Book excerpt: The Ansonia-Derby project will provide protection for the cities of Ansonia and Derby, Conn., from flooding of the Naugatuck and Housatonic Rivers. The proposed plan for containing the river flows requires about 13,300 ft of earth dikes and 6850 ft of floodwalls, extending about 2-1/2 miles along the Naugatuck River and 2000 ft along the Housatonic River. A 1:120-scale model was used in the investigation and reproduced approximately 4000 ft of the Housatonic River and 16,000 ft of the Naugatuck River. Tests were concerned with flow conditions at bridges and channel transitions, water-surface elevations for selection of grades for the dikes and floodwalls, and velocities for use in the design of riprap to be placed on the river side of the dikes and in portions of the channel. Flow conditions were poor and water surfaces were higher than expected in the upper reach of the project; however, a satisfactory design was developed for this area. Water-surface profiles and bottom velocities were obtained with the final design for both the design discharge and the capacity flow. (Author).
