| Description |
Saturday 18/04/2015 at 9.50 the river mouth is open and moderate seas are flowing in. The estuary height is 0.96m. Monday 20/04/2015 at 08.06 the river mouth is closed, the last high tide covered all of the berm. The sea is moderate, the berm clearance is 0.23m and the estuary height is 1.30m. Thursday 23/04/2015 at 16.15 the berm clearance is 0.13m, the estuary height is 1.565m and the high tide waves only crossed the berm at the RM. Friday 24/04/2015 at 11.00 the estuary height is 1.60m. Saturday rain. Sunday 26/04/2015 at 09.20 the river mouth is open. The RM appears to be freshly opened overnight. The estuary height is 1.06m. The river water is free of sediment. Monday 27/04/2015 the estuary height is 0.95m. The last 2 river mouth closures and river mouth opening have continued this autumn's trend of closure with the high high tides; but the berm heights have not been high enough to keep the river mouth closed until the next fortnights high high tide cycle.The river flow has been consistently low to moderate. This season the trend of the estuary maintaing high water levels [above 0.9m] when the river mouth is open I have found interesting. I am not sure of the reason; it may be there is a lot of accumulated sand in the bottom 200metres of the estuary or that the river mouth is further north. |
