| Description |
The 1st river mouth closure for the season occurred on the 25/12/2014. At 09.15 the estuary height was 1.15mAHD, the berm clearance was 0.15m and the sea conditions were a smooth moderate swell. The estuary height slowly increased over 4 days to 1.46m at 09.00 on the 29/12/2014 with a berm clearance of under 0.1m. At 10.00 on the 30/12/2014 the river mouth was open and flow was out. The estuary height was 1.28m. The river water was just overflowing the top of the berm. The early season river mouth closure for the Barham was predictable in light of the dry spring / summer weather and consistently low river flow. In October the lowest estuary height observation was 0.88mAHD. In November and December the lowest observed height was 0.96mAHD. These very high base levels were as a result of a large sand build up inside and at the river mouth. At 19.00 on the 31/12/2014 the estuary height was back to the December base level of 0.96m. |
