hydraulic structures installed in open-channels used to control the flow of
water and measure the discharge. In this study, the flow over a broad-crested
weir in open-channel was experimentally and numerically modeled. Experiments
were carried out in a channel with a length of 1.5 m and a width of 0.055 m
under five different flow rates. In each experiment, water depth and flow velocity
in flow direction were measured using a pitot tube. </span> <span lang="en" style="font-size:12pt;font-family:’Times New Roman’, serif;" xml:lang="en">Numerical model was developed using SimFlow

numerical model were compared to experimental values. There is generally a good
agreement between experimental and numerical results. Relatively small errors
in velocity profiles are observed in higher discharges. </span> <br />}, number={2}, publisher={Sakarya University}
