3. DESCRIPTION OF PROGRAM OR FUNCTION

DISPERS computes the fate of routinely or accidentally released radionuclides in surface water and groundwater.

4. METHOD OF SOLUTION

The mathematical models in DISPERS are straightforward simulations of dispersion with constant coefficients and, in general, simple geometries. The SSTUBE and TUBE programs are useful for two-dimensional dispersion of a continuous source into a river after steady state has been attained. The RIVLAK program also applies to dispersion in a river, but the source may be steady or unsteady. GROUND is used for calculating the dispersion in a three-dimensional aquifer and is most useful for determining the concentration at wells dowgradient of a source released from a vertical plane. GRDFLX provides the same function but it considers a horizontal area source.
