Thirteen dynamic interface problems have been documented with a detailed discussion, solutions considered and/or applied, and identifiable shortcomings. Recommendations are made for future research funding in five specific areas. The appendixes provide the detailed documentation for each of the dynamic interface problems. (Author) 收起
