The effect of flow acceleration and deceleration on velocity, von Kármán constant, Reynolds and normal stress distributions under incipient motion were experimentally investigated in this study using eight positive and negative bed slopes (± 0.7%, ± 0.9%, ± 1.25% and ± 1.5%) and three uniform sedime...
