River mouth photo 20 July 2019

The drone photo of the river mouth, taken on 20 July 2019, shows the effect of removing the high-angle groyne.

Blair, who made the image, said:

The area near where the river enters the sea – could not be rendered as it did not have enough cross reference points to match on. Active water bodies are notoriously difficult to produce aerial imagery.

Always best to fly for photos at low tide.

[This photo] does show the difference in the rock walling and where the channel funnels out to sea.

River mouth photo 24 April 2019

We’ve asked a local drone operator to frequently take photos of the river mouth for our archives. Such photos could be very useful in future if we’re trying to make a case to a Council, for example. Here’s the first photo, acquired 24 April 2019.

By doing a measurement on Google maps, the river seems to travel about 370 metres south from the tip of the groyne, as seen in this photo, before turning seaward.

We’re hoping to get several such photos each year, and will post them here for all to see.
