FIELD INVESTIGATION

The field investigation is the decisive part of a study of landslides and landslide-prone areas. The investigation serves two purposes: to identify areas subject to sliding when future construction is being planned; to define features of and environmental factors involved in an existing slide. Field investigations cover topography, geology, water, physical properties and ecological properties. In planning for investigations consideration must be given to the area of investigation, time span, and the stages of the investigation. The topography is first determined by aerial surveys but detailed ground surveys must also be included. Comments are made on the representation of topographic data. Subsurface exploration is discussed with particular reference to geologic reconnaissance, test pits and trenches, and geophysical studies. Geologic maps, profiles, cross sections, and three dimensional diagrams and models which aid in depicting forms that will aid in correcting the conditions are discussed. Surface water and groundwater aspects are discussed, as well as environmental factors and field testing. Correlation and the three-dimensional study of acquired data is described.
