Biala Lądecka (Biala Kłodzka) river is located in Lower Silesia (Poland) and its valley separates Góry Złote Mts. (Rychlebské hory Mts.) on the northeast from Góry Bialskie Mts. on the southwest. We investigated geomorphology research of the Biala Lądecka river basin, in order to determine if Quarternary tectonic activity at the Sudetic Marginal Fault is contributing to the river’s assymetry. Previous research provided in adajcent area by L. Finckh and G. Götzinger (1931), W. Walczak (1954) and A. Ivan (1966), Biala Lądecka river used to flow across the Góry Złote Mts. directly to Oderská nížina Lowland during Pliocene, currently it flows to Nysa Kłodzka Basin. Our research was focused on analysis of all available cartographic materials (geological and opographic maps), available literature and own detail geomorphological mapping of selected landforms. Spatial distribution of these landforms such as gullies, erosion trenches, dellens, alluvial plains, alluvial fans, springs, swamps, river terraces, could potentially indicate recent tectonic activity in the studied area. Moreover, stream network parameters (measured using DEM data) such as changes in erosion intensity indicated in longitudinal and cross-section profiles, slope gradient and morphometric indexes, e.g. Stream Length (SL) index (Hack 1973), for Biala Ladecka river basin were analyzed. In selected places geophysical measures were used was also performed to discover locations of sediments of the Biala Lądecka paleoriver.
