This paper proposes and validates a new formulation on the dynamic response of dam-reservoir system, including water compressibility, absorption of the boundary of the reservoir, the earthquake excitation from different directions and the radiation condition boundary at infinity. The impounded water is modeled by Scaled Boundary Finite Element Method, and discretization only at the boundary coi...

—Eighty-three paddlefish Polyodon spathula that were collected from 1995 to 1999 from the Missouri River Galvins Point Dam tailwater were analyzed for genetic variation in the mitochondrial DNA d-loop region. Additional samples from Montana, South Dakota, and Louisiana were used for comparative purposes. To facilitate the efficient analysis of numerous paddlefish samples, we applied a method th...

Understanding the fish community structure and spatial distribution characteristics is essential for appropriate reservoir fishery management, especially in early impoundment stage of reservoir, which could help obtaining basic data performing artificial adjustments to biological communities. On basis this concept, we conducted a survey at newly constructed southwest China by using combination ...

Hydropower, as a flexible energy source, has sparked renewed interest in the ongoing decarbonisation of society. Simultaneously, wider transformation socio-ecological system towards more sustainable practices production is required. Our paper draws from theory and concepts transformability, hydro-social cycle, aquatic regime to study water governance regulation Finland. case data consists 16 se...

Abstract. A seasonal investigation of the occurrence of metacercariae in cyprinoid fish was conducted at the Kwae Noi Bamroongdan Dam, Phitsanulok Province, northern Thailand during December 2008-August 2009. A total 361 cyprinoid fish from 10 species were examined by artificial digestion method evaluating for metacercariae. The metacercariae determined were Haplorchis taichui, Haplorchis pumil...

Ground-based synthetic aperture radar (GBSAR) is a powerful tool used in monitoring structures, such as bridges and dams. However, despite the extremely short range of GBSAR interferometry, the atmosphere effects cannot be neglected. The permanent scatterer technique is an effective operational tool that utilizes a long series of SAR data and detects information with high accuracy. An algorithm...

Algal bioassay tests were conducted with Selenastrum capricornutum and natural algae on inner Las Vegas Bay, Lake Mead, Nevada, from December 1992 through September 1993, to identify any nutrient limitation in an area of the reservoir that has experienced problems associated with severe nutrient enrichment. Three areas were sampled based on a gradient of water quality conditions that existed in...

China's historiographical traditions tell of the successful control of a Great Flood leading to the establishment of the Xia dynasty and the beginning of civilization. However, the historicity of the flood and Xia remain controversial. Here, we reconstruct an earthquake-induced landslide dam outburst flood on the Yellow River about 1920 BCE that ranks as one of the largest freshwater floods of ...
