UK Drainflow modelling

 

 

This tool proves to be a significant step forward with regard to harmonising the modelling submitted by different applicants, however, use of the tool is not always easy. Firstly, users will need access to a 32-bit PC or virtual machine, as the tool uses MACRO 4.3, which historically runs on 32-bit computers. CRD is planning to develop a future update that uses one of the later MACRO 5 versions, though this may take some time. Secondly, some risk assessments can require a fourth weather scenario to be modelled (e.g. when assessing applications to maize and grassland) and this is not currently covered by the tool being developed by CRD.

 

Previously, the assessment required spatial statistics for calculating the overall percentage of exceedances: Geographical data in SEISMIC (NSRI) or alternative GIS software was used to calculate the crop distribution across the drained soil types in the UK. It is no longer required to present the spatial statistics. 

• Fully automated drainflow assessment from input of basic substance properties to creating the reporting tables
• Dedicated 32-bit server to speed up model simulations
• Cropping statistics are included for all crops listed in SEISMIC
• Covers 20 UK scenarios (CRD approved), including the very wet weather locations

The automated process allows fast standard assessments and reporting. Quick explorative simulations can be performed for new substances or for optimising the GAP. When required, the standard higher-tier assessments are further refined, specific for the product’s need.
