Summary
Robust understanding of the fine-grained sediment cascades of temperate agricultural catchments is essential for supporting targeted management for addressing the widely reported sediment problem. Within the UK, many independent field-based measurements of soil erosion, sediment sources and catchment suspended sediment yields have been published. However, attempts to review and assess the compatibility of these measurements are limited. The data available suggest that landscape scale net soil erosion rates (∼38 t km<sup>-2</sup> yr<sup>-1</sup> for arable and ∼26 t km<sup>-2</sup> yr<sup>-1</sup> grassland) are comparable to the typical suspended sediment yield of a UK catchment (∼44 t km<sup>2</sup> yr<sup>-1</sup>). This finding cannot, however, be reconciled easily with current prevaili
