Sand movement by wind

摘要: Sand movement on the coast by wind action can be a major factor in some areas, yet very little is known about basic mechanisms of wind. With growing use artificial placement sand material for beach restoration and protection, area shoreward waterline has become more matter concern. The need greater knowledge this recently been emphasized proposed plans rehabilitation vast offshore island areas along eastern seaboard. This report discusses earlier experimental results tunnels, describes compares obtained from new tunnel tests. Work another investigator, directly related to author's work, included an addendum. latter work extends investigation smaller size range suggests that different relationships threshold shear velocity obtain distributions. Of particular interest are tests influence moisture content movement. date clearly demonstrate as increases, value may also materially increase. Quantitative expression effect obtained.
