Collaroy Narrabeen Beach Erosion Time Lapse

thats right. 90% of the erosion during this whole period took place during those 3 days of the first storm.

In the NW Australia, we have huge tides,

huge evaporation and huge dry rivers and lakes.

Tides are up to 12m. Evaporation is up to 4m per year .

Huge 12m tidal erosion can revive old dry once mighty rivers, creeks and lakes,

desalinate the country and change deserts to rain forests to provide more rain across Australia.

we need more energy, food, land, water and cooler climate,

Plenty of energy and HYDROGEN TO RUN YOUR CAR environment friendly.

I wonder if keeping Narrabeen Lakes open to the ocean will improve the sand banks? Alot of sand must naturally come from the lake yeah? I heard they closed the lake so people can walk all the way up the beach.

Also, when you build up to the high water mark you stop normal erosion. You'd assume the beaches over 100s of years would move more inland if they could.

Also, also, i thought they banned future development & sale of this beachfront land? There's been heaps of development latley!
