Flood Dynamics in the Vietnamese Mekong Delta available in PDF, EPUB and Kindle. Today, the Mekong Delta in the southern of Vietnam is home for 18 million people. The delta also accounts for more than half of the country's food production and 80% of the exported rice. Due to the low elevation, it is highly susceptible to the risk of fluvial and coastal flooding. Although extreme floods often result in excessive damages and economic losses, the annual flood pulse from the Mekong is vital to sustain agricultural cultivation and livelihoods of million delta inhabitants. Delta-wise risk management and adaptation strategies are required to mitigate the adverse impacts from extreme events while capitalising benefits from floods. However, a proper flood risk management has not been implemented in the VMD, because the quantification of flood damage is often overlooked and the risks are thus not quantified. So far, flood management has been exclusively focused on engineering measures, i.e. high- and low- dyke systems, aiming at flood-free or partial inundation control without any consideration of the actual risks or a cost-benefit analysis. Therefore, an analysis of future delta flood dynamics driven these stressors is valuable to facilitate the transition from sole hazard control towards a risk management approach, which is more cost-effective and also robust against future changes in risk.

Download and read online ebook Beautiful Floods write by Judith Ehlert. This book was released on 2012. Beautiful Floods available in PDF, EPUB and Kindle. Floods are generally perceived as natural hazards. This book, in contrast, portrays the 'beautiful floods' of the Mekong Delta, which annually constitute a substantial resource for people's rural livelihoods. With a focus on floods, the book employs a 'lifeworlds' analysis to investigate dynamics of environmental and livelihood knowledge among farming and fishing communities, and it demonstrates that rapid agrarian change has both positive and negative impacts.

Modeling of Hydrodynamics and Sediment Transport in the Mekong Delta available in PDF, EPUB and Kindle. This research aims to investigate the prevailing sediment dynamics and the sediment budget in the Mekong Delta by using a process-based model. Understanding sediment dynamics for the Mekong Delta requires high resolution analysis and detailed data, which is a challenge for managers and scientists. This study introduces such an approach and focuses on modeling the entire system with a process-based approach with Delft3D-4 and Delft3D Flexible Mesh (DFM). The first model is used to explore sediment dynamics at the coastal zone. The latter model allows straightforward coupling of 1D and 2D grids, making it suitable for analyzing the complex river and canal network of the Mekong Delta. The validated model suggests that the Mekong Delta receives ~99 Mt/year sediment from the Mekong River. This is much lower than the common estimate of 160 Mt/year. Only about 23% of the modelled total sediment load at Kratie is exported to the sea. The remaining portion is trapped in the rivers and floodplains of the Mekong Delta. The results advance understanding of sediment dynamics and sediment budget in the Mekong Delta. As such the model is an efficient tool to support delta management and planning.

Download and read online ebook The Mekong Delta System write by Fabrice G. Renaud. This book was released on 2012-06-01. The Mekong Delta System available in PDF, EPUB and Kindle. This book about the Mekong Delta presents a unique collection of state-of-the-art contributions by international experts from different scientific disciplines about the characteristics and pressing water-related challenges of the Mekong Delta in Vietnam. The Mekong Delta belongs to one of the areas, which are to expect the largest challenges concerning environmental change and climate change induced sea level rise . The Delta acts as the “rice bowl” of Southeast Asia and is home to over 17 Million people, who need to cope with ecologic as well as socio-economic changes linked to the rapid economic development of the country. Annual floods, severe droughts, salt water intrusion, degrading water quality, tropical cyclones, hydrologic changes due to hydropower projects in the upstream of the Mekong, coastal erosion, and the loss of biodiversity are some of the problems in the region. Heterogeneous resource management responsibilities, and the fact that the Mekong – and thus also the Delta – is influenced by six countries aggravate the situation. Integrated water resources management and fostered cooperation and information exchange are pressing needs for the sustainable development of the Delta.

The Mekong Delta of Vietnam is extremely vulnerable to floods and, therefore, the establishment of dike systems is generally considered an appropriate approach to flood control. Based on intensive field work in the heart of the Delta, this dissertation investigates current dike planning practices, as well as its implementation at district and commune levels. The research reveals numerous shortcomings with regard to planning and shows that the dike system also produces adverse negative impacts on the ecosystems and livelihoods. Dissertation.
