The present study was carried out to determine the possible origins of sediments entering Taleghan Dam in northern part of Iran, in order to avoid further sedimentation and helping in extension of the useful life of the proposed dam. This was performed by XRD analysis. To do so, first of all, sediment sampling points were positioned along the Taleghan River. The collected samples, after coding,...

Abstract The sediment load in the Yangtze River downstream of Three Gorges Dam (TGD) has substantially declined recent decades. decrease is more profound below TGD, e.g., a 97% at Yichang, compared with that delta apex, 1200 km downstream, 75% decrease, implying along-river recovery. Two large river-connected lakes, i.e., Dongting and Poyang Lakes, may play role re-establishment river’s morphod...

Glacial Lake Missoula formed when the Purcell Trench lobe of the Cordilleran ice sheet dammed Clark Fork River in Montana during the Fraser Glaciation (marine oxygen isotope stage 2). Over a period of several thousand years, the lake repeatedly filled and drained through its ice dam, and floodwaters coursed across the landscape in eastern Washington. In this paper, we describe the stratigraphy ...

BACKGROUND The Three Gorges Dam (TGD) is a remarkable, far-reaching project in China. This study was conducted to assess the impact of TGD on changes in the ecological environment, snail distribution and schistosomiasis transmission in Dongting Lake area. METHODS Hydrological data were collected from 12 monitoring sites in Hunan section of Yangtze River before and after TGD was established. D...
