The study presents all approaches of rainfall erosivity factor (R) computation and estimation used in the Czech Republic (CR). A lot of distortions stem from the difference in erosive rainfall criteri...
Field measurement of wind erosion is still a great challenge for researchers. In this study, field performance of a newly designed sediment trap BEST (Basaran and Erpul Sediment Trap) was evaluated fo...
Irrigation efficiency improvement requires optimization of its parameters like irrigation scheduling, threshold and amount of water usage. If these parameters are not satisfactorily optimized, negat...
The aim of the research is to increase the lifetime of a mould board by means of a constructional setting of an overlaid material. The lifetime increasing of the ploughshare by means of the overla...
Industrial activities in the Czech Republic have brought into existence many degraded and contaminated sites. Such areas are not suitable for farming, building or recreation purposes. The necessary re...
The efforts to introduce the micro irrigation system in Iran go back as far as the year 1990. The area under micro irrigation system in Iran covers about 400 000 ha and it is estimated to double (800 ...
The effects of three different ages of natural fallow vegetation on runoff and sediment loss were investigated in a part of the rainforest zone of Nigeria. Measurements of runoff amount and sediment l...
Suspended sediment (SS) resulted from distributed soil erosions facilitates soil organic matter and phosphorus (P) transportation and influences soil depletion and water quality. Organic matter (OM) i...
Recently, geophysical methods have been widely used in many fields including pedology. Two of them, ground penetrating radar (GPR) and vertical electrical sounding (VES) were employed at the Dehtá"...
In this study, three mathematical models in the SIRMOD package including the hydrodynamic (HD), zero inertia (ZI), and kinematic wave (KW) models were tested using the data from several field experime...
In this paper is presented the comparison of the selected hydrometeorological data from two experimental micro-scale catchments Modrava 1 (0.1 km2 ) and Modrava 2 (0.17 km2 ) in upper parts of Bohem...
: The dissipation of solar energy and consequently the formation of the hydrological cycle are largely dependent on the structural and optical characteristics of the land surface. In our study, we sel...
Measurements of the runoff intensity (i.e. its volume and amounts of washed out soil particles) were performed on experimental plots with the slope gradient of 5° within the period of 2004–2008. Exper...
Soil temperatures were analysed for the climatological station Pohořelice during the period of 1961–2000. According to the agroclimatic zoning, this region is a part of warm macroarea, mainly war...
In the present study and research work, land suitability evaluation (qualitative classification) was made for the Bilverdy research station of the Islamic Azad University in East Azarbaijan for wheat,...
