USGS Workshop Video Training

Workshops led by Wisconsin Sea Grant and the USGS Wisconsin Water Science Center titled Developing Predictive Models for your Beach: Hands-on Training, were recorded and are available below. The full training for building a complete model in Virtual Beach takes 10-12 hours.
