Abstract(4556) PDF(3529)
Abstract:
A coupled model integrating MODFLOW and TOPNET with the models interacting through the exchange of recharge and baseflow and river-aquifer interactions was developed and applied to the Big Darby Watershed in Ohio, USA. Calibration and validation results show that there is generally good agreement be...
Determination of minimum flood flow for regeneration of floodplain forest from inundated forest width-stage curve
Song-hao Shang, Xiao-min Mao
2010, 3(3): 257-268. doi: 10.3882/j.issn.1674-2370.2010.03.002
Abstract(3181) PDF(2239)
Abstract:
Flood is essential for the regeneration and growth of floodplain forests in arid and semiarid regions. However, river flow, especially the flood, had changed greatly with the increase of water diversion from rivers and/or reservoir regulation, which may result in severer deterioration of the floodpl...
Comparison of performance of statistical models in forecasting monthly streamflow of Kizil River, China

Abstract(3537) PDF(5179)
Abstract:
The purpose of the paper is to study the evolution mechanism of hydrochemical field and to promote unpredictable benefits to the living standards of local people and to the local economy in the southern plain area of Pengyang County, Ningxia, China. Based on the understanding of the hydrogeological ...
Analytical solution based on stream-aquifer interactions in partially penetrating streams
Yong Huang, Zhi-fang Zhou, Zhong-bo Yu
2010, 3(3): 292-303. doi: 10.3882/j.issn.1674-2370.2010.03.005
Abstract(2386) PDF(2600)
Abstract:
An analytical solution of drawdown caused by pumping is developed in an aquifer hydraulically connected to a finite-width stream on the condition of two streams. The proposed analytical solution modified Hunt’s analytical solution and not only considers the effect of stream width on drawdown, but al...
Application of artificial neural network to calculation of solitary wave run-up
You-xing WEI, Deng-ting WANG, Qing-jun LIU
2010, 3(3): 304-312. doi: 10.3882/j.issn.1674-2370.2010.03.006
Abstract(2397) PDF(2950)
Abstract:
The prediction of solitary wave run-ups has important practical significance in coastal and ocean engineering. But the precision of calculating is limited from the existing models. Artificial neural network technology has rapidly developed and been widely used in many fields. In this paper, a solita...
Numerical simulation of sediment deposition thickness at Beidaihe International Yacht Club
Cheng-gang LU, Zhou-hu WU, Guo-feng HE, Jie ZHU, Gui-yong XIAO
2010, 3(3): 313-320. doi: 10.3882/j.issn.1674-2370.2010.03.007
Abstract(2660) PDF(2622)
Abstract:
The finite element method (FEM) was used to simulate sediment hydrodynamics at the Beidaihe International Yacht Club, and a two-dimensional model was established. The sediment movement and deposition were analyzed under many tidal conditions in conjunction with the hydrological regime of the Daihe R...
Orifice plate cavitation mechanism and its influencing factors
Wan-zheng AI, Tian-ming DING
2010, 3(3): 321-330. doi: 10.3882/j.issn.1674-2370.2010.03.008
Abstract(3927) PDF(8050)
Abstract:
The orifice plate energy dissipater is an economic and highly efficient dissipater. However, there is a risk of cavitaion around the orifice plate flow. In order to provide references for engineering practice, we examined the cavitation mechanism around the orifice plate and its influencing factors ...
Energy efficiency in a water supply system: Energy consumption and CO2 emission
Helena M. RAMOS, Filipe Vieira, Didia I.C. Covas
2010, 3(3): 331-340. doi: 10.3882/j.issn.1674-2370.2010.03.009
Abstract(2772) PDF(3516)
Abstract:
This paper presents important fundaments associated to the water/energy consumption and enhances the importance of renewable energy sources. A model of multi-criterion optimization for energy efficiency based on water and environment management policy, the preservation of the water resources, the co...
Experiments and numerical simulations on transport of dissolved pollutants around spur dike
Li-ping CHEN, Jun-cheng JIANG
2010, 3(3): 341-353. doi: 10.3882/j.issn.1674-2370.2010.03.010

Abstract:
The flow field around spur dike is with three-dimension characteristic. To analysis the influences of the flow field on pollutant transport, based on compressive VOF scheme, the 3D transient compressive pollutant transport model CPTM and CE bounded differencing scheme were developed. For the calibra...
