WebJul 17, 2024 · Equation ( 20) describes the long-profile evolution of an equilibrium-width gravel-bed alluvial river. The dependencies of the variables in Eq. ( 20) are as follows: z = z(x, t) Q = Q(x, t) B = B(z(x, t), t) … WebThe long profile begins steeply near the source and reduces quickly in height as the slope of the river valley reduces , becoming increasingly a more gradual decrease nearer the mouth. For this reason the shape of the long profile of a river valley could be attributed to a exponential function.
