Soil-forming materials and soil texture as shown on small-scale soil maps

AbstractEarth system models use soil information to parameterize hard-to-measure soil hydraulic properties based on pedotransfer functions. However, current parameterizations rely on sample-scale information which often does not account for biologically-promoted soil structure and heterogeneities in natural landscapes, which may significantly alter infiltration-runoff and other exchange processes at larger scales. Here we propose a systematic framework to incorporate soil structure corrections into pedotransfer functions, informed by remote-sensing vegetation metrics and local soil texture, and use numerical simulations to investigate their effects on spatially distributed and areal averaged infiltration-runoff partitioning. We demonstrate that small scale soil structure features prominently alter the hydrologic response emerging at larger scales and that upscaled parameterizations must consider spatial correlations between vegetation and soil texture. The proposed framework allows the incorporation of hydrological effects of soil structure with appropriate scale considerations into contemporary pedotransfer functions used for land surface parameterization.

Small Scale Soil

This paper presents the blast loading of small scale soil barrier subjected to surface burst,analysed by using AUTODYN 2D and AUTODYN 3D.Results from the AUTODYN analyses are then compared with published experimental results. Good agreements with published experimental results are obtained for numerical analysis by using AUTODYN 3D for peak pressure at the front part of the barrier. In this case study, AUTODYN 2D numerical analyses provide higher pressure readingsat about 62% and 36% differences as compared with the published experimental results for pressure measurement at the middle front and back of soil barrier surface. The discrepancy of AUTODYN2D results was due to geometric dissimilarity from the actual experimental test. For complex geometries shape of barrier, that involves different shapes and configurations, three dimensional analyses are required to accurately predict the complex reflections and interactions associated with the propagation of the blast wave.
