Five models for predicting rates of aeolian sand transport were evaluated using empirical data obtained from field experiments conducted in April 1994, at a beach on Inch Spit, County Kerry, Ireland. Measurements were made of vertical wind profiles
(to derive shear velocity estimates), beach slope, and rates of sand transport. This paper describes the experiments and the resulting comparison of the models. The influence of sediment moisture content appeared to be the critical factor in degrading model

A computer program has been developed to simulate two- or three-dimensional topographic change associated with aeolian sediment transport. This program includes a number of models and provides for interactive selection of a desired model combination
(s), to allow for comparison between model predictions. Examples of results are presented, and considerations regarding the simulation procedure are discussed. Areas where further refinement is needed to improve correspondence with reality

Results from a three-year study are presented that integrate field work (in the Negev Desert of Israel), physical modeling (wind-tunnel testing at UC Davis), and numerical solutions of grain trajectories to model and explain sand transport over
