Geomorphology

BIOMAC participants: Harry Seijmonsbergen (PI), Kenneth Rijsdijk, Thijs De Boer and MSc students

Geomorphological research provides fundamental information on the spatio-temporal distribution of parent materials and the dynamics of surface processes. Geomorphological mapping techniques have been modernized by a variety of multi-temporal high-resolution data such as LiDAR-based elevation data, and (multi-spectral) satellite imagery and orthophotos derived from airborne, space born and UAV-flights. These methods provide in-depth understanding of current and past geomorphological processes and key environmental information at local to regional scales. Our current research is focused on:

  • Developing a multi-level and automated digital geomorphological mapping method

  • Quantification of geomorphological changes using object-based image analyses (OBIA) and supervised classification techniques

  • Quantification of natural and man-induced geomorphological landscape changes

Examples are the analysis of global mega-landslides, quantification of soil erosion in relation to land use and land cover changes, reconstruction of the deglaciation history in alpine and subalpine systems and the role of gypsum on landscape development.
