Climate change and the expected rise in the sea level mean that coast management requires our full attention. Coastal erosion results not only in the loss of land to the sea, but also in the reduction of the freshwater reservoirs under the dunes and therefore an adverse impact on flora and fauna.
Beach nourishment is probably the best management tool that protects and controls coastal development without degrading the beach. Preserving or restoring a sandy beach has direct beneficial impacts on recreational opportunities and property values.
Gidrostroy Ltd. applies three methods of protecting the coast in the most environmentally friendly way.
Pumping sand on the beach using a floating or submerged pipelineThe Rainbow Method – pumping dredged material directly out over the bow of the ship to the fore shoreAnd dumping close to the shore using split hopper dredgers
These methods are highly suitable for the natural variation in coastal profiles. Each of these techniques, alone or in combination, are also adaptable to changing seabed profiles, currents, sea state and sand quality for maximum effectiveness.
Maintainence or capital dredging
The periodic removal of shoals or sediments from existing navigational channels, berths, swinging moorings etc in order to maintain an appropriate safe depth of water for navigation, construction or operational purposes.
Today, more than 60 percent of the world's six billion population lives less than 100 kilometers from open water. Of the world’s 19 megacities - those with over ten million inhabitants - 13 are built in coastal zones. Water is both a threat and an opportunity to mankind.
The world population is predicted to grow to 8-10 billion people in 2050. This will create enormous challenges for transporting people and goods in a safe, economic and environmentally acceptable way. Waterborne transport is slated to grow explosively; overpopulation, industrial development and the need for environmental protection will place new pressures and demands on the world and its infrastructure.
