Deltares Conducts Study on Sao Tome and Principe Erosion Issues

Deltares has completed an investigatory study looking at sustainable solutions to coastal erosion in the African island group of Sao Tome and Principe.

The islands are severely affected by coastal erosion in a number of locations, in part as a result of climate change. The study was conducted at two specific locations to see whether a natural approach in the form of sand renourishment combined with dune-building and vegetation recovery is feasible.

Morphological, ecological and socio-economic impact of the sand renourishments

Deltares collected data at the locations, Malanza and Praia Burra, and entered them in models implemented in support to the renourishment and dredging works. The ecological impact was also studied and a monitoring plan of the renourishments was proposed. Support for the solution among the local inhabitants was also surveyed.

The government will take a definitive decision on the basis of the study.

Sand renourishment is a flexible solution for sea-level rise

Alessio Giardino, the project manager, said: “Increasingly, we are seeing governments choosing natural solutions to coastal erosion. The advantage of sand is that it is very flexible. For example, it is easy to adapt it in response to sea-level rise and possible changes in the social structure of the communities (i.e. increase of number of people leaving at the coast). Furthermore, government agencies and the public are increasingly aware of the coastal system as a whole.”

Studies of the impact of climate change have already been conducted in the past

Deltares has been active in Sao Tome and Principe for some time now. January 2013 saw the completion of a study in relation to the impact of climate change for a number of villages in the two islands.

A range of climate scenarios were drafted for the islands in collaboration with UNESCO-IHE and the consequences of the different scenarios were mapped out. Possible adaptive measures were also proposed based on sustainability as the guiding principle.

The exploratory study was conducted for the Ministry of Public Works and Natural Resources of Sao Tome and Principe. It was financed by the Global Environmental Facility and initiated by the World Bank.

3rd International Congress Hydraulic Engineering Structures and Dredging

Russia’s leading maritime industry Media Group PortNews (www.portnews.ru) holds a traditional annual Congress “Hydraulic Engineering Structures and Dredging” in Moscow. 

The two-day Congress includes the 7th International Forum of Dredging Companies and the 3rd Technical Conference “Modern Solutions for Hydraulic Engineering”.

Infrastructure development is among the real sources of Russia’s economy growth. Construction of port facilities and new hydraulic engineering structures on the country’s inland waterways constitute an essential part of all infrastructure projects. It is important to take into account the best international practices to implement these projects effectively.

The program of the Congress will be devoted to the latest technologies for dredging and hydraulic engineering works. Speakers and delegates will refer to real projects to discuss specifics features of dredging works, as well as dedicated fleet and equipment involved.
