Predicting Maximum and Minimum Aeolian Sand Transport Rates to Profive a Basis for Assessing Management Actions for Beaches and Dunes

This paper presents simple methodologies for predicting rates of aeolian sand transport rates on beaches for the assessment of alternative management actions. The equations of Bagnold (1936), Kawamura (1951), and Zingg (1953) are used to predict таxiтит, тoderate, and minimum rates of sand movement under dry conditions. The Belly (1964) and Hotta et al. (1984) equations are used to correct for wet conditions. Examples of data sources are described, and a protocol or using the methodology is detailed using data for a beach at Wildwood, New Jersey, USA. It is shown that there is reasonable agreement between predicted and observed transport values for the relatively uncomplicated conditions on a flat beach. More complex issues associated with transport in dunes and with other complicating factors presented. Potential applications for dune management and resource protection are discussed.
