| Description | PRZM2 links two subordinate models in order to predict pesticide fate and transport through the crop root zone, and the unsaturated zone. PRZM is a 1D finite-difference model which accounts for pesticide fate and transport in the crop root zone including: soil temperature simulation, volatilisation and vapour phase transport in soils, irrigation simulation, microbial transformation, and a method of characteristics (MOC) algorithm to eliminate numerical dispersion, parent compound and up to two daughter species. VADOFT is a 1D finite-element code which solves the Richard's equation for flow in the unsaturated zone with the constitutive relationships between pressure, water content, and hydraulic conductivity. Simulates the fate and transport of two parent and two daughter products. In order to perform exposure assessments, the code is equipped with a Monte Carlo pre- and post-processor. Program data input is interactive and the program produces tabular output to files. |
