— The evolution of Yangtze drainage system and the Three Gorges has aroused great interest for many years. In the " Three Gorges " , the Wu Gorge is formed by the Yangtze cuts through the Hengshixi Anticline, and the Wushan Mountain is the highest mountain in the " Three Gorges ". The Wu Gorge is also the shortest gorge, which also formed in the simplest geological background. So we choose Hengshixi anticline in our study in order to find out the fluvial and geomorphic evolution process of it. Isobase maps of second-third and third-fourth order streams and vertical dissection maps was made for two drainage of the Hengshixi anticline to reconstruct the former geomorphological surface of the area in order to understand the processes that are responsible of the genesis of the gorges in the area. The gorges were firstly identified and their morphometric parameters were analyzed. The results show that the former models that explain the genesis of those gorges (antecedence, superimposition, underground rivers top collapse) cannot be backed up by the evidence gathered. The gorges, as it appears on the data gathered, are the result of river piracy by headwater erosion in an asymmetric folds environment characterized by the development of strike stream, dip streams and antidip streams. The birth of the current Yangtze River by the piracy of the Chuanjiang and the Xiajiang were by such processes. The piracy disorganized the drainage system of the area, some beheaded rivers just formed lakes that by overflow are responsible of some later gorges the chronology of that river piracy is still need more studies.

The evolution of Yangtze drainage system and the Three Gorges has aroused great interest for many years. In the “Three Gorges”, the Wu Gorge is formed by the Yangtze cuts through the Hengshixi Anticline, and the Wushan Mountain is the highest mountain in the “Three Gorges”. The Wu Gorge is also the shortest gorge, which also formed in the simplest geological background. So we choose Hengshixi anticline in our study in order to find out the fluvial and geomorphic evolution process of it.

In order to improve the accuracy and rapidity of forecast of oil spill in Three Gorges Reservoir Area, and provide technical support for oil spill emergency decision-making. The paper designed an oil spill forecast model that can be used in Three Georges Reservoir Area by using EFDC model. Considering the effect of the wind and flow, and integrating with oil

Understanding the spatial and temporal variation of nutrient concentrations, loads, and their distribution from upstream tributaries is important for the management of large lakes and reservoirs. The Three Gorges Dam was built on the Yangtze River in China, the world's third longest river, and impounded the famous Three Gorges Reservoir (TGR). In this study, we analyzed total nitrogen (TN) concentrations and inflow data from 2003 till 2010 for the main upstream tributaries of the TGR that contribute about 82% of the TGR's total inflow. We used time series analysis for seasonal decomposition of TN concentrations and used non-parametric statistical tests (Kruskal-Walli H, Mann-Whitney U) as well as base flow segmentation to analyze significant spatial and temporal patterns of TN pollution input into the TGR. Our results show that TN concentrations had significant spatial heterogeneity across the study area (Tuo River> Yangtze River> Wu River> Min River> Jialing Riv...

To international observers of resistance against mega dams, the Chinese peasantry may seem rather passive. China builds dams. It builds lots of them. Time after time the Chinese Government seems to encounter little resistance. Perhaps the most infamous of these constructions is the Three Gorges Project (TGP) on the Yangtze River. It is the world’s largest dam and it was built with seemingly minimal resistance from those it directly affected. The dam was and remains high profile. This megalith of engineering graced the pages of National Geographic in the late 1990s and it captured the attention of the world’s media, non-governmental organizations (NGOs), and international banks. It also attracted criticism within China and abroad. The contention drew tourists from all over the world on long journeys to say goodbye to a place they did not know. However, for all the outside attention there was another group of people, a large group, who had to move to make way for the project. Some of them resisted and it is their resistance that this chapter explores.
