Joint inversion of self-potential and active-source electrical data constrained by a Gaussian mixture model prior for detecting water-bearing anomalies in tunnels

Water-bearing fractured zones, dissolution fractures and infilled low resistivity bodies ahead of tunnel faces generally produce low resistivity anomalies and self-potential (SP) volumetric source strength responses. However, the restricted observation space in tunnels and the li...
