Abstract:The Indonesian Throughflow is made up of a series of ocean currents which flow from the tropical Western Pacific Ocean through the Indonesian Seas into the South Indian Ocean. The Leeuwin Current System, along the coast of Western Australia (22.1 o S?4.1 o S), forms a unique eastern boundary regime in which tropical waters flow poleward. The source waters of the Leeuwin Current are not well understood. Here we use the output generated by the numerical modelBluelink Reanalysis to analyze the characteristics of the large-scale oceanography of the Browse Basin and Bonaparte Basin, including the characteristics of the Indonesian Throughflow. The model shows that after emptying into the Indian Ocean, most of the Indonesian Throughflow (~ 7Sv) goes westward at 11篠- 13篠, sometimes in the form of eddies棏teddies? | |||

Abstract:The reference crop evapotranspiration of each typical hydrological years in Wuhan is calculated respectively by Priestley-Taylor formula, Hargreaves formula and Penman-Monteith formula. Based on the results of Penman-Monteith formula, the outcomes of Priestley-Taylor formula and Hargreaves formula are analyzed. It shows that there is no significant difference between the results of Hargreaves formula and Penman-Monteith formula. When the weather data required by Penman-Monteith formula was unavailable in this district, Hargreaves formula can be used to calculate ET0 instead of Penman-Monteith formula. There are many differences between the results of Priestley-Taylor formula and Penman-Monteith formula, Priestley-Taylor formula needs modified when used to calculate ET0 instead of Penman-Monteith formula in this district. | |||

Abstract:Numerical modelling is being used extensively to assist decision making in hydraulic and environmental field. TELEMAC System is a numerical modelling system for free surface hydrodynamics, water quality and sedimentology etc, popular in Europe but not introduced in China. The construction of 2D hydrodynamic model for Erhai Lake applies TELEMAC System for an interesting and important study. From the modeled results, lake hydrodynamics are well reproduced, the tracer’s behavior can also be seen. For the modelling itself, TELEMAC shows a good convenience and capability of reproducing reality. | |||

Abstract:Turbulent wakes past a circular cylinder are investigated by using both the numerical model and the digital Particle Image Velocimetry (PIV) technique. The fractional step finite element scheme is extended to simulate the turbulent wakes, it has good accuracy and stability properties, and is suitable for convection dominated flows in the wake region. The emphasize is put on simulating the unsteady vortex shedding processes and the saddle position, which are important for understanding the mechanism of the turbulent wakes. The time mean velocity properties are obtained, which show the recirculation region and the similarity characteristics are exist in the near region of the turbulent wakes. The numerical results are compared with the PIV measurements. | |||

Abstract:The entropy theory is introduced into dam safety evaluation in this paper. The generalized maximum entropy principle which can integrate various methods to determine weight is applied to obtain the weight of multi-index in dam safety evaluation. The method maximizes Shannon entropy of all random variables simultaneously to obtain relatively reliable and accurate results. A project example is given to prove this method feasible. Thus this paper provides a new idea to determine multi-index weight for similar projects. | |||

Abstract:Deep water high-pile wharf was constructed at outside sea, structure of inland needs high filling. The bulkhead will bear the soil pressure which produced by filling. Certain harbor was designed as structure-bulkhead structure of battle and sheet pile foundation, In view of that wharf was built on soft foundation, the structure system’s internal force will be quite complicated. This paper presents numerical simulation method to simulate high filling process, analyzes the structure’s deformation and mechanics, sums up some rules about this structure. The analysis and conclusions of this paper can be used as a reference for similar projects in future. | |||

Abstract:The Xin’anjiang model is used widely and perfected in China during the last thirty years, and WinBTOMC model is refers to the Blockwise application of TOPMODEL, which needs more high resolution hydrologic data and seems have a better performance. This study compared these two models on a same semi-arid basin, and the result is: the Xin’anjaing model performed much better than the WinBTOPMC model on yearly data while the WinBTOPMC model performs well on monthly metrological data. | |||

Abstract:To study the impact of the foundation structures of offshore wind energy plant on hydrodynamic conditions, a 2-D hydrodynamic numerical model was developed, including the Yangtze Estuary and the Hangzhou Bay. The results show that the influence is related with the characteristics of tidal current and the arrangement of foundation structures. As far as the Shanghai Offshore wind power stations are concerned, the impact on the tidal currents is limited in the region around the structures. | |||

Abstract:The magnitude of leakage loss of Beitang reservoir, Tianjin City, was determined; this was one of the objectives of the study. The Alyamani & Sen Equation, which is an empirical equation based on representative grain-size distribution parameters, was used in hydraulic conductivity, K, determination and Kriging method was applied to estimating the spatial variation of permeability of the reservoir bed. The results show that the average K values of the reservoir bottom sediment is 3.96×10-5 cm s-1, the leakage loss estimated by Darcy equation is 1375.87 m3 d-1, and the north central part of the reservoir displays higher risk of leakage loss. The results indicate that the method of determining K by using grain–size distribution analysis and Alyamani & Sen Equation is suitable for the area with the similar condition, and could provide some useful suggestions for the future work; especially when the traditional method were couldn’t used. | |||
