A culvert is a structure that channels water past an obstacle or to a subterranean waterway. Typically embedded so as to be surrounded by soil, ...
The bridge ran from the northern edge of Main Street in Henderson to the low water mark on the Indiana side, resting on 15 stone piers. It was designed to carry two 118,000-pound (54,000 kg) engines followed by 60,000-pound (27,000 kg) coal tenders, and its maximum uniform load capacity was 2,500 pounds per foot (3,700 kg/m).
The bottom of the culvert will have baffles to retain materials and create a low-flow channel to aid fish migration. Flows up to 600 cubic feet per second (17 m 3 /s) will not be restricted, but greater flows will be limited by a control structure, so that the excess water will be stored in the reservoir. [19]
The NBI can classify bridges as "structurally deficient," which means that the condition of the bridge includes a significant defect, which often means that speed or weight limits must be put on the bridge to ensure safety; a rating of 4 or lower on any of items 58, 59, 60, or 62 (deck, superstructure, substructure, and culverts, respectively ...
The native white-clawed crayfish was found to be living in the culverts under Pocklington town when action was being taken to remove gravel and silt from the beck. [34] Further downstream is the Melbourne and Thornton Ings SSSI , which supports several plants including reed grass, bladder sedge, reed sweetgrass, marsh stitchwort and tubular ...
A channel with a proposed capacity of 1,060 cubic feet per second (30 m 3 /s) was proposed, but arguments about the cost of such a scheme resulted in the capacity being lowered to 600 cubic feet per second (17 m 3 /s). However, the bridges and sluices were either built to cope with the larger flow rates, or made so that they could be easily ...
