Predicting the impact of land cover and climate change on hydrologic responses using modeling tools are essential in understanding the movement and pattern of hydrologic processes within the watershed. The paper provided potential implications of land conversions and climate change scenarios on the hydrologic processes of Muleta watershed using soil and water assessment tool model. Model inputs...

Examples from the Murray–Darling basin in Australia are used to illustrate different methods of disaggregation of reconnaissance-scale maps. One approach for disaggregation revolves around the de-convolution of the soil–landscape paradigm elaborated during a soil survey. The descriptions of soil map units and block diagrams in a soil survey report detail soil–landscape relationships or soil top...

The increasing use and capability of geocomputation tools, as well as increasing availability of land resource information, offer opportunities to utilise such tools for the effective management of information for planning purposes. One among those is the development of spatially-based models that may be used for efficiently undertaking land suitability assessment based on available information...

Basically, water erosion is one of the most significant environmental problems in the world. The major variables affecting soil erosion are climate, soil, vegetation, and topography. Of these, vegetation and, to some extent, soil and topography may be controlled. However, for adequate intervention, reliable and representative model parameters and running conditions are necessary, which requires...

We review various recent approaches to making digital soil maps based on geographic information systems (GIS) data layers, note some commonalities and propose a generic framework for the future. We discuss the various methods that have been, or could be, used for fitting quantitative relationships between soil properties or classes and their ‘environment’. These include generalised linear model...

The polygon boundaries on the digital map of land surface characteristic are conventionally represented as a sharp change (categorical format), which results in discrepancy between real world phenomena and the information presented by boundaries on map, and it is especially true for soil properties. This paper presents a probable impact 5 of the representation of geographic boundary for the soi...

development of sensors to detect the location and depth of hard pans in real time is a major restriction on the application of site specific crop management (sscm). in this study, a soil compaction profile sensor equipped with four horizontal operating penetro-meters for on-the-go sensing and mapping of the location and intensity of hard pans arti-ficially formed in a soil bin was developed and...
