Technical Documentation of PestSurf, a Model describing Fate and Transport of Pesticides in Surface Water for Danish Conditions

1 Technical Background Information

PestSurf is a model for estimation of transport of active substance to streams and ponds. It is build with the model systems MIKE SHE (Refsgaard and Storm, 1995) and MIKE 11 (DHI, 1997). The two model systems has been implemented on two Danish catchments (Styczen et al., 2004a), and these calibrations form the base for the scenarios (Styczen et al., 2004b) that can be simulated by PestSurf. The PestSurf interface allows the user to select a pond or a stream in either of the two scenario catchments, and parameterise an active substance and/or a metabolite.

This Documentation concentrates on the differences between the models included in "PestSurf" and the standard models MIKE SHE and MIKE 11. It is not the intention to repeat the information already available in the User manuals of MIKE SHE and MIKE 11. These Documents will be made available to the Environmental Protection Agency together with the model. The relevant Documents and the topics of particular relevance to "PestSurf" are listed in Table 1.1.

Table 1.1 Documentation available in MIKE SHE and MIKE 11 User Manuals.
