WebJan 7, 2024 · We studied infiltration and fractal mechanisms on sloping farmlands in a small watershed in Shandong Province in the rocky mountain areas of northern China. We studied soil fraction and soil water retention curves, and developed a soil infiltration model to analyze its quantitative relationship with soil particle size and pore dimensions under … WebWe relate the water retention curves directly to the fractal dimension of the Sierpinski carpet and show that the fractal dimension strongly controls the water retention properties of the Sierpinski carpet "soil". Higher fractal dimensions are shown to mimic clay-type soils, with very slow dewatering characteristics and relatively low fractal ...

WebFeb 1, 1998 · A conceptual model based on the assumption that soil structure evolves from a uniform random fragmentation process is proposed to define the water retention function. The fragmentation process determines the particle size distribution of the soil. WebApr 12, 2024 · Soil depths had an obvious effect on soil macropore features during the NWD cycles. The decrease in soil macropore number, macroporosity, fractal dimension and connectivity density were observed after the cycles of NWD, and was adverse to soil water retention, soil quality and crop production. diamond b transport
