. The Community edition of WMS 10.1 includes a completely free interface to HY12. There are four new tutorials that describe how to import and use various types of data into WMS to build an HY12 model. The HY12 tutorials may be viewed here.

WMS 10.1 includes a simplified interface to HY12 that makes developing an HY12 model much easier than before. The spreadsheet-like interface is similar to the EPA-SWMM and EPANET interfaces and much of the data can be transferred between HY12 and EPA-SWMM so data can be shared between these models.

In addition, a tool exists that allows editing link/node elevations in an HY12 model using a profile editor.

Time Series Data Calculator

Use the time series calculator in the Time Series Editor program to perform simple mathematical operations using time series data.

GSSHA Model Improvements

Several GSSHA model improvements have been made related to better calibration and renumbering streams.

Mine Water Balance Model (MWBM) Wizard

The MWBM wizard steps through the process of editing and modifying a GSSHA model based on changes to the terrain, land use, pumping stations, embankments, and other parameters in a mine model that is tracking sediment output from the mine.
