Water Quality Analysis Simulation Program (WASP6/5)

Water Quality Analysis Simulation Program (WASP) is a generalized framework for modeling contaminant fate and transport in surface waters.   Based on the flexible compartment modeling approach, it can be applied in one, two or three dimensions and is designed to permit easy substitution of user- written routines into program structure. Problems studied using 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: Toxics, TOXI, combines kinetic structure with WASP transport structure and simple sediment balance algorithms to predict dissolved and sorbed chemical concentrations in the bed and overlying waters; dissolved oxygen /eutrophication, EUTRO, combines kinetic structure with WASP transport structure to predict DO and phytoplankton dynamics affected by nutrients and organic material.   Detailed WASP model description is available. WASP's input requirements and output description too large to be described here. Please download and install model documentation for detailed data requirements.

Hold down "F5" key during the booting process to bypass current AUTOEXEC.BAT and CONFIG.SYS settings temporarily. Run WASP installation program (=INSTALWP.EXE). Of course, reboot again when the WASP installation completes.
