Description
A side weir is a structure installed along the side wall of a channel, serving multiple purposes, such as raising water levels for irrigation and drainage and diverting excess flow from rivers or channels during floods. Most studies have focused so far on linear rectangular and labyrinth side weirs, with relatively limited research conducted on side Piano key weirs. In this paper, an experimental and numerical simulation was performed on an A-type rectangular side piano key weir and a rectangular sharp-crested side weir. The diversion discharge of Piano key side weirs was within the range of ± 10% with numerical results. The diverted discharge over the rectangular side piano key weir was 1.5 to 6.7 times greater than the linear rectangular side weir. Water surface profile and velocity variations along the rectangular side Piano key weirs were also investigated experimentally and numerically.
