A preliminary result of lamtakong embankment dam safety assessment using integrated subsurface electrical resistivity and shear wave velocity model

Abstract

© EAGE 2020. Clustering model using integrated subsurface electrical resistivity and shear wave velocity model provides conspicuously subsurface structure of the Lamtakong embankment dam as show in Fig 1. Furthermore, the Anomaly is found in manual method located around elevation at 250 meters, and distance at 250 meters. The resistivity and velocity of the anomaly are low, so that can be interpreted as a possible leakage and internal erosion zone of the Lamtakong embankment dam. The anomaly is located at the foundation of the dam. Incidentally, the automatic method developed by fuzzy c-means clustering algorithm and selected center method is incomplete. In future study, considering other factors may develop the data grouping of automatic method such as engineer factor.
