This research is designed to improved the analysis and interpretation of shock-wave data in the hydrodynamic region gathered in the past or in the future to monitor agreed limitations on underground nuclear testing. Research accomplishments include: (1) refinement and comparison to numerical simulations and actual nuclear test data of an approximate analytical model of the shock-front radius vs. time relationship for a variety of geological media; (2) assembly of a Hugoniot database for several important classes of geologic materials; (3) investigation--by means of the approximate analytical model--of the nature and physical basis of the insensitive interval discovered empirically in hydrodynamic data taken at US test sites; (4) a rigorous analysis of the conditions under which cube-root scaling is an exact condition in the hydrodynamic region; (5) detailed analysis using state-of-the-art, one-dimensional hydrodynamic numerical simulations of the effects of source parameters on hydrodynamic yield estimation; (6) the development of a state-of-the-art, two-dimensional hydrodynamic code suitable for simulating two-dimensional source and/or ambient medium effects.
