Overview

Notes

AHD @ G6 about 0.96  @  13:58  board covered with silt

Observations made during hi tide & storm surge - wind from SE  8-9 along beach but even stronger turning down channel  Not possible to use Gp1 site so taken from below.

Waves entering from high sea combined with a very high tide. No fresh discharge only shallow salt return over high sand build up in channel. Waves going up to base of dunes all along beach & channel. Entering very wide at mouth & completely across channel. SW swell with over 8m waves strongly impacting east end of beach creating very strong longshore drift & backwash. Waves overtopping high part of beach about 50m from west cliff then turning west & around into the channel meeting incoming waves from SW swell also going down  creating an extremely strong N-S backwash - also whirlpools at start of estuary, this action has left significant depressions in the sand . The wind action has also sent large amounts of sand from the beach down the channel & into the estuary
