The catchment system can be simulated as the sum of multiple field-scale processes. Pesticide concentrations in stream flow were driven by field-scale processes. In-stream processes had little effect on simulations. Uncertainties in rain gauge recording affected the simulation of low-flow periods. SPIDER simulates important lateral flow losses that can occur when drains are not flowing.
