Abstract:Salt tracer is one of the widely used shallow water velocity measurement methods. The Pulse Boundary Model method produces low velocity at short distances from the salt injection position. This study proposes a two-step approach to accurately estimate the flow velocity. Experiments were carried out under three flow rates of 12, 24, and 48 L min -1 and three slope gradients of 4, 8, and 12° at six measurement positions of 0.05, 0.3, 0.6, 0.9, 1.2, and 1.5 m from the solute injection positions. The new method ob… Show more
