In 1981, as part of the U.S.-China Protocol for Scientific and Technical Cooperation in Earthquake Studies, two arch dams in China--Xiang Hong Dian and Quan Shui--were excited by rotating mass shakers to measure vibration properties and the resulting hydrodynamic pressures. The measured data were then compared with predicted values calculated by an enhanced version of the previous Arch Dam Analysis Program (ADAP), developed for the U.S. Bureau of Reclamation in 1973. The research provided a unique opportunity to verify, enhance, and modify the previous program. The present version of the program is called EADAP, Enhanced Arch Dam Analysis Program. INCRES, INCompressible REServoir, is the name given to the new version of the previous subroutine, RSVOIR, which was developed to approximate the hydrodynamic effects of dam water. This report is intended as a user's manual for the EADAP and INCRES programs. The most important features of the program are described: the system idealization, element types, and analysis procedures. The input data and the output results are discussed, and a sample problem is presented.
