Mathematical Model

WASH123D is a first-principle, physics-based computer model that has been developed, with support from the U.S. EPA STAR program, for modeling hydrology, hydraulics, and water quality at various temporal and spatial scales over a watershed. The system components of the watershed may include river/stream/canal network, overland regime, subsurface media, and

control and management structures including weirs, gates, culverts, pumps, storage ponds, levees, etc.

Most recently WASH123D has been applied to the Wekiva River Springshed (click the animation for spring flow) in Central Florida and storage value evaluation in Northern Palm Beach County by UCF investigators. It has been used by the Army Corps of Engineers to design a small-scale canal spreader and to study a middle-scale Biscayne Bay wetland restoration, and is currently being used to construct a large-scale Regional Engineering Model for Ecosystem Restoration (REMER), which covers a large portion of Central-South Florida south of the Okeechobee Lake.
