Sand dunes represent the most significant aeolian land features in Kuwait. In this study, field and laboratory work were undertaken to describe the Kuwait dunes, identified as crescent-shaped dunes, in terms of morphology, sedimentology and mineralogy. The following relationships between the height (h), width (W) and length (L) of the dunes were determined: L = 15.2 + 14.9 h, W = 15.5 + 6.7 h, and W = 14.96 + 0.3 6 L. The studied dunes are all unimodal, with the grain size mostly varying between medium to fine sand. The non-opaque heavy minerals are-more common than opaque ones, and quartz, carbonate minerals, and feldspars dominate the light mineral fraction. The annual rate of movement of most dunes of Kuwait exceeds 20 m/yr.
