Neotectonic control on river sinuosity at the western margin of the Little Hungarian Plain

Classic sinuosity values from the reconstructed river courses have been derived using several window sizes. The calculated values show surprisingly strong local variations, considering the low-relief and lithological homogeneity of the area. The spatial distribution of the pronounced sinuosity variations coincides with the location of Late Miocene faults well-known from seismic data. On-going active tectonic activity along these faults is further indicated by the local earthquake record and geomorphic parameters derived from high-resolution digital elevation models. In conclusion, river sinuosity calculations represent a sensitive tool for recognizing neotectonic activity in low-relief areas.
