Dear Water Friends,

We like to thank Prof. Marcel STIVE for his passionate, inspirational and outstanding lecture at our water club meeting on last Monday 20 May 2013. He narrated the evolution of coastal engineering measures in the Netherlands over the past centuries and showed the various different policies applied in the Netherlands to cope with floods, land subsidence, demography, industrialisation and climate change effects in the 21stcentury. Many lessons could be learned from this long Netherlandsexperience.

Generally speaking, the coastal safety level in the Netherlands can be associated with a disastrous event of once in every 10,000 years (probability frequency). For inland rivers, this level is lower, say 1:1250 years. Hence, in Holland, the people are NOT living with floods, the people are well protected against the floods. In Vietnam Mekong delta, this frequency is practically 1:1, hence every year mild/strong flooding. In Bangladesh, the safety norm is 1: 100 years. This being said, these figures do not say anything about which delta is more/less vulnerable than which delta……it depends much on the expected economic assets damage and the scale of loss of human life, but the Holland delta and Mekong delta are similarly vulnerable! People in the Mekongdelta live with floods, in an intelligent way indeed. How we go to the more industrialised future from here? Hence, there is a huge difference in ‘safety awareness/perception’ between Hollanddelta and Mekong delta.

He further addressed/recommended the novel concept/approach of risk-based design, whereby risk of groups of populations and/or cities, rural communities etc is computed/quantified and then used as input to formulate and to make well-balanced policy decision, per geographical area. The Netherlands government, viz. Rijkswaterstaat agency has been always at the forefront to anticipate and introduce innovative designs into policy-making to cope with the ever increasing risks of water/environment disasters in the future, e.g. in the densely industrialised and densely populated coastal belt of the Netherlands. An innovative and forward-looking solution for a sustainable (and cost-effective) coastal protection system of Holland coast has been invented, so-called Zand Motor, Sand Engine, Moteur de Sable (click at the website links here below). This system is now working and is being monitored closely. See attached photos of sand engine.

This innovative concept is absolutely applicable/transferable to the coast of Vietnam! We do hope that the advanced and innovative concepts of Marcel Stive may find its way into the practice of sustainable and cost-effective coastal protection in Vietnam and wider Asian region. Prof. STIVE had also presented his ideas at the Symposium Delta2013 Dialogues last week, jointly organised by USA, the Netherlands andVietnam.

We hope that these innovative ideas may contribute to find a long-term vision for the sustainable and cost-effective development of the Mekongdelta as well. We apologise for sending you so many cheerful photos of the water club meeting. We welcome any contribution from Vietnamscientists and researchers on similar or related coastal engineering innovations.

Best regards,
SCT: Chúng ta suy nghĩ và hành động gì, khi những nhà khoa học Quốc tế quan tâm, lo lắng thực sự cho môi trường và các nguy cơ cho người dân Việt Nam. Trong khi một số đại gia trong nước vẫn tìm mọi cách vơ vét tài nguyên: đất đai, rừng, khóang sản...bất chấp hệ lụy môi trường cho cộng đồng!??
Rất cảm ơn sự chia sẻ của Miss. Hiền và chúng tôi xin đăng lại các hình ảnh do cô cung cấp.
