Permanent exploitation of agricultural machinery and equipment supposes excessive compression of soil cover by undercarriage, especially by wheels, which leads to crop yield decline, high energy consumption and decrease of productivity. The main goal of the research presented in the article appears determination of the dependencies between soil reluctance and compaction, reflecting peculiarities of the curve of depression of the deformation agent in soil. The research analyzes development of the core of compression during compression of stamping tool.

The environment is deteriorating on a long-term basis in the Ejina River Basin in Inner Mongolia, China as a result of a water shortage. The shortage was caused by increased water use by industries and agriculture after 1992 along the upper part of the Ejina River. In 2002, the Chinese National Water Resource Agency instituted a water sharing plan which resulted in more water being released downstream to a region including the Kyoen Delta. The repartition will have an effect on vegetation increase in the Kyoen Delta area.

The spatial distribution of vegetation trends identified by time series analysis of the normalized difference vegetation index (NDVI) for the Mongolian grasslands was cross-referenced with the recently obtained land use/cover data and socioeconomic information in the geographic domain. Global Inventory Modeling and Mapping Studies (GIMMS) dataset with an 8-km resolution provided by the Global Land Cover Facility (GLCF) of the United States were used to compute the vegetation trends.

Accessibility to cloud-free optical sensor images is essential for large-area monitoring of land and forest cover changes. In this study, the acquisition probabilities of cloud-free images were analyzed using MODIS cloud mask products from 2000 to 2008 in Southeast Asia. The daily cloud masks were summarized into monthly acquisition probabilities for cloud-free images over the period at a spatial resolution of 1km. The mean annual acquisition probability profiles were extracted averaging nine years' observation.

The paper demonstrates the application of a new water accounting plus (WA+) framework to produce information on depletion of water resources, storage change, and land and water productivity in the Indus basin. It shows how satellite-derived estimates of land use, rainfall, evaporation (E), transpiration (T ), interception (I ) and biomass production can be used in addition to measured basin outflow, for water accounting with WA+. It is demonstrated how the accounting results can be interpreted to identify existing issues and examine solutions for the future.

Vegetation mapping provides basic information for forest management and planning. In remote sensing research, the process of creating an accurate vegetation map is an important subject. Recently, there has been growing research interest in the object-oriented image classification techniques. The object-oriented image classification consists of multi-dimensional features including object features and thus requires multi-dimensional image classification approaches.

By increased rural-urban migration in many African countries, the assessment of changes in catchment hydrologic responses due to urbanization is critical for water resource planning and management. This paper assesses hydrological impacts of urbanization on two medium-sized Zimbabwean catchments (Mukuvisi and Marimba) for which changes in land cover by urbanization were determined through Landsat Thematic Mapper (TM) images for the years 1986, 1994 and 2008. Impact assessments were done through hydrological modeling by a topographically driven rainfall-runoff model (TOPMODEL).

limatic and hydrological changes will likely be intensified in the Upper Blue Nile (UBN) basin by the effects of global warming. The extent of such effects for representative concentration pathways (RCP) climate scenarios is unknown. We evaluated projected changes in rainfall and evapotranspiration and related impacts on water availability in the UBN under the RCP4.5 scenario. We used dynamically downscaled outputs from six global circulation models (GCMs) with unprecedented spatial resolution for the UBN.

Post-technogenic ecosystems represent informative natural models of initial pedogenesis and restoration under the abandoned and reclamation practices. The purpose of this study conducted in one of the largest limestone quarries of Leningrad region was to examine successions of plant and microbial communities. Species composition and vegetation cover were estimated for different plant communities within each ecotype of quarry.

The study area Rangapur watershed covers an area of about 2079 ha, is one of the drought prone areas in the middle Krishna Basin in Raichur district of Karnataka. An attempt is made to suggest location priority plan for the sustainable development of the area using GIS and remote sensing techniques. The IRS P6 LISS III imagery was used for the preparation of land use/land cover and hydrogeomorphology maps. Geologically most of the watershed is covered by the rocks of Archean age i.e. granite gneiss.
