Hydrologic and Hydraulic Modeling with WMS
In this hands-on, application oriented training course you will learn how to use automated hydrology and hydraulics tools in the Watershed Modeling System (WMS). Upon completion of the course, you will know how to obtain and use GIS data and digital terrain data in watershed modeling, floodplain analysis and mapping. You will also learn the software tools needed to process this data, create numerical models, and generate digital watershed and flood maps.
This course will provide practical training on the use of software tools to aid in the hydrologic and hydraulic analysis and floodplain delineation. The use of the Watershed Modeling System (WMS) for watershed runoff analysis, coupled with channel hydraulics, will be the focus of the course. An integrated, GIS-based approach to hydrology, hydraulics, and mapping will be presented step-by-step, with computer workshops, to allow participants to implement the concepts presented. Participants will gain experience in using the software to create 1) GIS-based hydrologic simulations using HEC-HMS and 2) hydraulic simulations (HEC-RAS) from the hydrologic model results and GIS data. The final step will be using WMS to interpret hydraulic model results in conjunction with digital elevation data to create flood extent maps, flood inundation maps, flood depth maps, and flood impact maps.
Automated watershed delineation will be covered in detail along with application of GIS data layers to compute common hydrologic and hydraulic modeling parameters (Curve Number, Manning’s roughness, Green & Ampt parameters, travel time, etc.)
Since this course will focus more on application than on theory, a knowledge of basic rainfall/runoff modeling principles is recommended, but not required. The training course will be taught by hydrologic and hydraulic modeling consultants at Aquaveo and will use the latest version of WMS.

Training Attendee Cancellation Policy
Participants may be required to provide their own computer with the following specifications:
- Windows XP, Vista, 7 or 8 operating system
- 1 GB RAM (2 GB recommended)
- CPU: WMS software is CPU intensive. Some models and utilities can take advantage of multiple processor cores simultaneously.
- Graphics Card: For all display features to be enabled, OpenGL 1.5 or higher must be supported. The use of a dedicated graphics card is strongly recommended. Integrated graphics can result in significantly reduced performance and may not support some visualization features.
- 1024x768 resolution (1280x1024 or higher recommended)
