Coastal Protection (DM-26.2), Section 3: Basic Planning

This section covers the basic planning of a coastal project. It begins with environmental considerations, including a discussion and the guidelines and standards that apply, and then covers the functional design of the structure.

It explains the main wave effects a structure must handle: wave runup, including its definition and calculation, wave transmission over or through a structure, and wave reflection and how to calculate it. These effects decide how high a structure must be, how much wave energy gets through, and how much bounces back to cause scour or disturb nearby harbors.
