Exceedance probability-depth relationships of floods for Maryland streams west of Chesapeake Bay

A procedure is outlined for estimating the depths of floods of specified exceedance probabilities for Maryland streams west of the Chesapeake Bay. Data required for use of the estimating procedure are the stream's location in one of three flood-depth regions and the drainage area. Regression equations developed for depth estimation of the 50-, 20-, 10-, 2-, and 1-percent floods have standard errors of estimate of 19 to 25 percent for Region I, 22 to 36 percent for Region II, and 19 to 24 percent for Region III.
