The WMS software development team is excited about the release of WMS 8.5! This page lists the exciting new features that have been added to WMS 8.5.

What's new in WMS 8.5

The GSSHA model is a 2D watershed model that includes 1D hydraulic modeling, groundwater modeling, and other advanced watershed modeling components.

Updated Interfaces

The NSS (National Streamflow Statistics) interface has been updated to use the latest NSS database. The MODRAT interface has also been updated. Renumbering has been improved in the MODRAT interface and several issues have been fixed. Several new features and enhancements have been added to the GSSHA interface. First, the storm and tile drain modeling capability of GSSHA has been improved by adding the capability to add multiple pipes in a "superlink", which represents a network of pipes in GSSHA. The algorithm for determining embankments has also been reworked to make the algorithm more efficient and more accurate. The GSSHA tutorials have also been updated and improved to include the latest enhancements in the GSSHA code. Also, GSSHA itself has been reworked to make the program more stable.

The HY-12 model is a storm drain model developed by Aquaveo and the FHWA (US Federal Highway Administration).

FHWA HY-12 Storm Drain Modeling

WMS includes an interface to FHWA's HY-12 storm drain modeling program. This interface allows you to create a storm drain layout and assign rational method computations, curbs and gutters, access holes, pipes, channels, and other storm drain network features to the storm drain layout. Much of the data can be computed automatically using the interface, and other data values can be entered in the easy-to-use windows. The other storm drain modeling interfaces, including the SWMM and xp-swmm interfaces, have also been upgraded to make your model easier to build and maintain.
