LANDSLIDES: INVESTIGATION AND MITIGATION. CHAPTER 9 - SURFACE OBSERVATION AND GEOLOGIC MAPPING
This chapter begins with a discussion of the duties of the geologist on an existing project that has developed an unstable slope or on a proposed project that has the potential for slope movement. This is followed by a discussion of the work required before field visitation. This involves planning the surface observation and geologic mapping and includes identifying the area of interest and collecting and reviewing geologic and geotechnical information, aerial photographs, and topographic maps. Subsequent sections of this chapter deal with (1) on-site engineering-geologic investigations by reconnaissance observations, engineering-geologic mapping, and reconnaissance instrumentation; (2) detailed ground surveys of landslide sites using the basic survey methods as well as recent advances in survey techniques; (3) data interpretation and presentation; (4) guidance for subsurface investigations; (5) correlation of surface and subsurface data; (6) the need for additional field information; and (7) the cost of surface investigations.
