A PROPOSAL IS PRESENTED HEREIN TO INITIATE AN ANALYTIC STUDY OF THE FLOW FIELD RESULTING FROM THE INTERACTION OF AN UNSTEADY SHOCK WAVE WITH THE GROUND AND ABOVE GROUND STRUCTURES. THE LONG TERM GOAL OF THIS ANALYSIS WILL BE TWOFOLD, (1) PREDICT THE PRESSURE PULSE ON STRUCTURES AND (2) PREDICT THE FLOW FIELD DUE TO THE PROPAGATION OF A SHOCK WAVE ALONG THE GROUND AND THE RESULTANT DUST ENTRAINMENT THE OCCURS. ALTHOUGH THE ULTIMATE AIM OF THE PROGRAM IS TO FULFILL THE TWO GOALS MENTIONED ABOVE, THE PRESENT PROPOSAL FOCUSES ON DEMON STRATING THE CAPABILITY TO ACCURATELY PREDICT PRESSURE DISTRIBUTIONS BY CONSIDERING THE SHOCK DIFFRACTION PROBLEM, I.E. THE INTERACTION OF A MOVING SHOCK WAVE WITH A WEDGE. AN IMPORTANT FEATURE OF THE ANALYSIS IS THE USE OF NAVIER-STOKES CODE WHICH PROPERLY ACCOUNTS FOR VISCOUS EFFECTS THAT INFLUENCE THE PHYSICAL PROCESSES OCCURING NEAR THE SURFACE.
