20. ABSTRACT (^az2t£aua am rmveram afds f/ n*:c»aaazy and Identity by block number) 



This report summarizes procedures for calculating the maximum tidal inlet 

 channel velocity during a tidal cycle as well as the bay tidal range and phase 

 lag (published by King, 1974). Guidance for the application of these pro- 

 cedures to solve tidal inlet design problems for jettied inlets is also 

 presented. The procedures may be applied to some unjettied inlets. A 

 procedure is described whereby the inlet hydraulic response calculations can^ 

 be combined with the appropriate tidal prism-inlet area stability relationship
