HYDRAULIC PERFORMANCE OF DRAINAGE STRUCTURES, PHASE I AND II

Experiments were conducted on several types of hydraulic structure models important to highway drainage, including curb inlets and culverts. The hydraulic performance of inlets was examined by measuring inlet flow as a function of total curb flow for various slope conditions. Using standard transfer relationships, these data have been converted to full scale predictions of performance and efficiency. The effect of entrance spacing on culvert end section performance was investigated for scale models, but found not to be of special importance for design purposes. Similar methods were used to examine the performance of a proposed 6:1 mitered end section. Results indicate that this type of end section is comparable in performance to the 4:1 end section now in use. A second part of this report is concerned with a description of two demonstration models developed for the Florida Department of Transportation (FDOT), intended to be used for instructional purposes by FDOT personnel. One model was developed to demonstrate elementary concepts of open channel flow and a second model was constructed to demonstrate inlets used for drainage in pavement-curb configurations.
