In many coastal and delta cities land subsidence exceeds absolute sea level rise up to a factor of ten. Without action, parts of Jakarta, Ho Chi Minh City, Bangkok and numerous other coastal cities will sink below sea level. Increased flooding and other widespread impacts of land subsidence result in damage totalling billions of dollars per year. A major cause of severe land subsidence is excessive groundwater extraction due to rapid urbanization and population growth. A major rethink is needed to deal with the ‘hidden’ but urgent threat of subsidence. Deltares presents a comprehensive approach to address land subsidence from the perspective of more sustainable and resilient urban development. Sinking cities - An integrated approach towards solutions In the framework of an integrated approach 10 key issues and possible solutions are presented below: Restriction of groundwater extraction . Natural and artificial recharge of aquifers. Development of alternative water supply (instead of groundwater) Integrated (urban) flood water management Improving governance and decision-making Decision support models and tools Appropriate monitoring and database system Integrating geotechnical aspects in planning and design of buildings and infrastructure Asset management, financing and public-private-partnerships (PPP) Exchange of knowledge and best practices

THE WATER SITUATION IS CRITICAL. TENDED TO BANGKOK THE CAPITAL OF THE COUNTRY. MAY HAVE TO SUFFER THE FATE THAT IS
DIFFERENT FROM NAKHON SAWAN AND THE. AYUTTHAYA THAT WAS A HUGE MASS OF WATER TO FLOW INTO THE FLOOD.
