Description: Technical note
INTRODUCTION: For the design of most coastal projects, a knowledge of the tidal variations at a specific site is required since the minimum and maximum expected water levels are important design considerations. In addition, it is necessary to relate these water level fluctuations to .a fixed land point of known elevation. Such a point is called a bench mark. This information is needed to design such projects as coastal protection structures (including beach fills), harbor improvements, and navigation channels.
