Description :
This paper deals with the determination of debris recharge rates in debris-flow channels based on knowledge of debris storage and the elapsed time since the last debris flow. Data are obtained from coastal British Columbia and a relation is obtained across a sample of basins with similar terrain and climatic conditions. It is also demonstrated that encounter probabilities in weathering-limited basins cannot be calculated using traditional methods and may have to be adjusted depending on recharge-time correlations.
