The present form of valleys is a result of complex land cover, geological and climatic conditions, which affect geomorphological processes of channel-floodplain (dis)continuum. The main aim of this paper is to present the characteristics of valley fill deposits in the Slavíč River basin with the use of fluvial geomorphological mapping, electrical resistivity tomography (ERT) and outcrop analysis. The ERT method was used to determine the structure of valley fill deposits. The lithofacial analysis was made to determine sets of fluvial formations. Two leading lithofacies were distinguished in the studied terrace outcrop: Gh facies, which were interpreted as fluvial forms influenced by deposits from debris flow material, and Gm facies, which were interpreted as fluvial forms with massive gravel transport.
