Temperature is one of the main loads super-high arch dams. (1) Background: a dam in southwest China was taken as an example this paper and temporal-spatial evolution law temperature analyzed based on monitoring data. (2) Methods: finite element simulation analysis method adopted to invert boundary conditions upstream surface thermal parameters concrete, process long-term operation simulated ana...

in semi arid area geomorphological impacts of dams are very major. dams, as man- made structures, have major impacts on river hydrology, primarly through in the timing, magnitude, and frequency of low and high flows, ultimately producing a hydrologic regime differing significantly from the pre-impoundment natural flow regime. despite the profiles of dams on river regulation for water resources ...

Impoundment of the Zipingpu reservoir (ZR), China, began in September 2005 and was followed 2.7 years later by the 2008 Mw 7.9 Wenchuan earthquake (WE) rupturing the Longmen Shan Fault (LSF), with its epicenter ~12 km away from the ZR. Based on the poroelastic theory, we employ three-dimensional finite element models to simulate the evolution of stress and pore pressure due to reservoir impound...

Hydrologic regime plays a major role in structuring biotic diversity within river ecosystems by controlling key habitat conditions within the river channel and floodplain. Daily flow records from seven hydrological stations and the range of variability approach were utilized to investigate the variability and spatial pattern of the hydrologic alterations induced by the construction of the Three...

Hydropower is often presented as a clean, reliable, and renewable energy source, but also recognized for its potential impacts on aquatic ecosystem biodiversity. We used direct empirical data of change in fish species richness following impoundment to develop ecological indicators be Life Cycle Assessment (LCA), accounting hydropower ecosystems. Data were collected 89 sampling stations (63 loca...

It is necessary to review changes in the interactions of indicators following construction Three Gorges Dam (TGD) order explore impact dam on ecology. Research among comprehensive social–economic–ecology system Yangtze River Basin limited, and objective this study was investigate how changed after operation TGD, as well contributed change. Here, correlational network approach using 38 data poin...
