Roads and Floods: Best Practice Guidelines for the Integrated Planning and Design of Economically Sound and Environmentally Friendly Roads in the Mekong Floodplains of Cambodia and Viet Nam: Synthesis Report

This document presents a set of Best Practice Guidelines for road development and rehabilitation in the Mekong floodplains of Cambodia and Viet Nam. The guidelines are developed under the ‘Roads and Floods’ project1. The guidelines are based on the review of local practice, international experience, and case study results. They are intended for...

Bank erosion prediction and mitigation measures along the lower Mekong river

The Lower Mekong River area is a zone with plenty of natural resources and it has the highest agricultural production in Vietnam. The river passes though six provinces in the Southern patt of Vietnam, with more than 16 million in habitants in total. However, serious riverbank erosion problems occur and there is no master plan or mitigation...

A study on uncertainty in the design of river training works: And the development of a method and instruments to improve a full and consistent use of probabilistic design methods

The objective of this study is to make a study on dealing with uncertainty in the design of river training works. Based on this study, a method and several instruments have been developed that aim to improve a full and consistent use of a probabilistic design approach. This study is divided into three parts. The outline is rather unconventional...

Effect of changes in outer-delta bottom topographies on salt water intrusion

This study is about the effect of outer-delta bottom topographies adaptations on salt water intrusion in estuaries. An increase in salt water intrusion is considered as problematic in a lot of estuaries in the world. Various solutions are developed in the past to reduce salt water intrusion. These solutions have also negative side effects. An...

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...

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...
