Abstract
During last 15 years, the Red River in northern VietNam has experienced severe river beddegradation along its lower course. The continued decrease of the minimum water levels aggravated water scarcity for agriculture. These outcomes can be attributed to strong in stream sediment mining, major upstream impoundments, climatic and land use changes. The aim of this work is to provide a valuable tool to assess the effects of different reservoir water releases and sediment mining policies on river reach morphology. A 1D mobile bed finite volume numerical model has been set up and preliminary results on the recent 2000-2009 period are presented and discussed. The model features facilitate its integration in optimizationalgorithms devoted to water management strategies.I documenti in SFERA sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
