Supplementary file: Dam-break flood calculation results and investigation data of the Ertan Hydropower Station We have conducted a detailed study on dam-break calculation of the Ertan Hydropower Station and compiled a report: Analysis report on dam-break flood of the Ertan Hydropower Station. This report contains eight chapters, 280 pages and all written in Chinese, it is difficult to translate all of them. Due to the flooding scenario is a full dam break in our study, we only translated the main content of full dam-break calculation process. 1. Basic equation The evolution of the flood wave downstream is calculated by Saint Venant equation, and the Saint Venant equation is: (1) Where: Q: Discharge at dam site (m3/s); A: Effective cross section area (m2); A0: Area of beach land (m2); x : Distance along the direction of water flow (m); t: Time (s); q: Lateral inflow or outflow (m3/s); g: Gravity (m/s2) n 2 Q Q f: S Friction ratio drop, S f 4 2.21A2 R 3 kQ / A2 Se:local head loss, S e 2gx h:Water elevation (m); k:Coefficient of contraction. 2. Computational method Presimann's four-point eccentric implicit scheme is used to solve the equations (1) and the values of h and Q can be obtained at any time. Implicit difference equation can be written as: j11 j j j QQQQ 1 j11 j j j i11 i10 i i AAAAAAAA 0i 0 i11 0 i 0 i xi x i 2 t j (2) j1 j1 1 Q 2 Q 2 Q j1 Q j1 Q j Q j 2t i i1 i i1 x A A j i i1 i 2 j 2 j j1 1 j1 j1 j1 j1 1 Q Q (3) g A hi1 hi S f Se x x A A i i i1 i j 1 j j j j g A hi1 hi S f Se 0 xi Where, A Ai Ai1 / 2 2 2 4 3 S f n Q Q 2.21A R Q Q Q 2 i i1 R A B B B B 2 i i1 3. -

Genetic Diversity in Population of Largemouth Bronze Gudgeon (Coreius Guichenoti Sauvage Et Dabry) from Yangtze River Determined by Microsatellite DNA Analysis
Genes Genet. Syst. (2010) 85, p. 351–357 Genetic diversity in population of largemouth bronze gudgeon (Coreius guichenoti Sauvage et Dabry) from Yangtze River determined by microsatellite DNA analysis Futie Zhang and Deqing Tan* Key Laboratory of Aquatic Biodiversity and Conservation of Chinese Academy of Sciences, Institute of Hydrobiology, Chinese Academy of Sciences, Wuhan 430072, China (Received 25 August 2010, accepted 23 November 2010) Largemouth bronze gudgeon (Coreius guichenoti Sauvage et Dabry 1874), one of the endemic fish species in the upper reaches of the Yangtze River in China, is a benthic and potamodromous fish that is typically found in rivers with torrential flow. Three dams in the Yangtze River, Ertan Dam, Three Gorges Dam and Gezhouba Dam, may have had vital impacts on the habitat and spawning behaviors of largemouth bronze gudgeon, and could ultimately threaten the survival of this fish. We studied the population genetic diversity of C. guichenoti samples col- lected at seven sites (JH, GLP, BX, HJ, MD, SDP and XB) within the Yangtze River and one of its tributaries, the Yalong River. Genetic diversity patterns were deter- mined by analyzing genetic data from 11 polymorphic microsatellite loci. A high genetic diversity among these largemouth bronze gudgeon populations was indi- cated by the number of microsatellite alleles (A) and the expected heterozygosity (HE). No significant population variation occurred among GLP, BX, HJ and MD populations, but dramatic population differentiation was observed among JH and XB, two dam-blocked populations, versus other populations. Tests for bottlenecks did not indicate recent dramatic population declines and concurrent losses of genetic diversity in any largemouth bronze gudgeon populations. -
Cracking Risk and Overall Stability Analysis of Xulong High Arch Dam: a Case Study

The three safety factors and five stress zones have a great significance for arch dam-foundation design of cracking control and overall stability evaluation. Abstract: It is of great significance to study the cracking risk, the overall stability, and the reinforcement measures of arch dams for ensuring long-term safety. In this study, the cracking types and factors of arch dams are summarized. By employing a nonlinear constitutive model relating to the yielding region, a fine three-dimensional finite element simulation of the Xulong arch dam is conducted. The results show that the dam cracking risk is localized around the outlets, the dam heel, and the left abutment. Five dam stress zones are proposed to analysis dam cracking state base of numerical results. It is recommended to use a shearing-resistance wall in the fault f57, replace the biotite enrichment zone with concrete and perform consolidation grouting or anchoring on the excavated exposed weak structural zone. -
