Sensitivity Analysis of Adjustable River Surf Waves in the Absence of Channel Drop

Most artificial river wave technologies require a drop in the riverbed to generate recreational surf waves; herein new technology is introduced that can be used on flat bed. The mechanism includes an adjustable ramp, transition and kicker, which independently manipulated wave. A 3-D numerical model of described developed based prototype Kananaskis River Alberta, Canada, calibrated by means physical data. Numerical experiments are conducted demonstrate sensitivity geometric features each element structure different hydraulic conditions such as flowrate tailwater depth. Results presented dimensionless form generalizable describe behavior. It shown ramp slope, heaviest most expensive structure, has minimal effect profile, while depth, kicker geometry position significantly augment accelerate
