Outline of Final Research Achievements

Effects of natural and artificial impacts on a stability of sand bars in rivers were studied utilizing field survey data and laboratory experiments. The results show that artificial impacts such as dam construction and/or bank protection affect to some extent sand bar formation and its stability through changing not only sediment discharge but also its grain size constitution. In addition, flood frequency trend in recent years also changes both sediment yields and riverine vegetation growth/decay. This is deemed to cause extreme stabilization of sand bar, especially its bipolarization. The research outputs can be used as a fundamental information for developing a sediment control technique towards sustainable river environment restoration.
