WHI UnSat Suite

231 Waterloo Hydrogeologic UnSat Suite v2.2.0.2 The WHI UnSat Suite combines three popular unsaturated zone models in a powerful new graphical environment specifically designed for simulating one-dimensional groundwater flow and contaminant transport through the unsaturated zone. These models are: SESOIL - a popular US EPA model which is capable of simultaneously modeling water transport, sediment transport and pollutant fate. SESOIL is widely used by consultants and state regulatory agencies as a screening tool to assess contaminant fate and transport for regulatory requirements. PESTAN (PESTicide ANalytical) - a model for assessments of groundwater contamination by pesticides used in agricultural practice. VS2DT (Variably Saturated 2D flow and Transport) - a finite difference numerical model for determining the fate of agricultural chemicals, landfill leachate, and accidental chemical
