Abstract : Thirty-seven 1-lb spheres of TNT were individually exploded at various depths of burst in a sand test pad. Of these, 19 detonations were conducted in a dry sand-medium and 18 in a wet-sand medium at comparable depths of burst. The craters produced were accurately surveyed by using a bridge and probe assembly. The result of these crater surveys are shown on topographic maps. In addition to topographic measurements, volumetric measurements of the craters, ejecta measurements, and medium density, moisture content, grain size distributions are presented. The experimental procedures, equipment test area, and sand medium are discussed in detail. The comparison of crater characteristics of wet- and dry-sand environments are discussed and the results presented in tables and graphs. In addition to the crater characteristics, the formation of intracone structures, shock-agglutinated missiles, and the reduction in size of the sand grains composing the medium are discussed.
