Coupled inversion of hydraulic and self‐potential data from transient outflow experiments to estimate soil petrophysical properties

Abstract: Hydraulicproperties of soils could play an important role in affecting the partitioning of precipitation in the critical zone. In addition to traditional approaches, in the last two decades, many geophysical methods have been used to aid the hydrologic characterization and measurement of geological materials. In particular, the self-potential (SP) method shows great potential in these hydrogeophysical applications. The objective of this study is to evaluate whether the addition of SP data can improve the estim… Show more

“…The transient responses of the sand during drainage ( Q , h p , and Δ V ) are used to estimate the saturated/unsaturated properties of the sample using the coupled, stochastic hydrogeophysical inversion code developed in Xie et al. (2021). The inversion uses Markov Chain Monte Carlo (MCMC) technique to generate samples that follow the posterior distributions of the model parameters (Vrugt et al., 2003).…”
