Mekong River Mekong Delta Map

Sedimentation techniques' target locations We examine the development of the present delta land elevation and determine if sedimentation techniques can maintain the surface elevation current with RSLR under a variety of future scenarios. We chose four sedimentation zones to demonstrate the possibilities for sediment control operations at various sizes and locations across the delta (Fig. 2). The sample regions illustrate a variety of sedimentation technique situations at a variety of scales, altitudes, and locations. Implementing the recommended solutions in various locations would take varying amounts of energy, since some would be gravity-driven while others would require mechanical intervention. Each scenario assumes that no sedimentation occurs outside of the targeted region in the remainder of the delta, which may be a reasonable assumption given the present low level of sedimentation.

The Mekong Delta in southern Vietnam is especially susceptible to global sea level rise, since it produces roughly half of the country's rice. Prolonged flooding and salt increases jeopardize the feasibility of three-season rice growing in this highly populated, low-lying area, which might impact up to 1 million people directly by 2050. 1 Significant Facts Sea level rise jeopardizes the feasibility of three-season rice production in southern Vietnam's Mekong River Delta. Since 1997, the delta has generated roughly half of the country's rice. 3

The Mekong Basin is not often thought of as a seismically active region, given a large portion of it is covered by a rather stable continental block. Nonetheless, portions of the basin in northern Laos, northern Thailand, Myanmar (Myanmar), and China are prone to earthquakes and tremors. These earthquakes seldom surpass a magnitude of 6.5 on the Richter scale and are thus unlikely to inflict substantial damage.

The Mekong River is Southeast Asia's longest river, stretching roughly 4,900 kilometers from its source in China's Tibetan Plateau to its mouth in the Mekong Delta of Vietnam. It drains six nations and has an area of 795,000 square kilometers. The Mekong River basin is characterized by a variety of drainage patterns, geography, and geomorphology, and is separated into upper and lower basins.
