Culvert Sizes Needed for Small Drainage Areas in the Central Appalachians
Within the central Appalachians, peak discharge from small watersheds (54 to 96 ac) was well correlated with drainage area for recurrence intervals of 10, 20, and 50 years. Culvert sizes to carry the expected flow rates are tabulated for standard conditions where (1) the water surface at the culvert inlet is the same elevation as the top of the pipe, (2) the outlet is not submerged, and (3) the culvert slope is at least 2%. Culvert sizes are presented for drainage areas in the Central Appalachians between 10 and 200 ac, and the results are tested for applicability in the Northeast. This limited test indicated that required culvert size for forested watersheds increases with latitude north of the central Appalachians. North. J. Appl. For. 5:123-127, June 1988.
