Let us apply the Culling model to the progradation of a river delta into a quiet basin with a horizontal flow. Sediments are supplied to the delta by the river forming it. Sediments are deposited near the landward edge of the
Illustration of the one-dimensional model for a prograding river delta. It is assumed that the delta progrades seaward at a constant velocity U0; its position at successive times t1 to t4 is illustrated. The height of the prograding delta above the basin floor is h. delta and are transported down the front of the delta by creep and shallow landslides. Our simple one-dimensional model is illustrated in Figure 4–60.
The delta front is assumed to prograde forward at a constant velocity U0 and its position at successive times t1, t2, t3, and t4 is shown. We utilize the approach given in Section 4–19 to solve this problem.
