This study presents a Holocene sediment budget for the upland catchment of the Speyerbach in the Palatinate Forest, southwestern Germany. The influences of both, data availability and the choice of an appropriate soilscape model on the sediment budget calculations are investigated. For budget calculations the spatial distribution of soils was derived from the soil map 1:50,000. In order to model the sediment budget a reference soil thickness (a so-called soilscape model), which represents the initial conditions is necessary. As upland soils are developed in periglacial solifluction sheets, the main solifluction sheet (MSS, "Hauplage") showing a constant thickness and being affected by soil forming processes was chosen. Determining the initial thickness of the MSS is a crucial point. Therefore a statistical model using the local profile descriptions of the soil database for the Speyerbach catchment was set up. The error estimation for sediment budget based on the Speyerbach data is complicated. Future work will address the estimation of human impact by the analysis of historical data and datings of colluvial layers as well as a field validation of the computed sediment budgets
