The mean annual, winter half-year and summer half-year fows at 86 water level gauges in the Upper Vistula Basin in the years 1951–2015 were examined. The Ward’s hierarchical cluster analysis was used for grouping sub-catchments in reference to the standardized aforementioned fows. Trends analysis was performed for each cluster of catchments in all combinations of periods not shorter than 20 years...
Various morphologies of cliffs built of different quartzose rocks in the Świętokrzyskie (Holy Cross) Mts. (upland region, central Poland) – from Cambrian quartzites and Devonian quartzitic sandstones to Triassic and Jurassic porous sandstones – were described in order to examine the constraints of their lithological and spatial occurrence. The quantitative study of the occurrence of these morphologies...
One of the key topics in modern geomorphology is the identification of locations where the drainage network begins. However, there still exists a gap in the research literature in the area of channel head location in flysch regions characterized by unique hydrogeological conditions. In this study, we have identified the spatial distribution of channel heads and determined threshold values of morphometric...
