Climate change and trans-boundary development in the major deltas of world, including Vietnamese Mekong Delta have exacerbated environmental risks. Land subsidence, riverbed sand mining, intensive groundwater extraction all contributed to lower channel bed levels, resulting riverbank erosion loss assets livelihoods for local residents. This study investigated drivers, classified social vulnerab...
Abstract Despite being a simple and inexpensive pretreatment technology, the cost-effectiveness of riverbank filtration (RBF) depends on complex hydrogeological hydrogeochemical variables. One most important issues for decision makers regarding RBF is optimal site selection. Therefore, methodology multicriteria evaluation large-scale schemes offered. The primarily designed as prescreening metho...

Bank habitats provide important functions for riverine fish. Yet, they have been heavily modified by land use, technical flood protection measures, and hydropower installations. Fish species requiring specific to complete their life cycle strongly declined therefore become target of river restoration measures. This study compared abiotic conditions fish community composition three bank habitat ...
Riverbed material has multiple functions in river ecosystems, such as habitats, feeding grounds, spawning and shelters for aquatic organisms, particle size of riverbed reflects the tractive force channel flow. Therefore, regular surveys are conducted environmental protection flood control projects. The field method is most conventional survey. However, require much labor, time, cost to collect ...
