Choosing an Appropriate Hydrological Model for Rainfall-Runoff Extremes in Small Catchments
flood prediction infiltration Jizerské hory Mts
2015/7/28
Many of them are ungauged. The damage
in the catchments is enormous, and the length of the torrents is about 23% of the total length of small rivers in the
Czech Republic. The Smědá experimental m...
Modelling the impact of acid deposition on forest soils in North Bohemian Mountains with two dynamic models: the Very Simple Dynamic Model (VSD) and the Model of Acidification of Groundwater in Catchments (MAGIC)
air pollution Black Triangle historical deposition long-term modelling mass balance soil solution soil chemistry
2015/3/13
Enormous acid deposition that culminated in the 1970s contributed largely to accelerate the process of acidification of soils in northern Bohemia. As a consequence a wide forest decline occurred short...
A model experiment: competitive sorption of Cd, Cu, Pb and Zn by three different soils
desorption contamination heavy metals isotherm single- and multi-metal solutions
2015/3/10
The aim of this study was to evaluate and compare the competitive and individual sorption of Cd, Cu, Pb and Zn on three natural soils: a Gleyic Fluvisol (content of Cd 30, Cu 25, Pb 2297 and Zn 3718 m...
Storm-wise sediment yield prediction using hillslope erosion model in semi-arid abundant lands
abundant lands erosion model hillslope erosion model (HEM) Iran Khosbijan Research Centre
2015/3/9
Evaluation of soil erosion by existing models is needed as an important tool for managerial purposes in designation of proper water and soil conservation techniques. The present study aimed to assess ...
Effects of soil depth spatial variation on runoff simulation, using the Limburg Soil Erosion Model (LISEM), a case study in Faucon catchment, France
conditional simulation Faucon hydrograph kriging LISEM soil depth
2015/3/5
Soil depth is an important parameter for models of surface runoff. Commonly used models require not only accurate estimates of the parameter but also its realistic spatial distribution. The objective ...
Field study of chlorotoluron transport and its prediction by the BPS mathematical model
chlorotoluron contaminant transport field study half-life degradation herbicides mathematical model BPS
2015/3/2
The chlorotoluron transport in the soil profiles was studied under field conditions on three different soil types of the Czech Republic. The herbicide was applied on 21. 4. 2005 on a four-square meter...
Application of RothC model to predict soil organic carbon stock on agricultural soils of Slovakia
agricultural land RothC Slovakia soil organic carbon
2015/3/2
Soil organic matter (SOM) takes part in many environmental functions and, depending on the conditions, it can be a source or a sink of the greenhouse gases. Presently, the changes in soil organic carb...
The impact of artificial drainage on water quality in two model areas in the bohemian forest foothills
