A spiral bay is bounded by two erosion-resistant headlands, as shown in figure. The updrift supply of sediment to the bay Qso is one-half the transport capacity of the waves, Qs. At the location indicated as B, a sand mining operation removes sand at a rate of Qsm, which is smaller than Qso. This sand mining begins at time t = 0. a) Qualitatively sketch the bay planform after it has equilibrated to the sand removal. Discuss the reasons for the characteristics of the altered planform. b) Qualitatively sketch the bay planform after equilibration if the rate of sand mining were equal to Qso. Discuss the reasons for the altered planform. Headland- Point "B" Bay Planform for Qom-0 /05m Q5 Head and Waves A spiral bay is bounded by two erosion-resistant headlands, as shown in figure.
