SWASH is an acronym for Surface WAter Scenarios Help and is an overall user-friendly shell, managing the communication and data transfer between four models involved in Step 3 calculations for the FOCUS Surface Water Scenarios. These scenarios have been developed as part of the EU evaluation process under 91/414/EEC (See EFSA Website). Spray drift, and either drainage or run-off are the routes of pesticide entry into surface waters. Using spray-drift deposition tables and the MACRO, PRZM and TOXSWA models the exposure concentrations in surface waters can be assessed. To carry out the FOCUS Surface Water Scenarios, a drift assessment tool and two pesticide fate models have to be run in the correct sequence.

Status A
SWASH (FOCUS_SWASH version 5.3) is in compliance with the Status A level for models and databases of Wageningen UR, i.e. conform to requirements for software robustness, software and model performance tests, documentation of the concepts and user documentation. Read more (Dutch).
