FLUORESCENT COATINGS ON COARSE SEDIMENTS: AN INTEGRATED SYSTEM
Abstract
A wide assortment of daylight and near-UV fluorescent dyes was used in coating formulations which should allow rapid qualitative or quantitative estimate of sediment transport in rivers or on beaches. There is sufficient range in physical properties of the coatings to meet the needs of most studies. Field sediment sampling can be eliminated or supplemented by photometric measurement of marked particle concentration. Field trials were an attempt to test the system's usefulness as an adjunct to beach morphology investigations in progress at Sandy Hook, New Jersey. Difficulty arose, not with the fluorescent sand system, but rather with inadequate, nonphotometric sampling techniques currently in use. Many aspects of beach morphology investigation, such as depth of sand disturbance, sorting, stratification, and particle dispersion, proved amenable to study using coated particles. (Author)
