The WMS software development team is excited about the release of WMS 10.0! This page lists the exciting new features that have been added to WMS 10.0.

What's new in WMS 10.0

GSSHA Interface and Model Updates

Model Calibration Updates

The newest version of GSSHA supports PEST-style automated calibration methods. WMS 10.0 has an interface to these automated calibration methods in GSSHA. More information about automated calibration in GSSHA using WMS 10.0 is located here.

Depth Varying Overland Flow Roughness

The newest version of GSSHA has a mapping table that supports a depth-varying overland flow roughness exponent. This parameter is used in addition to the roughness mapping table. Without the addition of this table, a default exponent of 0.0 is used, which means the roughness does not change with overland flow depth.

Link/Node-Specific Overbank and Backwater Options

GSSHA previously had two options that could be defined globally. The first option, the overbank flow option (OVERBANK_FLOW), increases the level of connection between the overland flow and the channel in the 1D hydraulic model by allowing water to spill from the channel back onto the overland flow plane. If the second option, the overland backwater option (OVERLAND_BACKWATER), is turned on, flow from the overland flow model to the channel in the 1D hydraulic model is restricted if the elevation of the water in the channel exceeds the overland cell elevation. This option can now be defined at each of the arcs (links) in your GSSHA model in the GSSHA arc properties dialog. If this option is defined for one of the arcs, the global option is turned off.

Storm and Tile Drain Interface Tools

WMS 10.0 contains many new GSSHA storm and tile drain interface tools. A detailed description of all the tools available here.

New GSSHA Tutorial

Several of the GSSHA tutorials have been updated to reflect changes to GSSHA and its interface, especially the storm and tile drain tutorial and the calibration tutorial.

Also, a new tutorial has been added to the list of WMS tutorials under the Spatial modeling section. This tutorial describes how to convert an HMS model to a GSSHA model using simple, easy-to-follow steps from the WMS interface.


Hydrologic Modeling System (HEC-HMS) 4.0 Support

Added capability to define snow melt, deficit and constant, and other gridded parameters for ModClark Grid

New HMS Tutorial


National Streamflow Statistics (NSS) 6.0 Support


EPA-SWMM Updates

Sanitary Sewer Modeling Options

Sanitary sewer coverage Define Diurnal curve dialog, import curve names, and assign curves to nodes/manholes, export to SWMM Import infiltration and domestic flows from shapefiles and export to SWMM Import a peaking factor for the domestic flows and export to SWMM Import SWMM 5 model with sanitary sewer options into WMS and export to shapefile


SWMM 5.1 Support


Additional Web Services
