|Abstract:||The US Army Engineer Waterways Experiment Station (WES) conducted dust obscuration measurements at Fort Carson, Colo., in April and August 1983 to demonstrate the validity of existing models to predict crater volumes produced by a given explosive charge and to use models developed by the Atmospheric Sciences Laboratory (ASL) to predict the mass of dust in clouds formed from the explosions. It was found that apparent craters formed agreed well with the "1.111 Power Law" used in EOSAEL 82 (COMBIC) developed by ASL. Cloud masses were calculated using techniques developed by ASL and a contractor, PEDCo, Inc. (now PEI Associates). Generally, results obtained at Fort Carson showed that from 2 to 5 percent of the excavated soil mass would be found in a dust cloud after approximately 10 sec had elapsed from detonation. Improvements in sampling techniques, particularly those characterizing the vertical nature of the cloud, are recommended. Since the composition of the cloud can vary greatly in a few meters of downwind distance, different sampler types should be used and should be positioned as close together as practical to determine differences in the respective samplers. Other recommendations concerning the conduct of future tests are included.|
