Abstract:

The WASP5 system consists of two stand alone computer programs, DYNHYD5 and WASP5,that can be run in conjunction or separately. The hydrodynamics program, DYNHYD5, simulates the movement of water while the water quality program, WASP5, simulates the movement and interaction of pollutants within the water. While DYNHYD5 is delivered with WASP5, other hydrodynamic programs have also been linked with WASP. RIVMOD handles unsteady flow in one-dimensional rivers, while SED3D handles unsteady, three-dimensional flow in lakes and estuaries. WASP5 is supplied with two kinetic sub models to simulate two of the major classes of water quality problems: conventional pollution (involving dissolved oxygen, biochemical oxygen demand, nutrients and eutrophication) and toxic pollution (involving organic chemicals, metals, and sediment). The linkage of either sub model with the WASP5 program gives the models EUTRO5 and TOXI5, respectively. In most instances, TOXI5 is used for tracers by specifying no decay. The basic principle of both the hydrodynamics and water quality program is the conservation of mass. The water volume and water quality constituent masses being studied are tracked and accounted for over time and space using a series of mass balancing equations. The hydrodynamics program also conserves momentum, or energy, throughout time and space. ( Source: http://www.cee.odu.edu/cee/model/wsp_desc.html) Actual Version is: 6.1
