FIELD AND LABORATORY INVESTIGATIONS

THE SCOPE OF INVESTIGATION OF A LANDSLIDE AREA OR A PO- TENTIAL LANDSLIDE AREA WILL DEPEND ON THE IMPORTANCE OF THE SLIDE. THERE ARE SEVERAL FACTORS THAT SHOULD BE ASCERTAINED IN THE INVESTIGATION OF ANY SLIDE IN ORDER TO ASSESS ITS IMPORTANCE. THESE INCLUDE: (1) LOCATION, (2) EFFECT ON TRAFFIC, (3) SIZE, (4) MATERIAL, (5) WATER, (6) WEATHER, (7) EVIDENCE OF MOVEMENT, AND (8) HISTORY OF SLOPE. THE PUR- POSE OF A LANDSLIDE INVESTIGATION MAY BE TO DETERMINE THE CAUSE OF THE SLIDE, PLAN APPROPRIATE MEASURES FOR REPAIR AND RECONSTRUCTION, OR TO PROVIDE THE NECESSARY DATA FOR PROSE- CUTION OR DEFENSE OF A DAMAGE SUIT, FOR A THEORECTICAL IN- VESTIGATION. EACH INVESTIGATIVE FACTOR IS DISCUSSED WITH METHODS OF INVESTIGATION. THE FIELD DATA COMPRISED THE OB- SERVABLE AND MEASURABLE FACTS IN AND ADJACENT TO THE SITE. THE PHOTOGRAPHIC RECORD OF THE SLIDE IS MOST IMPORTANT IN PROPERLY DOCUMENTING THE SUCCESSIVE STAGES IN DEVELOPMENT OF THE SLIDE. THE MINIMUM SUMMATION OF THE DATA SHOULD INCLUDE A BASE MAP SHOWING THE STRUCTURE AND DISTRIBUTION OF MATERIALS IN AND ADJACENT TO SLIDE, A CROSS-SECTION SHOWING THE RELATION OF THE MATERIALS IN THE SLIDE TO THOSE IN ADJACENT STABLE GROUND, AND THE LOCATION OF THE WATER SURFACE, SUITABLE CHARTS EXPRESSING THE PRECIPITATION AND TEMPERATURE RECORDS DURING AND PROCEEDING THE MOTION, AND A CHRONOLOGICAL RECORD OF THE EVENTS CONNECTED WITH MOTION. THE MATHEMATICAL EXAMINATION OF CONDITIONS, WHERE APPLICABLE, SHOULD PROVIDE AN INDICATION OF THE MAGNITUDE OF FORCES INVOLVED IN THE FAILURE.
