Geomorphic response of streams to neotectonic deformation in low relief areas: case study of Bilogora Mt. (NE Croatia)

Understanding about tectonic and surface processes which control topography and development of landscape features represents the core for many quantitative morphotectonic investigations using nowadays widely available digital elevation models (DEMs). This work was aimed to identify areas with neotectonic deformation signature in Bilogora Mt. area by means of DEM based morphometric analysis combined with geological, geophysical and seismotectonic data(Prelogović & Velić, 1988 & Herak et al., 2009).In order to analyze a potential geomorphic response of streams to ongoing tectonic activity we employed a DEM raster with cell resolution of 10 m modeled according to procedure described in Matoš et al. (2012). Study area was truncated into 130 drainage units, each unit was analyzed by computing its morphometric parameters that include: hypsometric integral-Hi, absolute asymmetry factor-AF(abs) and statistical parameters of longitudinal stream profiles, i.e. maximal concavity-Cmax, distance from the source-Δl/L and concavity factor-Cf. See attached extended abstract.
