“…There are various, well-known ways of expressing mathematically the way in which water flows and its capacity to erode, transport and deposit sediments (Degani et al 1979;Mitasova et al 1996;Mitas & Mitasova 1998;Mitasova & Mitas 2001a,b;Warren et al 2005;Clevis et al 2006;Peeters et al 2006;Singh & Phadke 2006). We use a transport-limited algorithm to represent the flow of water over land surfaces, based on concepts described by Kirkby (1971) and adapted for two-dimensional surfaces by Moore & Burch (1986).…”

The evolution of Mediterranean landscapes during the Holocene has been increasingly governed by the complex interactions of water and human land use. Different land-use practices change the amount of water flowing across the surface and infiltrating the soil, and change water's ability to move surface sediments. Conversely, water amplifies the impacts of human land use and extends the ecological footprint of human activities far beyond the borders of towns and fields. Advances in computational modelling offer new tools to study the complex feedbacks between land use, land cover, topography and surface water. The Mediterranean Landscape Dynamics project (MedLand) is building a modelling laboratory where experiments can be carried out on the long-term impacts of agropastoral land use, and whose results can be tested against the archaeological record. These computational experiments are providing new insights into the socio-ecological consequences of human decisions at varying temporal and spatial scales.

“…This problem is known as equifinality or convergence of landforms and was discussed many times in geomorphographic papers 15 (e.g. Odoni, 2007, Peeters et al, 2006. It must be considered highly evident when modeling over longer geological time spans (several Ma), however for the time frame considered here (50 ka) it can be proposed as less important (Peeters et al, 2006).…”

It must be considered highly evident when modeling over longer geological time spans (several Ma), however for the time frame considered here (50 ka) it can be proposed as less important (Peeters et al, 2006). Therefore, we use the actual topography as predefined by the DEM as the initial topography for our modeling.…”

Abstract.We propose the implementation of a soil and landscape evolution model (SaLEM) for the spatiotemporal investigation of soil parent material evolution following a lithologically differentiated approach. Relevant parts of the established model GOLEM have been adapted for an operational GIS tool within the open source software framework 10 SAGA, thus taking advantage of SAGA's capabilities for geomorphometric analyses. The model is driven by paleo-climatic data (temperature, precipitation) representative for periglacial areas in Northern Germany over the last 50.000 years. The initial conditions have been determined for a test site by a digital terrain model and a geological model. Weathering, erosion and transport functions are calibrated using extrinsic (climatic) and intrinsic (lithologic) parameter data. First results indicate that our differentiated SaLEM approach shows some evidence for the spatiotemporal prediction of important soil parental 15 material properties particularly its depth. Future research will focus on the validation of the results against field data, and the influence of discrete events (mass movements, floods) on soil parent material formation has to be evaluated.

“…In addition, only few attempts were made to test the output of LEMs against observed spatial variation in soil erosion rates, because of the limited amount of data available on spatial erosion and deposition rates (Temme et al, 2011a). Peeters et al (2006) made the first attempt to reconstruct the initial landscape by simulating topographic development backwards in time over 5000 years, iteratively rejuvenating the topography by taking into account modeled erosion and deposition rates.…”

“…And the main dilemma is we do not know the initial topography condition. Peeters et al (2006) made a first attempt to reconstruct the initial landscape by simulating topographic development backwards in time over 5000 years, iteratively rejuvenating the topography by taking into account modeled erosion and deposition rates in a small catchment of 103 ha in the Belgian Loess Belt.…”
