The report discusses experiments on oblique weirs in an open channel to understand flow behavior and hydraulic characteristics. Different types of weirs were tested, showing complex flow patterns like hydraulic jumps and turbulence. The experiments revealed that emerged flow conditions lead to more turbulence and energy loss compared to submerged flow. Despite differences in weir shapes, similar hydraulic phenomena were observed. Various instruments were used to collect accurate data, including acoustic and electromagnetic velocimeters. The study aimed to provide a quantitative view on energy loss and discharge coefficients for oblique weirs.
