Landforms in the Permian volcanites on the Strážník hill and the adjoining Jizera river valley

Paper deals with landforms on Permian volcanic rocks (dolerites River near thevillage Háje nad Jizerou. Studied landforms are result of gravitational slope movements, of Pleistocene (and Holocene) frost weathering and erosion

Small sandstone landforms

The article deals with small landforms developed on sandstones. These landforms are characterized from genetic viewpoint (there are described geomorphologic processes which formed these landforms). The article corrects the ...

Changes in the channels and floodplain of Sudetic rivers in the Morava River Basin after flood in July 1997

The flood of July 1997 was the most severe natural disaster in the basin of the Morava River in the Czech Republic. In the paper attention was devoted to geomophic changes in channels and floodplain of rivers found after theflood. In the paper a rang...

Sandstone landforms shaped by negative feedback between stress and erosion

Weathering and erosion of sandstone produces unique landforms(1,2 assumed to not play a role in landform preservation(3) and to instead increase weathering rates(4,5). Here we show that increased stress within a landfor...

Fast evolving conduits in clay-bonded sandstone: Characterization, erosion processes

In Strelec Quarry, the Czech Republic, an underground conduit network a catchment of 7 km2 developed over 5 years by groundwater flow in Cretaceous marine quartz sandstone. Similar landforms at natural exposures are stabilized by case harden...

Landform transformation and long-term sediment budget for a Chernozem- dominated lowland agricultural catchment

on interpreting records of erosion and deposition from 185 soil cores and six valley cross settlement history. For the first time, we document changes to human-induced landforms depressions within the original valley botto...

Origin of ?rock cities, pillars and cleft-conduits in kaolinite-bonded sandstone: New insight from study in sandstone quarry where landforms recently evolve

Based on measurements of relative erodibility, ambient and water-saturated tensile strength at natural and quarry exposures three distinct kinds of surfaces were distinguished (erodible sandstone, sub-vertical fracture surfaces and case hardened surf...

Fast evolving conduits in clay-bonded sandstone: Characterization, erosion processes and significance for the origin of sandstone landforms

landforms at natural exposures (conduits, slot canyons, undercuts) are stabilized stage to maturity,and to characterize the erosion processes which may form natural landforms prior to stabilization. A new technique was dev...
