PESTAN - pesticide transport model; transport of organic solutes through the vadose zone to ground water

PESTAN Categories: flow models - unsaturated zone, solute transport models - unsaturated zone
 

PESTAN Overview

PESTAN, Pesticide Transport, is a U.S. EPA program for evaluating the transport of organic solutes through the vadose zone to ground water. PESTAN uses an analytical solution to calculate organic movement based on a linear isotherm, first-order degradation and hydrodynamic dispersion. Input data includes water solubility, infiltration rate, bulk density, sorption constant, degradation rates, saturated water content, characteristic curve coefficient, saturated hydraulic conductivity and dispersion coefficient.

The new WHI UnSat Suite includes a powerful graphical user interface for the PESTAN model. Click here for information.
