A modular catchment model to support regulatory landscape-scale aquatic risk assessment

Landscape modelling is key for future environmental risk assessment (ERA) of aquatic ecosystems related to plant protection products (PPP).

Landscape modelling is key for future environmental risk assessment (ERA) of aquatic ecosystems related to plant protection products (PPP) (EFSA, 2013). Currently, field scale models are used at lower tiers to simulate transport and fate of PPP in edge-of-field surface waters due to runoff, drainage and spray drift deposition. These models predict the exposure concentration in predefined water bodies, i.e. streams, ditches and ponds. In a higher tier approach, a new generation of tools should provide more realistically concentration patterns for higher tier risk assessment.
