Hydraulic Characteristics of KDOT Flume Inlets

B. M. McEnroe / C. B. Young / G. P. Athey

Hydraulic tests of model flume inlets were conducted in the hydraulics laboratory at the University of Kansas. The objectives of these tests were: (1) to determine the hydraulic characteristics of KDOT's standard flume inlet for a roadway with a shallow gutter, (2) to investigate possible design changes that would improve the hydraulic performance of this inlet, and (3) to develop a new flume inlet design for a roadway with a 102mm (4in) edge curb and determine its hydraulic characteristics. The flume inlet and a 24m (80ft) length of roadway were modelled at one half scale. The flow intercepted by the inlet and the flow that bypassed the inlet were captured and measured. Tests were run with the roadway set at all possible combinations of six longitudinal slopes (0.5%, 1%, 2%, 3%, 4% and 5%) and three cross slopes (1.56%, 3% and 6%).
