Blackstone River Flood-Control Project at Woonsocket, Rhode Island: Hydraulic Model Investigation
A 1:50-scale model was used to study flood-control plans for a reach of the Blackstone River at Woonsocket, Rhode Island. Plans for vii this reach included channel improvement, replacement of the existing fixed-crest industrial dam, and excavation below and under an existing masonry arch bridge. The purposes of the study were to check the hydraulic performance of the proposed Woonsocket Falls Dam and approaches, determine the most effective treatment of rock excavation downstream of the dam and under the South Main Street bridge, and develop such design modifications as might be found desirable. The fixed-bed model reproduced a 2225-ft reach of the Blackstone River, the proposed new dam, and bridges in the reach. It was determined from the investigation that the proposed design would result in less head loss below the dam and under the South Main Street bridge than had been computed, resulting in lower water-surface elevations upstream of the dam for the design discharge. The results also indicated that the rock excavation below the dam could be reduced without affecting water-surface elevations above the dam, and that the head losses between the dam and the bridge could be increased appreciably before flood stages upstream of the dam would be affected seriously.
