The whole book is composed by four parts, Part A is flood risk management in Yellow River Delta, Part B is flood risk management in Rhine River Delta, Part C is flood risk management in Mississippi River Delta, each part includes the problems, problem analysis and possible solutions,and Part D is comparisons and recommendations. The problems existing in each delta are similar in some extent or in a certain scope. The common problems are high flood from the river, storm surge (hurricane) from sea, land subsidence and land loss, coastal erosion, sea level rise, etc.. In each delta area, there are common or special reasons for different problems and traditional or peculiar measures are carried out in problem addressing. These measures are very valuable for each other,and could be learned from their experience and lessons.

The book is composed by four parts: Part A is flood risk management in Yellow River Delta, Part B is flood risk management in Rhine River Delta, and Part C is flood risk management in Mississippi River Delta, and each part includes the problems, analysis and possible solutions, and Part D is comparisons and recommendations. The objective of the book is focused on the flood risk management in these three deltas, and a comparison is made on several aspects: physical, socio-economical, technical, organizational and institutional, legal and policy. We hope the information, the analysis in flood risk management for each delta is helpful to understand the current situation andfuture problems in flood and improve the protection of local people' s lives and property and the soeio-economie development.
