2013, 6(3): 241-249. doi: 10.3882/j.issn.1674-2370.2013.03.001
Abstract(2368) PDF(3144)
Abstract:
The complexities of hydrological phenomena, the causes that lead to these complexities, and the essences and defects of reductionism are analyzed. The driving forces for the development of hydrology and the formation of branch subjects of hydrology are discussed. The theoretical basis and limitation...
Pollutant mixing and transport process via diverse transverse release positions in a multi-anabranch river with three braid bars
Zu-lin HUA, Wei JI, Ning-ning SHAN, Wei WU
2013, 6(3): 250-261. doi: 10.3882/j.issn.1674-2370.2013.03.002
Abstract(2086) PDF(2330)
Abstract:
A multi-anabranch river with three braid bars is a typical river pattern in nature, but no studies have been conducted to describe mixing characteristics of pollutants in the river. In this study, a physical model of a typical multi-anabranch river with three braid bars was established to explore th...
Characteristics of phosphorus adsorption by sediment mineral matrices with different particle sizes
Yang XIAO, Xiao-lian ZHU, Hao-ke CHENG, Kai-jie LI, Qi LU, Dong-fang LIANG
2013, 6(3): 262-271. doi: 10.3882/j.issn.1674-2370.2013.03.003
Abstract(2949) PDF(3342)
Abstract:
The particle size of sediment is one of the main factors that influence the phosphorus physical adsorption on sediment. In order to eliminate the effect of other components of sediment on the phosphorus physical adsorption, the sediment mineral matrices were obtained by removing inorganic matter, me...
Synthesis and characterization of carboxymethyl cellulose/organic montmorillonite nanocomposites and  its adsorption behavior for Congo Red dye
Min-min WANG, Li WANG
2013, 6(3): 272-282. doi: 10.3882/j.issn.1674-2370.2013.03.004
Abstract(2530) PDF(4472)
Abstract:
A series of carboxymethyl cellulose/organic montmorillonite (CMC/OMMT) nanocomposites with different weight ratios of carboxymethyl cellulose (CMC) to organic montmorillonite (OMMT) were synthesized under different conditions. The nanocomposites were characterized by the Fourier transform infrared (...
Variability in salt flux and water circulation in Ota River Estuary, Japan
Mohammad SOLTANIASL, Kiyosi KAWANISI, Junki YANO, Kazuhiko ISHIKAWA
2013, 6(3): 283-295. doi: 10.3882/j.issn.1674-2370.2013.03.005
Abstract(2010) PDF(2697)
Abstract:
In this study the sub-tidal and intra-tidal variations of salt fluxes in the upstream section of a shallow estuary (with a water depth of less than 3 m) were investigated. The salt fluxes were estimated based on the cross-sectional average salinity and velocity measured by the fluvial acoustic tomog...
Joint probability distribution of winds and waves from wave simulation of 20 years (1989-2008) in Bohai Bay
Xiao-chen YANG, Qing-he ZHANG
2013, 6(3): 296-307. doi: 10.3882/j.issn.1674-2370.2013.03.006
Abstract(2660) PDF(3703)
Abstract:
The joint probability distribution of wind speed and significant wave height in the Bohai Bay was investigated by comparing the Gumbel logistic model, the Gumbel-Hougaard (GH) copula function, and the Clayton copula function. Twenty years of wind data from 1989 to 2008 were collected from the Europe...
Optimized operation of cascade reservoirs on Wujiang River during 2009-2010 drought in southwest China
Xin SUI, Sai-nan WU, Wen-gen LIAO, Lan JIA, Tian-tian JIN, Xue ZHANG
2013, 6(3): 308-316. doi: 10.3882/j.issn.1674-2370.2013.03.007
Abstract(2031) PDF(2447)
Abstract:
The effects of optimized operation principles implemented at reservoirs on the Wujiang River in southwest China between September 2009 and April 2010 under drought conditions were analyzed based on operational data collected from the Guizhou Wujiang Hydropower Development Co., Ltd. A set of linear r...
Towards full predictions of temperature dynamics in McNary Dam forebay using OpenFOAM
Yu-Shi WANG, Marcela POLITANO, Ryan LAUGHERY
2013, 6(3): 317-330. doi: 10.3882/j.issn.1674-2370.2013.03.008
Abstract(2226) PDF(4178)
Abstract:
Hydroelectric facilities impact water temperature; low velocities in a reservoir increase residence time and enhance heat exchange in surface layers. In this study, an unsteady three-dimensional model was developed to predict the temperature dynamics in the McNary Dam forebay. The model is based on ...
 Application of modified k-ω model to predicting cavitating flow in centrifugal pump
Hou-lin LIU, Dong-xi LIU, Yong WANG, Xian-fang WU, Jian WANG
2013, 6(3): 331-339. doi: 10.3882/j.issn.1674-2370.2013.03.009
Abstract(2740) PDF(4877)
Abstract:
Considering the compressibility of the cavity in the cavitating flow, this paper presents a modified k-ω model for predicting the cavitating flow in a centrifugal pump, in which the modified k-ω model and Schnerr-Sauer cavitation model were combined with ANSYS CFX. To evaluate the modified and stand...
Impact of consolidation pressure on contaminant migration in clay liner
Zhi-hong ZHANG, Zhao-gang XU, Xiu-li DU, Hong-yan LI
2013, 6(3): 340-353. doi: 10.3882/j.issn.1674-2370.2013.03.010
Abstract(1900) PDF(2368)
Abstract:
Consolidation deformation occurs in clay liners under the self-weight of wastes at a simple garbage dump or dredged sediment dump, which leads to a decrease in the porosity. However, the migration of contaminants in clay liners is influenced by the porosity. Thus, the impact of consolidation deforma...
Effectiveness of inhibitors in increasing chloride threshold value for steel corrosion
Jin-xia XU, Lin-hua JIANG, Wei-lun WANG, Li TANG, Li CUI
2013, 6(3): 354-363. doi: 10.3882/j.issn.1674-2370.2013.03.011
