Magnitude and frequency of floods in small drainage basins in North Dakota
Orlo A. Crosby
1975, Water-Resources Investigations Report 19-75
This report describes methods for estimating flood-peak discharges having 2- to 50-year recurrence intervals on North Dakota streams draining less than 100 square miles ( 259 square kilometres).
