WASP: Water Quality Analysis Simulation Program

DESCRIPTION

Water Quality Analysis Simulation Program, WASP5 is a generalized framework for modeling water quality and contaminant fate and transport in surface waters. Based on the flexible compartment modeling approach, WASP can be applied in one, two, or three dimensions. WASP is designed to permit easy substitution of user-written routines into the program structure.

Problems that have been studied using the WASP framework include biochemical oxygen demand and dissolved oxygen dynamics, nutrients and eutrophication, bacterial contamination, and organic chemical and heavy metal contamination.

Two WASP models are provided with WASP5. The toxics WASP model, TOXI5, combines a kinetic structure adapted from EXAMS2 with the WASP5 transport structure and simple sediment balance algorithms to predict dissolved and sorbed chemical concentrations in the bed and overlying waters. The dissolved oxygen/eutrophication WASP model EUTRO5 combines a kinetic structure adapted from the Potomac Eutrophication Model with the WASP5 transport structure to predict DO and phytoplankton dynamics affected by nutrients and organic material. WASP has been used to simulate the water quality and pollutant fate for a variety of aquatic systems. It is used primarily to investigate the water quality response to management actions, primarily point and nonpoint source load reduction. It is presently being distributed by SEAM and its status is "in-use." The technical contact is Robert Ambrose.
