High Explosive Crater Studies: Desert Alluvium (open access)

High Explosive Crater Studies: Desert Alluvium

From abstract: Crater dimensions have been determined for 23 explosions of 256-pound spherical TNT charges buried in desert alluvium. As opposed to previous work covering depths of burst as great as 6 feet, the work presented in this report extends knowledge of apparent crater radius and depth to depths of burst as great as 30 feet.
