Multivariate Statistical Models for Predicting Sediment Yields from Southern California Watersheds
Joseph E. Gartner, Susan H. Cannon, Dennis R. Helsel, Mark Bandurraga
2009, Open-File Report 2009-1200
Debris-retention basins in Southern California are frequently used to protect communities and infrastructure from the hazards of flooding and debris flow. Empirical models that predict sediment yields are used to determine the size of the basins. Such models have been developed using analyses of records of the amount of material...
