Slope evolution and slope stability, Kawarau valley, Central Otago, New Zealand
Summary Slopes developed within the Kawarau Valley in response to Late Pleistocene fluvial, glacial and periglacial processes, with localised slope failures continuing during Holocene times. Rock mass anisotropy within the basement chlorite schists has been a major influence in geomorphic development, and extensive mass movement deposits now mantle the valley slopes. A chronology of events is presented, based in part on radiocarbon dating and pollen analysis, and geological and geotechnical aspects of slope instability are reviewed with reference to particular landslide areas. Slope evolution within the Kawarau Valley has major engineering and environmental implications, and these are discussed in relation to proposed hydro-electric development, roading and land use. Quantitative assessment of the stability of both rock and soil slopes must take account of the complex geological controls of slope development, and investigation methods are outlined.
