边缘波是由水体边缘所限制的沿岸周期波浪运动。它与近岸过程有关，且是折射受限制的重力波，而重力波的水平长度的尺度变化从几厘米至几公里。其周期同入射风浪或更长一点的边缘驻波，是形成近岸环流流型、海滩嘴以及新月形沙坝的重要因子。前进边缘波可以在形成平行于海滩的沿岸沙坝中起着作用。这些推测是很难使用现场资料来试验的，原则上只是得到少量实验室试验的验证。本文评述了这些试验的结果以及特殊问题。
Edge waves are periodic wave motion along the shore limited by the edge of the body of water. It is related to the nearshore process and is a gravitational wave with limited refraction, whereas the horizontal length of gravity waves varies from a few centimeters up to a few kilometers in size. Its period is the same as that of incident waves or a longer standing wave. It is an important factor for the formation of nearshore circulation patterns, beach mouths and crescent shaped sand bars. An advancing edge wave can play a role in forming a sand bank that is parallel to the beach. These speculations are difficult to test using field data, and in principle only get a small amount of laboratory tests. This article reviews the results of these tests as well as specific questions.
