Mr. Sanneh,
Denmark mentioned I want to add that there is a dane who has "invented" a
new method to preserve the beaches along the coastline in Denmark with heavy
erosion. It´s very very interesting and most of all, it´s cheap. The man dig
plastic-pipes into the sand over a certain area of the beach, one end some
feet deep and the other end will stay one-two feet up over the beach. And
within weeks the sea start to "deliver" the sand in that area instead of
taken it out into sea. My english is not good enough to explain the theory
behind this coastal preservation method, but it seems to be effective. Some
places the beach has grown from 10 meters wide up to 50 meters wide within
months.
Maybe you should try and get more information from Denmark on the project.
Regards From Asbjørn Nordam
