Stress Ecology in Mining Landscape: Postindustrial Deposits in Comparison with their Surroundings as the Environments for Selection of Plants with Small and Large Genome Size Open
This pilot case study compares genome sizes of two groups of species (conspecific plants) which spontaneously colonize interior space within abandoned industrial area and/or deposits, and those ones occurred in adjacent vicinity. Testing o…

Arable Land Abandonment in the Czech Villages of Romanian Banat Area and Plant Diversity in Old-Fields Open
The aim of this study is to differentiate old-field plant communities along the abandonment time and/or environmental gradient in the landscape surrounded villages with established Czech settlers in Romanian Banat area conserving tradition…

Invasion of Schrader’s Bromegrass (<i>Bromus catharticus</i>) and Expansion of the Cairo Suburban Land: are they in Coincidence? Open
Set of phytocoenological records obtained in nineties of the twentieth century from extensively farmed patches and/or grasslands dominated by invasive grass Bromus catharticus in suburban area of Cairo, Egypt, is related to running and per…

The use of Snyder synthetic hydrograph for simulation of overland flow in small ungauged and gauged catchments Open
The paper presents the results of simulated overland flow on the Třebsín experimental area, Czech Republic, using the Snyder synthetic unit hydrograph. In this research an attempt was made to discover a new approach to overland flow simula…

Implementation of the curve number method and the KINFIL model in the Smeda Catchment to mitigate overland flow with the use of terraces Open
The Smeda catchment, where the Smeda Brook drains an area of about 26 km2, is located in northern Bohemia in the Jizerské hory Mts. This experimental mountain catchment with the Bily Potok downstream gauge profile was selected as a model a…

Trees as Ecosystem Engineers Driving Vegetational Restoration/Retrogradation of Industrial Deposits in Cultural Landscape Open
Industrial processes are marked with various deposits of wastes in landscapes. They are typically characterized by high pollution levels in all their ecosystem components, including soil, water and air. Even more than natural ecosystems, a…

Comparison of water regimes of two dump catchments in the Krušné hory Mts. (Czech Republic) in dry years using a hydrological balance Open
The dump catchments water regime optimization is one of fundamental recultivation operations in areas devastated after surface coal mining. Two dump catchments (at Radovesice and Loket in the Krušné hory Mts., Czech Republic) were selected…

Use of terraces to reduce overland flow and soil erosion, comparison of the HEC-HMS model and the KINFIL model application Open
In our study, a system of seven natural terraces interspersed with six field belts situated at the Knínice locality (the Ore Mts., North-West Bohemia) was selected as the experimental catchment area. Overland flow was computed using two di…

Impact of overland flow on soil characteristics in Třebsín experimental plots Open
This paper describes the continuation of simulated outcomes from the plots No. 4 and No. 5 with two different soils, using the KINFIL model to assess the runoff from extreme rainfall. The KINFIL model is a physically-based, parameter-distr…
View article: The influence of woven geotextiles on ponding time and overland flow
The influence of woven geotextiles on ponding time and overland flow Open
Nowadays, both synthetic and natural geotextiles are used to mitigate water erosion processes on hillslopes. Jute and coir are most suitable materials for the production of woven geotextiles. They are used for a variety of purposes - from …
View article: Use of terraces to mitigate the impacts of overland flow and erosion on a catchment
Use of terraces to mitigate the impacts of overland flow and erosion on a catchment Open
The paper presents the impact of a historical system of terraces constructed centuries ago to mitigate the effect of a steep slope on overland flow. Systems of this type were constructed in past centuries by land owners, who then ploughed …

Computing Hydrological Balance in the Medard Mining Pit With the Help of the Water Balance Conceptual Model (WBCM) Open
A positive water balance is the main prerequisite for successful hydro-reclamation of residual mining pits. Under the current conditions of climate change, long dry periods occur more frequently, which may have a negative impact on the…

Impact of evapotranspiration on diurnal discharge fluctuation determined by the Fourier series model in dry periods Open
Precise measurements of discharges at the outlet of a small catchment, using high resolution sensing equipment, can currently be done without difficulty. In particular, measurements can take place even during dry periods, when high tempera…
