Description |
Strong Easterly winds dominate the weather this day. A sea in turmoil with rough conditions from the East. The estuary however was not excessively affected; the estuary staff read as 0.7m at 11.00, 0.96m at 15.20 and 0.70m at 17.00. The still water tide reading in the harbour at 15.30 was 0.84m AHD; not much below the height in the estuary. The great effect of the Easterly wind storm was to the Marengo end of Mounts Bay [the other end of the beach from the Barham river mouth]. The erosion to the foreshore at Marengo was extensive and severe. The walking track, the G.O.Road and underground services are now vulnerable if there is further erosion. The last month has seen the effects of 4 different weater events. June 21st rainfall and a river flood helped by a high tide. July 5th an extreme tide creating very high water levels in the lower estuary. July 9th massive westerly swells elevating the estuary well beyond the still water high tide level. Lastly this Easterly wind storm which had only minor effect on water levels in the estuary, however if it was a common occurrence it might erode the dune system and make a river outlet at the Marengo end of the beach. |
