STORMWATER SIDE ENTRY INLET: A PHYSICAL MODEL STUDY TO EVALUATE PERFORMANCE. FIFTH NATIONAL LOCAL GOVERNMENT ENGINEERING CONFERENCE, SYDNEY, AUSTRALIA, 24-29 SEPTEMBER, 1989

A side entry inlet is currently used in the Townsville City Council urban drainage system to capture and convey surface storm water to underground pipes. Data for determining the required size, number and location of such pits had been inferred from results of model tests in the USA on a different system. An undistorted scaled hydraulic model of the actual modular system was constructed for testing in the Civil Engineering hydraulics laboratory at James Cook University. The performance curves obtained from the tests showed significant differences from those previously used, presumably because the road, gutter and inlet dimensions are markedly different. The results enable informed decisions to be made on tradeoffs between length of inlet opening and addition of deflectors. They also provide quantification of the loss in capture efficiency due to construction deficiencies such as omission, or reduction in depth, of the depression, or omission of the transition segments.
