This is much more complex than the design of a sea wall.

Wollongong, Shellharbour and Shoalhaven have all had assessments done on the likely loss of land along our beaches. You can view these reports on their websites. Forecasts are given based on sand loss and deposition rates with the likely wave run up and sand loss areas forecasted for 2050 and 2080/100 - some forecasts including global warming effects. A lot of loss is predicted and many houses are at risk if not designed properly. The sea wall is meant to have been designed for this likely loss. So it is not the design that is the issue - but the fact the wall reclaim land that will reduce the effective width of the sandy beach - but loss will also occur due to the future loss of sand due to wave run up and sea level rise - unless the council replenishes the beach like on the Gold Coast - or Kuta beach in Bali - many places are being affected. Council here is trying to provide more usable land - filling and grassing it and protecting it from erosion by a sea wall - and the down side to this is partial loss of the sandy parts of the beach. Elsewhere it has revegetated sand dunes and protected them but blocking public use. Sand deposition and erosion modelling is a specialist area of marine costal science - https://www.facebook.com/share/1BVkKz4Pu4/?mibextid=wwXIfr

A geo-technical engineer has cast doubt on the design for Stage Two of a seawall at North Wollongong beach.

It's the only beach patrolled year-round in the Illawarra and highly popular with tourists wanting a beach experience.

Geo-technical engineer, Kourosh Kianfar, from KMK Geotechnics says the current design with a wall closer to the ocean will accelerate the removal of the sand.

“That means we are making the beach narrower and narrower, and this structure is permanent so in a few decades we will not actually have much of the beach actually left, potentially,” Mr Kianfar said.

A Wollongong Council spokesperson said Stage Two was approved after extensive consultation and they recognise the new wall will replace some of the existing sandy area of the beach.

At Terra we have been thinking about the impact of western lifestyles on our planet. So we are developing and expanding our skills to help our clients adopt a circular approach to their lifestyles, businesses and communities. The key parts of a circular encommy take the three Rs and expand the to 7 including the following:

Rethink
Refuse
Reduce
Repurpose and Reuse
Refill
Recycle
Rot

We will be adding this as a new business line and going to expand it over time. If you’re interested in working with us in this space - reach out to us. Small steps add to big progress - if we all play a part.

Some interesting layering in these subsoil drains at Deborah’s place today. Nice carbonaceous (coal like) layers , a visible base of slip in part of the profile - and a lovely thin bright white undulating layer - most likely a historical layerr of ash that fell when we had active volcanoes off the coast line - now forming a completely weather Tuff which can be found in close proximity to coal seams within the Illawarra Coal Measures.
