Hydraulic Conductivity and Aggregation of Fine-Textured Soil Under Intensive Cattle Grazing

Unsaturated Hydraulic Conductivity of Fractal-Textured Soils

Estimating Hydraulic Properties of a Fine-textured Soil Using a Disc Infiltrometer

Inverse optimization of parameters offers an economical means to infer soil hydraulic properties from in situ measurements of infiltration. We evaluated optimization strategies to inversely estimate soil hydraulic parameters using field measured tension disc infiltrometer data. We estimated the parameters n, , and Ks of the van Genuchten-Mualem (VGM) model, and a piecewise representation of con...

Effects of sewage sludge and its biochar on soybean yield in fine-textured loess soil

Background: The application of biochar as a soil amendment has achieved popularity and has been found to improve considerably soil nutrient status and plant productivity in low fertile soils. Methods: This study used two different methods to apply sewage sludge and sewage sludge biochar with three replicates in a completely randomized block design. The experiment included (1) control, (2) mulc...

Computer Erosion Modeling Considering Soil Hydraulic Conductivity

Improved computer models of erosion have been developed, considering soil hydraulic conductivity. The models deal with erosion of levees, dams and embankments due to overtopping. The simulations trace the formation of rills and gullies, beginning with initial overtopping and continuing to final breaching. Physical models performed at 1-g and high g using a geotechnical centrifuge have been used...
