ACTION OF RAINFALL AND MOISTURE INCREASE TO DEVELOP LANDSLIDES

Abstract

Correlation of landslides and precipitation has long been observed. A lot of landslides ensue in springs following long, wet winters. Cyclic variations of weathering and yearly rainfall are reflected by the yearly frequency of landslides. Shear strength decreases exponentially with increasing water content. Shear strength values of clays are seen to haye decreased after drying wetting cyles.
