A sharp-crested weir is the simplest type of weir and is mainly used for discharge measurement in open channels. The surface profile of an ogee weir also is designed based on the lower nappe profile of the free jet passing over a sharp-crested weir. In the current study. influences of sedimentation on the discharge coefficient and lower nappe profile of a sharp-crested weir were exper... https://www.jandroutboard.com/product-category/trucks/
