煤矿开采对自然保护区生态环境的影响（英文）

With the gradual attention of the state to the protection of natural ecological environment,the planning and layout of the nature reserve will overlap with some coal mine areas.In order to strengthen the construction of ecological civilization,it is necessary to study the impact of mining on the ecological environment of the nature reserve.Through the methods of GIS and RS,and evaluation of ecological protection index system,the differences and impacts of ecological environment changes before and after the planning of the nature reserve are analyzed.The results show that since 2002,the effect of water collection and artificial soil and water conservation measures on improving the ecological environment of vegetation are obvious,the dominant species of vegetation type in the overlapping area of coal mine and nature reserve have changed from grass vegetation to shrub vegetation,in which the area of arbor forest land has increased significantly,the vegetation coverage in the overlapping area has also increased considerably.The intensity of soil erosion has decreased year by year after mining the coal resources.Post-harvest hydraulic erosion intensity is mainly below mild,and the area of artificial soil and water conservation has increased significantly.The negative impact of the ground subsidence caused by coal mining on the ecological environment is less than the positive effect brought by artificial soil and water conservation measures,and it is generally developing in a more stable direction.The ecological protection status index increased from 32.98 to 45.94,and the change degree of ecological protection status in nature reserves is 12.9≥10.The ecological protection status of the nature reserve improved significantly.On the basis of ecological environment protection and restoration measures in the nature reserve,coal mines need to further study the comprehensive impact of human activities on the ecological environment of the nature reserve.     

The 9^th International Conference on Hydrodynamics （ICHD2010）

A NUMERICAL STUDY ON MECHANISM OF S-STARTS OF NORTHERN PIKE （ESOX LUCIUS）

Northern pike is regarded as a specialist in swimming acceleration. The force production mechanism of northern pike,Esox lucius,during its predation S-starts was numerically studied in this article. The problem was reasonably simplified to a loose-coupling problem of fish swimming dynamics and hydrodynamics just in the swimming direction. The approach involved the simulation of the flow by solving the two-dimensional unsteady incompressible Navier-Stokes equations and decribing the fish motion dynamics based on Newton’s Second Law. Visualizations of flow fields and vortex structures were performed. The results show that the large acceleration is obtained mainly in the first undulatory cycle in which the amplitude increases. In the second cycle,a couple of vortices are generated and induce a jet. In the third cycle,the jet is strengthened by the mergence of the vortices in the same direction. Through discussing the effects of various controllable factors on the swimming performance,it is found that the actual locomotion mode of the northern pike in nature is just the best choice.     

Modeling the formation of soluble microbial products （SMP） in drinking water biofiltration

Both a theoretical and an empirical model were developed for predicting the formation of soluble microbial products （SMP） during drinking water biofiltration. Four pilot-scale biofilters with ceramsite as the medium were fed with different acetate loadings for the determination of SMP formation. Using numerically simulated and measured parameters, the theoretical model was developed according to the substrate and biomass balance. The results of this model matched the measured data better for higher SMP formation but did not fit well when SMP formation was lower. In order to better simulate the reality and overcome the difficulties of measuring the kinetic parameters, a simpler empirical model was also developed. In this model, SMP formation was expressed as a function of fed organic loadings and the depth of the medium, and a much better fit was obtained.

Main Features of the SHP Sector in China——Hangzhou Regional Centre （Asia-Pacific） for Small Hydro Power （HRC）, Hangzhou, China.

1 An important sector in the hydropower industry Since the founding of the People‘s Republic of China in 1949, and particularly since the reform and opening up period, rural hydropower has witnessed swift development. Rural hydropower exploitation has been included in the plans for rural electrification development, and has become an important part of the water resources sector. A new SHP industryhas formed, combining social, economic and environmental benefits.     

LARGE EDDY SIMULATION （LES） OF TURBULENT FLOW BY FINITE DIFFERENCE METHOD

A Large Eddy Simulation (LES) technique was applied to solve the turbulent channel flow for Rer = 150.Three types of turbulence models are employed, such as the Smagorinsky model, the Dynamic Sub-Grid Scale(SGS) model and the Generalized Normal Stress (GNS) model. The simulated data in time series for the LES were averaged in both time and space to carry out the statistical analysis. Results of LES were compared with that of a DNS. As an application, a LES technique was used for 2D body in order to check the validation by investigating the turbulent vortical motion around the afterbody with a slant angle.     

Influence of emergent macrophyte （Phragmites australis） density on water turbulence and erosion of organic-rich sediment

The effects of the emergent macrophyte Phragmites australis on water turbulence, bottom shear velocity and water turbidity were experimentally studied with the stem densities 0 stems/m 2 -100 stems/m 2 and using organic-rich sediment. It is found that the maximum root-mean-square (rms) velocity and shear velocity decrease linearly with increasing stem density. By affecting the height of peak turbulence values, emergent plants can thus lower the frequency of sediment erosion events. Additionally, the slope of the rms turbulence increment decreases with increasing stem density. Thus, also the duration of strong turbulence is affected by the density of emergent macrophytes. The critical shear velocity for sediment resuspension is 0.0035 m/s-0.0055 m/s and not affected by the stem density. In the absence of macrophytes, water flow causes a 6.3-fold increment in turbidity, but with macrophytes turbidity values remain lower. The experiments suggest that even relatively low densities of Phragmites can have substantial effects on water turbulence and consequently on water quality.     

EFFECT OF ESCAPE DEVICE FOR SUBMERGED FLOATING TUNNEL （SFT） ON HYDRODYNAMIC LOADS APPLIED TO SFT

This paper presents a potential approach to settle the problem of surviving major safety accidents in Submerged Floating Tunnel (SFT) that detachable emergency escape devices are set up outside SFT. The Computational Fluid Dynamics (CFD) technology is used to investigate the effect of emergency escape devices on the hydrodynamic load acting on SFT in uniform and oscillatory flows and water waves by numerical test. The governing equations, i.e., the Reynolds-Averaged Navier-Stokes (RANS) equations and standard turbulence equations, are solved by the Finite Volume Method (FVM). Analytic solutions for the Airy wave are applied to set boundary conditions to generate water wave. The VOF method is used to trace the free surface. In uniform flow, hydrodynamic loads, applied to SFT with emergency escape device, reduce obviously. But, in oscillatory flow, it has little influence on hydrodynamic loads acting on SFT. Horizontal and vertical wave loads of SFT magnify to some extend due to emergency escape devices so that the influence of emergency escape devices on hydrodynamic loads of SFT should be taken into consideration when designed.

Strategic Measures and Incentive Policies of SHP in China——Hangzhou Regional Center（Asia-Pacific） for Small Hydro Power

At the primary stage of SHP development (1960s—1970s), wooden or iron-wooden turbines manufactured by agricultural machinery works were mainly adopted in China. Before 1949, SHP equipment was generally imported due to lack of domestic manufacturing capability. In 1952, the first turbine-generator unit of 800kW capacity was successfully made in China,
