Development of semi-physically based model to predict erosion rate of kaolinite clay under different moisture content

Abstract: Understanding the susceptibility of soils to concentrated flow erosion is imperative for predicting sustainability of various engineering structures and assessing environmental integrity. Currently, a widely used model is empirical in nature. In this study, we developed a semi-physically based model that predicts the rate of concentrated flow erosion of kaolinite clay based on tensile and erodibility characteristics. To develop this model, direct tensile tests and jet erosion tests (JETs) were performed on kao… Show more

“…This result supports the opinion that the generated pore water pressure from a high hydraulic gradient would be dissipated attributed to the enlargement of the soil pipe (Hicher 2013;Ouyang and Takahashi 2016). Hydraulic non-equilibrium within soil pipes would be exhausted by soil erosion and the hydraulic potential energy would be diminished during the process of sediment detachment and transport (Wilson et al 2009;Sang et al 2015;Nguyen and Indraratna 2020).…”

“…Bonelli and Brivois (2008) found that the radial erosion propagation under the given pressure drop obeyed a scale exponential law. Sang et al (2015) developed semi-physically models for predicting the enlargement of the hole in the HET. The mechanism of progressive internal erosion leading to instability of the structure was interpreted and modelled by Onate et al (2011) andHicher (2013).…”

“…Several researchers (Hanson, 2001;Wynn and Mostaghimi, 2006;Hanson and Hunt, 2007;Wynn et al, 2008;Regazzoni et al, 2008;Sang et al, 2015) have studied the influence of soil properties on soil erodibility, such as soil texture, soil moisture, bulk density, soil compaction, soil chemical, and vegetation. No studies or researches till now studied the influence of Lead pollution on the soil erodibility.…”
