Prediction of soil properties by digital terrain modelling
We investigated two approaches for large-scale analysis and prediction of the spatial distribution of soil properties in an agricultural landscape in the Canadian prairies. The first approach was based on the implementation of nine types of digital terrain models (DTMs) and regression analysis of soil and topographic data. The second approach used a concept of accumulation, transit, and dissipa...
متن کاملASSESSEMENT OF SOIL COLLAPSE PREDICTION METHODS
Expansive and collapsible soils are some of the most widely distributed and costly of geologic hazards. These soils are subject to changes in volume and settlement in response to wetting and drying, often resulting in severe damage to structures. Collapsing soils are generally characterized by sudden and large volume decrease at constant stress when inundated with water. A geotechnical engineer...

15 صفحه اولComparison of Four Spatial Interpolation Methods for Estimating Soil Moisture in a Complex Terrain Catchment
Many spatial interpolation methods perform well for gentle terrains when producing spatially continuous surfaces based on ground point data. However, few interpolation methods perform satisfactorily for complex terrains. Our objective in the present study was to analyze the suitability of several popular interpolation methods for complex terrains and propose an optimal method. A data set of 153...
متن کاملField Heterogeneity of Soil Organic Carbon and Relationships to Soil Properties and Terrain Attributes
Our objectives were to: (1) characterize SOC (0 to 1.53-m) within a 37-ha field typical of the Palouse region in eastern Washington; and (2) assess correlations and how much SOC variance could be accounted for by terrain and soil variables. A systematic, non-aligned grid of 177 georeferenced sample locations was established at the Washington State University Cook Agronomy Farm (CAF) near Pullma...
