Bayesian Approach for Predicting Soil-Water Characteristic Curve from Particle-Size Distribution Data

Energies, 2019
Soil-water characteristic curve (SWCC) is a significant prerequisite for slope stability analysis involving unsaturated soils. However, it is difficult to measure an entire SWCC over a wide suction range using in-situ or laboratory tests.

A survey about characteristics of soil water retention curve

IOP Conference Series: Earth and Environmental Science, 2018
The characteristic of soil water retention curve is a hot issue in soil water search. There is multifarious variation of soil water matrix potential if soil water content change. The relation curve is of great importance. In this paper, based on fractal theory, we analyze and discuss several aspects including mathematics models, application and ...
