Digital terrain models (DTM) with high resolution are ideally suited for a systematic mapping of geomorphological structures, such as fluvial terraces, with high accuracy. We developed a semi-automatic GIS method to correlate individual terrace treads stratigraphically using a 1 m DTM. It is applied to a gorge of River Wurm (Southern Bavaria, Germany). The approach yields suitable and plausible results and the presented map provides a clear and easy overview of correlated terrace levels. The investigation enhances the understanding of the spatial and temporal evolution of the va ll ey and demonstrates the great benefit of high-resolution DTMs and the digital processing of geodata for the geomorphological research.
