Regionalized partial-duration balanced-hydrograph model

For design problems where annual-event analyses are inappropriate, such as in the case of channel scour due to floods above a threshold, multiple-event analyses with partial duration series should be used. A procedure for calibrating a partial-duration, balanced-hydrograph model for regional design work is presented. The model can be used either as a series of synthetic storm events or as part of a simulation model, Data from Los Angeles were analyzed to develop a model for ungaged urban watersheds in southern California.
