Virtual Beach is a decision support tool that facilitates the development of statistical models of water quality at site-specific locations. It allows users to estimate any general response variable, such as microbial or blue-green algae concentrations, using commonly measured environmental data. Modeled water quality estimates can then be used to inform site-based management decisions, such as issuing swimming or shellfish harvesting advisories. This webinar will feature a live demonstration of the new version of Virtual Beach.
