Testing a low-complexity spatially distributed model to simulate the intra-annual dynamics of soil erosion and sediment delivery

Erosion models simulating the intra-annual effects of hydrometeorological drivers and disturbances (e.g. vegetation clearcutting, tillage events, wildfires) need to represent temporal variability at time scales below the long-term annual average (e.g. the native timescale of the (Revised) Universal Soil Loss Equation). Here, we test a low-complexity, spatially distributed model (WaTEM/SEDEM: W/S), to simulate 15-day erosion and sediment dynamics. A standardised modelling routine was applied to four monitored and well-studied catchments in North-West Europe with open-access discharge (Q) and suspended sediment load (SSL) data, creating a model workflow implementable with predominantly pan-European Union data.
