Evaluation of discrepancies in spatial distribution of rainfall erosivity in the Czech Republic caused by different approaches using GIS and geostatistical tools
covariate geostatistics R factor rainfall intensity rainfall total USLE/RUSLE-GIS method
2017/6/26
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...
Evaluation of field performance of BEST aeolian sediment catcher in sandy-loam soil of arid zone of Turkey
sediment trap trap efficiency wind erosion
2017/6/26
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...
Evaluation of Different Soil Water Potential by Field Capacity Threshold in Combination with a Triggered Irrigation Module
field water capacity dual-porosity model HYDRUS-1D
2015/7/30
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...
Evaluation of techniques for ploughshare lifetime increase
ploughshare soil overlaid materials agricultural machines wear
2015/7/2
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...
The evaluation of degraded land by application of the contingent method
contingent valuation method (CVM) land evaluation land protection land reclamation public awareness of soil protection willingness to pay
2015/3/10
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...
Field performance evaluation of micro irrigation systems in Iran

2015/3/10
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 ...
Evaluation of the variability in runoff and sediment loss in successional fallow vegetation of Southern Nigeria
erosional losses soil erosion rainfall vegetation components vegetation fallows
2015/3/10
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...
Evaluation of the relationships between runoff-rainfall-sediment related nutrient loss (A case study: Kojour Watershed, Iran)
clockwise hysteretic loop organic matter phosphorus loss regression models suspended sediment
2015/3/9
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...
Evaluation of ground penetrating radar and vertical electrical sounding methods to determine soil horizons and bedrock at the locality Dehtare
geophysical method parent rock soil layer soil survey
2015/3/9
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"...
Field evaluation of various mathematical models for furrow and border irrigation systems
