The successful implementation of structural and nonstructural solution to problems of shoreline erosion is greatly facilitated if the accumulation and analysis of data sets are accomplished within a design framework which has both theoretical validity and practical application. An inventory of beach resources based upon breaking‐wave energy and beach mobility is presented as a basis for a beach classification system. This method should be used with existing inventories compiled by the U.S. Army Corps of Engineers. A simplified means of determining changes in beach position and slope is suggested; this will facilitate gathering data in a daily time series at numerous locations by a minimum number of people. Examples of how the inventories may be conducted and a sample classification system are presented for selected portions of the shoreline of New Jersey.
