A University of Wyoming researcher and his team have discovered that weathering of subsurface rock in the southern Sierra Nevada Mountains of California is due more to rocks expanding than to chemical...
Using model reduction to predict the soil-surface C18OO flux: an example of representing complex biogeochemical dynamics in a computationally efficient manner
Using model reduction predict the soil-surface C18OO flux representing complex biogeochemical dynamics computationally efficient manner

Earth system models (ESMs) must calculate large-scale interactions between the land and atmosphere while accurately characterizing fine-scale spatial heterogeneity in water, carbon, and other nutrient...
An inversion method based on multi-angular approaches for estimating bare soil surface parameters from RADARSAT-1
multi-angular approaches estimating bare soil surface parameters
2010/12/22
This paper focuses on inversion of these parameters using a multi-angular approach based on RADARSAT-1 data with incidence angles of 35° and 47° (in mode S3 and S7). This inversion was performed with ...
Describing soil surface microrelief by crossover length and fractal dimension
soil surface microrelief rossover length fractal dimension
2009/11/3
Accurate description of soil surface topography is essential because different tillage tools produce different soil surface roughness conditions, which in turn affects many processes across the soil s...
Quantification of tillage,plant cover,and cumulative rainfall effects on soil surface microrelief by statistical,geostatistical and fractal indices
tillage plant cover cumulative rainfall effects soil surface microrelief
2009/11/2
Changes in soil surface microrelief with cumulative rainfall under different tillage systems and crop cover conditions were investigated in southern Brazil. Surface cover was none (fallow) or the crop...
Assessing soil surface roughness decay during simulated rainfall by multifractal analysis
soil surface roughness decay simulated rainfall multifractal analysis
2009/11/2
Understanding and describing the spatial characteristics of soil surface microrelief are required for modelling overland flow and erosion. We employed the multifractal approach to characterize topogra...
