<p>The mounting of an inflatable flexible membrane weir to the crest surface (1a) of a dam (1) extending between banks (2) of a body of water, the crest surface being of arcuate shape in cross-section, is enhanced without there being any need for provision of a pedestal adjacent to the dam and extending the entire width of the body of water by positioning at the respective intersections of crest surface (1a) and bank slope surfaces (2a) on the upstream side of the dam crest (1) of a fillet (3), which is a tetrahedrally shaped body having a curved surface lying on the dam crest, its remaining surfaces being flat and including a top surface (3a) extending between crest and bank and a surface intended to abut the respective bank slope surface (2a), both of which surfaces include a curved side which is common to the curved triangular surface. An upstream toe edge of slope (5a) of an inflatable flexible membrane weir (5) is secured along the upstream side of the crest surface (1a) and extends over the fillet and onto the bank slope surface (2a) to be secured thereto. <IMAGE></p> |
