Modelling the fate of pesticides in rivers

Modelling the fate of pesticides in rivers

The idea of this project is to develop a GIS-based management tool for crop protection agents in river basins.

The automatic tool consists of a module that allows simulation, Monte Carlo simulation, global sensitivity analysis, optimisation and allows reading experimental data. This module is written in Python and combines the PC Raster environment for spatial description (with different resolutions) with process models describing run-off, subsurface flow and pesticide behaviour.

A second module (feedback tool) communicates with the former by receiving its output in terms of quality with which the model is able to describe the collected data, hereby accounting for the objective defined by the user. If the latter is not met, a third module is called, namely the model selection module. The latter allows automatic model selection based on a decision tree that decides on the degree of complexity of the involved submodels. The constructed model is then fed back to the first module and so on. This iterative approach continues until the feedback tool confirms that an optimal model structure has been found for the objective defined and given the available data.
