The stability of abutment slopes, if they are steep enough to slide, depends on trends in both long term and short-term rainfall. The risk of sliding can be related to these trends in a manner similar to the determination of design floods. Slides may have moved to a more stable position when climate was worse, giving a reserve of stability. Speed of movement strongly influences danger. Reactivated slides should not move rapidly but first-time slides may do so. Risk of sliding could be estimated by limited monitoring. Prophylactic remedial drainage works could then be used to control risk.
