Abstract

Geological mapping, geophysical surveys, test pits, and shallow borings were used to identify and evaluate a site containing a landslide complex. An investigation was performed to characterize the extent and nature of the complex, determine the susceptibility to movement, and the potential for impact on a nearby proposed reservoir and dam. The methods of investigation established a relationship between the morphology, geology, and hydrology of the slide complex. The surface of the slide was initially identified by a series of scarps, seeps, and slopes. Seismic refraction and resistivity surveys were performed to determine depths to the basal failure surface and to aid in the selection of two borehole locations. The results of the combined investigation activities led to estimation of an areal extent of about 35 ha, a thickness of about 12.5 m. in the drilled area, and a low potential for rapid displacement.
