Notes

Flow is very slow at the estuary mouth. Berm is extending into the estuary. Sand cliffs are reforming mid-beach (1m high). Longshore drift is moving sand back into the estuary mouth at the entrance. Channel is shallow at the entrance (2m wide) against cliffs, not much sign of any discharge to the ocean, but there is a lot of 'sand stir'. Sea grass exposed in the estuary, some rotting with algae attatched on the east side of estuary on the waters edge.
