Water migration changes the water distribution of loess and significantly affects engineering properties loess. However, because characteristics such as sensitivity special structure, it is still difficult to understand trend The objectives this study are investigate diffusion coefficient soil-water characteristic curve (SWCC) loess, focusing on effect temperature density, establish a mixed equ...

Fine sediments in debris-flow gullies are quaternary with a particle size of less than 2 mm. Since they easy to suspend flowing water, their stability plays key “probe” role early warning. The permeability coefficient is the main internal control factor fine sediment debris flow. However, there no quantitative model between and its influencing factors, which seriously affects evaluation flow se...
