ABSTRACT
Among the many forces to which hydraulic structures are exposed, only the forces induced by flow incident or past the structure will be treated in this monograph. The inclusion of such related subjects as forces due to waves or forces due to earthquakes or explosions would have required a separate monograph. Hydrodynamic forces are commonly subdivided into a time-averaged mean part and a fluctuating part. Fluctuating forces can be induced by a variety of basically different excitation mechanisms. Moreover, the IAHR Editorial Committee of the design manual intends to bring out another series of monographs in the near future which will serve the practising engineer as an application index. On all subjects of the design manual, including hydrodynamic forces, research is being performed so intensively and new practical experiences are accumulating so rapidly today that it is impossible to present material in a final form.
