A regional flow duration curve (FDC) model is under development which relates daily streamflow at 166 unregulated basins in the northeastern U.S. to watershed and climatic characteristics. Fennessey and Vogel (1990) review regional FDC models. The development of a regional FDC model requires an assumption regarding an appropriate probability distribution for daily streamflow. This study describes the use of regional probability plot and L-moment goodness-of-fit procedures for selecting an adequate probability model for daily streamflow in northeastern U.S.
