Welcome to CatchIS
Pesticide vulnerability modelling
Determining fate and behaviour of organic compounds
The CatchIS system employs a comprehensive suite of simulation screening models aimed at assessing the vulnerability of both surface and groundwaters to contamination by diffusely applied contaminants such as pesticides. The flow chart shown below provides an indication of which model you might wish to run based on the management issues being considered.
Typically CatchIS users will run a sequence of modelling approaches giving first a broad characterisation of the catchment, followed by more specific modelling focussing in on specific problem areas.
The models are selected from a simple menu interface:
"Top 10 Pesticides"
CatchIS has a suite of models available. The first allow you a predictive look at the likely top ten pesticides that will appear over the coming season in any catchment. Predictions are based on ADAS forecasts and can be selected either for Surface or Ground waters:
