PEAK DIFFERENTIAL TIDAL PRESSURES FOR ROCK WALL RECLAMATION AREAS

Resumen

Unexpected differential tidal pressures occurred during construction of a 62 Ha reclamation area at Townsville Port. The reduction in tidal flows through a new rock wall structure was in conjunction with installation of a geotextile membrane. Tidal pressures began to displace the geotextile and cover rock. This paper discusses tide data collected during various stages of construction and how it was used for estimating progressive tide differentials. These estimates assisted with forecasting potential issues.
