Sand Management in Hook-Shaped Bays
Monitoring, forecasting, and project design and implementation, are the technical components of a coastal sand management program. Forecasting is employed to estimate future beach performance when human interventions are proposed or if natural conditions are likely to change. Proactive management through forecasting heads off serious problems and cuts costs in dealing with them. By focusing on anticipated change and its consequences, it provides a technical justification for decisions. Empirical relationships based on prototype measurements can be a powerful forecasting tool. Examples illustrate how these relationships could have been used to predict beach change in hook-shaped bays when breakwaters and a jetty were constructed. Hooked bays are everywhere. In central and southern California they retain 40% of all sandy beaches. Their sand resource can be managed as a unit because the entire sandy shoreline adjusts in a predictable way to an alteration in the retaining structures (headlands, reefs or stream deltas) or to a change in sand supply.
