Long term review of slope stability for 400 m high slopes in soil and rock adjacent to residential and plant areas.  Extensive investigations including soil and rock slope failure evaluations since 1971.  Design and performance monitoring of 300 m high anchored slope in slate.  Development of specialised high resolution monitoring techniques for large slopes.  Study of current 50m ton failure in weak ultrabasic rocks including large scale remedial drainage measures from underground.  Prediction of long term slope performance.  Estimation of long term movement limits.
