Title: Great Changes on Flood Control of Lower Yellow River and Future Prospective (29 minutes)
The International Conference on Hydroscience & Engineering (ICHE) began in Washington DC in 1993. Beijing hosted ICHE in 1995, followed by Cottbus (1998), Seoul (2000), Warsaw (2002), Brisbane (2004), Philadelphia (2006), Nagoya (2008), Chennai (2010), Orlando (2012), Hamburg (2014) and Tainan (2016). This year ICHE 2018 was held in Chongqing on June 18-22, 2018.
The goal of this conference is to bring together researchers of academia and practitioners to share the latest scientific advancements, emerging technologies, and directions in issues relevant to Hydro-Engineering for Sustainable Development. This conference will provide opportunities to present novel research results and networking for future activities.
Abstract of my paper at ICHE 2018
The variations of flow and sediment caused by harnessing the upper and middle reaches of the Yellow River have changed the flood control situation in the lower reaches. The amount of flood and sediment entering into the lower reach has been gradually reduced significantly. The volume of sediment which is transported to the estuary has also been greatly reduced, so as the siltation and extension at the river mouth, thus its impact on the upper reaches can be ignored. After the operation of Xiaolangdi Reservoir, strong scouring was created on the downstream channel, so the capacity of flood discharge increased dramatically. The current downstream reach becomes one of the world's most secure rivers. Xiaolangdi Reservoir can play a greater role in the downstream river management, which will inevitably affect the future prospects of governing the Yellow River Basin. In order to prevent the situations due to excessive river management in North China, which can cause the environment of lower reaches of the Yellow River to deteriorate, we should maintain the healthy life of the Yellow River, and adjust the scale of governance projects on the upper and middle reaches.
