The Cascade Drift Model: first results of a realistic study on regional pesticide deposition

Research output: Chapter in Book/Report/Conference proceedingConference paper

Abstract

The Cascade Project describes the modelling of spray drift and pesticide fate for a network of interconnected water bodies in a rural area. A first part of the project, the Cascade Drift Model, models the spatial and temporal distribution of deposits of spray drift onto surface waters in the mentioned rural area. Deposits of spray drift are computed using a generic drift function, derived by multiple linear regression from a large set of random scenarios computed by the IDEFICS spray drift model. The Cascade Drift Model takes into account the adjustment of parameters such as day-to-day weather conditions, water management measures (regulating water levels), and the choices a farmer has to make regarding spray application. The model enables a realistic evaluation of drift deposits onto surface waters in a certain region during a season and the effects of various measures affecting drift deposition. Results will be used subsequently in the next part of the project, the Cascade Fate Model, which models the fate of pesticides in water bodies. First computations give an insight into the variations occurring under varying conditions due to the geometry of the investigated area and changing weather conditions
