Résumé
- A large temporal variability in water quality of Dutch brooks makes it difficult to determine their water quality status. Consequently, it often is impossible to identify the effects of measures that should have improved the water quality. For these reasons we tested new measurement techniques that account for dynamics in water quality en we have formulated new model concepts that can describe and predict temporal variations in water quality. For The Hupsel Brook in the Netherlands we demonstrated how these new measurement and model techniques allow us to relate the reduction in nutrient usage by farmers during the past 30 years to changes in the dynamics of water quality. Hence, this research contributes to the knowledge that is needed for a sustainable management of ground- and surface water resources of Dutch brooks.
