Abstract: If ocean outfalls are to function effectively it is necessary that seawater be fully purged from the system. Consequently a basic design requirement of an outfall is that it has purging capability. This paper describes model studies designed to investigate the detailed nature of the purging process in outfalls with high risers. Both purging of seawater from the outfall and its subsequent intrusion into the outfall following cessation of effluent flow were investigated. The results of the study are presented in non-dimensional terms and are compared with existing theoretical models.
