Abstract Abstract Multi-process modelling of long-term landscape evolution using reduced-complexity models has become increasingly popular in the last decades. Landscape Evolution Model (LEM) LAPSUS is such a LEM that has recently been enhanced to incorporate 3D geology and to identify newly deposited sediments. The aim of this study was to model landscape evolution with LAPSUS in a catchment that experienced base level change due to lava-damming. After modelling several scenarios with lava dams of different erodibilities using a test Digital Elevation Model (DEM), the LEM was applied in an actual catchment which is part of the Upper Gediz basin near Kula, Turkey. Here, lava flows have blocked the trunk river and tributaries several times since the Early Pleistocene until the Holocene. Model inputs are a DEM, results of geomorphological and geological fieldwork and a climate reconstruction using regional climate data. Age control is derived from Ar-Ar dated lava flows and Post-IR IRSL (Post-Infrared Infrared Stimulated Luminescence) dated sediments. Modelling results are evaluated using river profile evolution, cross-sections, sediment yield and spatial redistribution of sediments. Results are expected to show the influence of lava damming and breaching on catchment evolution and answer the question whether catchment response to these past events is still on-going. This is of importance to find out whether the trunk river is in dynamic equilibrium with large-scale tectonic uplift of the area. The technique that we use has potential for answering these and related questions in other dam-affected fluvial systems.
