Abstract
Abstract. We propose the implementation of the 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 Geomorphic/Orogenic
Landscape Evolution Model (GOLEM) have been adapted for an
operational Geographical Information System (GIS) tool within the open-source software framework System for Automated Geoscientific Analyses (SAGA), thus
taking advantage of SAGA's capabilities for geomorphometric analyses. The
model is driven by palaeoclimatic data (temperature, precipitation)
representative of 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 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.
