Geophysical Evaluation of the Inner Structure of a Historical Earth-Filled Dam

open access: yesProceedings, 2018
Small earth dams usually lack the detailed seepage monitoring system that would provide high resolution data on changes in seepage flow. Alternative solution is monitoring of the temperature and electrical resistivity in the body of the dams. Geophysical
