HYDRAULIC DESIGN CURVES FOR KANSAS STANDARD DEPRESSED CURB INLETS

Experiments were conducted on a 1:4 scale roadway model 40 ft. long and 6 ft. wide with a Kansas Type B curb and gutter section. Six inlet models were tested. They are four Kansas Type 22 curb-opening inlet with length equal to 6 in., 12 in., 27 in. and 42 in. (2 ft., 4 ft., 9 ft., and 14 ft. in proto-type), the Kansas Type 12 Combined inlet and the City of Topeka Type II-P combined inlet. Each inlet was tested on thirty-three different combinations of longitudinal and transverse slope to determine the intercepted flow at various total discharges. Three transverse slopes, 1:64, 1:48 and 1:32, were used. The eleven longitudinal slopes varied from zero to 0.08. Hydraulic design curves for the prototype inlets are presented and recommended for implementation.
