Quantifying catchment-scale soil property variation yields insights into critical zone evolution and function. The objective of this study was to quantify and predict the spatial distribution of soil properties within a high-elevation forested catchment in southern Arizona, USA, using a combined set of digital soil mapping (DSM) and sampling design techniques to quantify catchment-scale soil sp...

using low quality water on agricultural lands in south of tehran has increased the risk of soil salinity and created problems for some agricultural crops. this study was carried out to determine of soil salinity distribution and to produce salinity map. the mapping of salinity can also identify the saline and non-saline regions that are very effective for land management and choosing kind of cr...

There is a consensus about the necessity to achieve a quick soil spatial information with few human resources. Remote/proximal sensing and pedotransference are methods that can be integrated into this approach. On the other hand, there is still a lack of strategies indicating on how to put this in practice, especially in the tropics. Thus, the objective of this work was to suggest a strategy fo...

Planning for land use development, protection of good quality agricultural land, land degradation management and many other resource management issues requires reliable land resource information. Enhanced Resource Assessment (ERA) techniques were employed to rapidly assess and predict soil and landscape attributes throughout Cooloola Shire in South East Queensland. ERA uses landscape modelling ...

soil is one of the most important natural resources covering a large area of the land surface. soil plays a vital role in biosphere processes, such as energy balance, hydrology, biochemistry, and biological productivity. it supports plants that supply foods, fibers, drugs, and some other human needs. conversely, desert regions include about one third of earth lands and these regions have increa...

Abstract A significant deficiency of most computer models used for stream floodplain analysis is that the locations of structures impacted by floodwaters, such as bridges, roads, and buildings, cannot be effectively compared to the floodplain location. This research presents a straightforward approach for processing output of the HEC-RAS hydraulic model, to enable two- and three dimensional f...
