A Paradigm shift from "Storing flood waters in inland dams and reservoirs and natural discharging of river flood waters into the Ocean" to "Storing river flood waters incoastal reservoirs in,or close to, the sea using downstream reservoirs"

Despite water covering about 70% of the Earth's surface, fresh water for consumption is not as plentiful.Less than 3% of all the water on earth is fresh, most of which is in the ice caps and glaciers, with only about 1% of all fresh water being accessible surface water! More than a billion people lack access to clean water and about 3 billion people lack the same for about three months in a year. Many large cities in the world are facing a situation of 'water stress', According to the Unites Nations, global demand for fresh water will exceed supply by 40% by2030. The main reasons for this areclimate change, human behavioural change and population growth. Mostcivilizationsin the history of thehuman race flourished in areas where abundant water was available.Now, it seems that there is enough rainfall on our planet to support all humanity, but it is unevenly distributed and a good part of it comes during heavy storms and it is lost to the sea. Due to climate change rainfall events have become more intense and sporadic and as all this happens quickly,the majority of theseflood watersflow through streams and rivers intothe ocean and mix with salt water, thus getting lost as a water resource. A water crisis in many parts of the world can be prevented by starting to regard thelarge volumes of water flowingto the oceans during floods asa valuable water resource. Coastal reservoirs(CR) represent a paradigm shift in the history of water resources management, from storing flood watersin inland dams to storing freshwater in "downstream reservoirs", located inestuaries close to the sea. I have the fortune of being in the position of patron of a new society focused on this subject, namely the International Association for Coastal Reservoir Research (IACRR).

I am happy to note that HYDROLINK - the magazine of the International Association for Hydro-Environment Engineering and Research (IAHR) is taking interest in coastal reservoirs and bringing out a special issue on this new topic and highlighting the need for such activities to help solvethe world's growing water crisis. On behalf of IACRR, I would like to thank IAHR, which is a worldwide independent organisation of engineers and water specialists working in fields related to hydro-environmental sciences and their practical application. I congratulate HYDROLlNK's editor and its committee members for taking this collaborative initiative through IACRR. I understand from Professor T G Sitharam, President of IACRR, that the Centre for Coastal Reservoir Research (CCRR) at the University of Wollongong conducted successfully the first International workshop on coastal reservoirs (CR) in collaboration with the International Association for Coastal Reservoir Research (IACRR) during Jan 24-25, 2018. I am pleased to note that this workshop had representation from water resources planners, politicians and water ministers from Australia and Malaysia, as well as researchers, engineers and scientists who spent time reviewing and assessing the feasibility of coastal reservoirs in securing universal and equitable access to safe and affordable drinking water. I am happy to note that the concept of storing water in downstream reservoirs (coastal reservoirs) is catching on and I understand that a number of major cities around the world are actively pursuing coastal reservoirs as a sustainable solution to their water problems. Coastal Reservoirsrepresentan innovative technology that can recover floodwater which otherwise would flow into the sea. I am also happy to hear that Hohai University will be hosting IACRR's 1st world congress on Coastal Reservoirs at Nanjing, China, in October 2020. I would like to congratulate Professor Sitharam from the Indian Institute of Science, Bangalore, and his team for taking the IACRR activities to new heights and I am pleased that IACRR is doing a great job to lead new beginnings in water management. I also congratulate the organizing committee of centre for coastal reservoir at University of Wollongong, NSW, Australia for successfully conducting the international workshop on coastal reservoirs. I am sure that IACRR can contribute to solving the water crisis of the major cities in the world and be the world's leading organization dedicated to advancing the art and science of coastal reservoirs by promoting thesustainable development of the world's flood water resources, now lost to the sea. I am confident that IACRR will certainly be a driving force dedicated to the growth, long-term success, and longevity of the human race and civilization. I wish all the very best tothe office bearers of IACRR and wish them a great success in embarking on a new vision. Thank you one and all.
