Evaluation of the applicabillity of the SWAP-ANIMO model for simulating nutrient loading of surface water in peat land area : Calibration, validation, and system and scenario analysis for an experimental site in the Vlietpolder

Research output: Book/ReportReportProfessional

Abstract

The applicability of the SWAP-ANIMO model for simulating nutrient loading of surface water in a peat land area was tested against results of an experimental plot on a peat pasture in the Vlietpolder in the West of the Netherlands. The model was calibrated against a part of these results and validated against another part. It was concluded that the model is reasonably well able to simulate nutrient loading, because it includes all major processes. It is recommended to add a second pool of dissolved organic matter, to be able to distinguish between labile (fresh) and more stable (peat) organic matter. According to the simulation results, dairy farming contributed for 25-50% to nutrient loading, depending on nutrient (N or P) and weather year.
