Walls don't last

For the sake of memory and history, a piece of leftover Berlin-Wall.

The Coastal walls and the Berlin wall

(Author: Hamsen B Paramahamsa MSc)

The Berlin Wall is gone and is history. It took more than three decades to break it down. Now few remnants are left for the memory's sake. The warning it gave that walls don't solve problems, but essentially worsens them, has not entered all fields. Tragically today, one witnesses the coastal wall construction in full swing. They claim as the only solution for the problems on the coasts, worldwide.

One cannot find a way to prohibit it. Worst are the coastal scientists, as far as I can observe, from the UK and Australia. Yet, in many other countries the blunt phenomenon of the Coastal-wall construction could be witnessed.

I wish there were a few who understood the science in Coastal Erosion and would dare to refuse to accept the theory of the coastal-wall construction, though they must sacrifice their profession.

The theory is: "Sea Level Rise" is the cause for the coastal erosion. This theory is wrong in its core. The coastal erosion proceeds from the land into the sea. The result of which is the sea level rise.

The sea level rise submerges a landmass but not erodes the landmass. The rise of “sea level” and “coastal erosion” are two different things.

Presently, the sea level rise is being measured by many stations, using all kinds of technologies including satellites. And they say it is about one cm per year.

On the coast, the rise of sea level and its lateral coastal invasion depends on the gradient of the coast. If the gradient were about 45° cm the lateral invasion of the coast will be 1cm per year. A negligible amount. In addition, there are land-level dropping factors on the coast, which makes the measuring of the 1 cm lateral invasion of the coast by the sea a burden.
