An implicit wetting–drying algorithm for the discontinuous Galerkin method: Application to the Tonle Sap, Mekong River Basin

The accurate simulation of wetting–drying processes in floodplains and coastal zones is a challenge for hydrodynamic modelling, especially for long time simulations. Indeed, dedicated numerical procedures are generally time-consuming, instabilities can occur at the wet/dry front, rapid transition of wet/dry interface and mass conservation are...

Suspended sediment properties in the Lower Mekong River, from fluvial to estuarine environments

The Mekong river is one of the largest rivers in the world, which flows through six countries of Southeast Asia (China, Myanmar, Laos, Thailand, Cambodia and Vietnam). Its hydro-sedimentary regime is changing rapidly, as a consequence of a regional shift of land use (agriculture, road, etc.), damming, sand mining and climate changes, among...

Flood adaptive cities: Towards climate change adaption and urban development in the Mekong Delta

For three hundred years, Mekong delta has become a water society where inhabitants in this region developed adaptive strategies, often called “shaking hand with floods”. Historically, people first settled on the lightly higher terraces and later on the levees along the river. With the digging of canals, people started to settle along the canal...
