Interpretation of damage to coconut palms, motu and reef-flat structures together with other directional indicators show that hurricane Bebe passed to the east of the atoll. A model showing wind and water motion associated with the storm
-fill deposits. The first two types were attributed to the morphodynamic erosion zone, while the other three, to the accumulation zone. The course of morphogenetic events in the phase of the disappearance of the flood wave during the last water flow
evidence for alternation between wet periods when high water levels prevailed and dry periods with low water levels during which lunette building occurred. The evidence has been interpreted as indicating major changes in climate in the history of the lake
Beach erosion is often associated with sea-level rise, sediment depletion or variation in wave conditions| however above-normal rainfall can cause beach retreat by increasing water-table elevation on the fore-shore. On Stanwell Park beach (New South

and sediment loads have been drastically modified, and sedimentation has accelerated in many estuaries and deltaic areas, as well as locally in coastal waters off river mouths. The pattern of impact is traced in each of the river catchments, and at and around
