Abstract: In the design of hydraulic structures for flood control, it has become standard practice to employ the average return period of a flood as the design event. This study introduces an analogous index for the design of a water ...

Abstract: A regional hydrologic model is developed for estimating flow‐duration curves at ungauged and unregulated basins in Massachusetts. Flow‐duration curves often exhibit complex shapes, requiring probability density functions ...

Abstract: L-moment diagrams are constructed for annual minimum, average, and maximum streamflows at more than 1,455 river basins in the United States. Goodness-of-fit comparisons reveal that the generalized extreme value (GEV), ...

Abstract: Substantial evidence exists to warn the civil engineering profession of impending shortages in the qualified labor force in the coming decades. ASCE has set ambitious goals for growth in the number of civil engineering ...

Abstract: Although a vast amount of literature exists on the selection of an appropriate probability distribution for annual maximum floodflows, few studies have examined which probability distributions are most suitable to fit to ...

Abstract: Flood‐plain delineation in ice jam prone regions is in its infancy. A methodology is introduced for incorporating the risk of ice jams into flood‐plain delineations in northern regions of the U.S. The distribution of flood ...

Abstract: Estimates of annual streamflow volumes are needed in many different types of hydrologic studies. Usually a streamgauge is unavailable at the location of interest, hence regional methods that relate streamflow to readily ...
