Research paper thumbnail of Three-Dimensional Velocity Distribution in Straight Smooth Channels Modeled by Modified Log-Law

Journal of Fluids Engineering, 2019

Time-average velocity distribution in steady and uniform channel flows is important for fundament... more Time-average velocity distribution in steady and uniform channel flows is important for fundamental research and practical application as it is always three-dimensional (3D), regardless of channel geometry. However, its determination has predominantly been carried out by using complex numerical software, even for the simplest geometry such as rectangular channels. The log-law was developed initially for circular pipe flows, where a single shear velocity is used to normalize the velocity (u+) and its distance (y+). Tracy and Lester found that the performance of the log-law can be extended to express velocity profiles in rectangular channels when the global shear velocities (gRS)0.5 and (ghS)0.5 are used to normalize the measured velocity u and its distance y. This study extends this discovery from the channel central line to the corner regions, and its general form of log-law was found to be valid even in trapezoidal or triangular open channels or closed ducts. This modified log-law ...

Currently, the total population is about 7 billion, and by 2050, global population is projected to be 9 billion. Additional 10 more Nile Rivers are needed, and the water demand is increasing steadily and significantly. On the other hand, more people are migrating toward coasts, the existing reservoirs’ capacity is continuously being reduced due to sedimentation by 1% annually; this has intensified the water deficit. In this paper, the water deficit is discussed, and a new technology of coastal reservoir and its successful application in Shanghai are presented, which can pump freshwater from the sea without desalination. The preliminary designs of coastal reservoirs in Malaysia, India/Bangladesh, and USA show that the coastal reservoir is a feasible and effective technology in the world for the water crisis for water supply and flood disaster mitigation.

Many proposals have been suggested to seal the water deficit up to 500GL/year in 2050. These countermeasures include more inland reservoirs, wastewater recycle and reuse, and desalination plants etc. this study shows that none of these measures are effective and sustainable for the problem, by analyzing the rainfall data (1200mm/year) and runoff data (10,000GL/year), it is found that the shortage is not water, rather than storage capacity. Based on this discovery, it is proposed that the technology of coastal reservoirs may be an alternative. Its feasibility and sustainability are discussed and analyzed in this paper in terms of water supply reliability and water quality. It is found that the strategy of coastal reservoirs meets the regional water demand well, and it is sustainable, environment-friendly and cost effective

Research paper thumbnail of Coastal Reservoirs - a Possible Strategy in Diversifying Water Supplies and its Case Study in Australia

In order to alleviate the global water stress, the conceptual strategy of coastal reservoir to harvest the stormwater has been proposed. Australia is the driest continent in the world on the whole, but a lot of the coastline is blessed with high annual rainfall, which leads to large amount of stormwater lost to the sea. Australian only manages to use 7.5% of its annual runoff, the lowest in the world. To diversify its water supply, it is suggested to harvest the stormwater using Coastal Reservoirs that are surrounded by seawater at the mouth of a river with sustainable river flow. This paper will discuss the feasibilities of coastal reservoirs to supply the 5 major cities: Sydney, Melbourne, Brisbane, Perth and Adelaide. The currently existing inland reservoirs of these cities are well below capacity throughout the whole country, it indicates the influence of climate change - further development of inland reservoirs may not be able to quench its thirsty. The potential problems of the proposed coastal reservoirs are identified, possible solutions are provided.

The appropriate definition of energy dissipation rate E in Bagnold's theorem is discussed and it is found that the sediment transport rate g, in unidirectional and bi-directional flows can be well predicted when E is defined as the product of bed shear stress T. and near bed velocity u. then the linear relationship between u. E and the sediment transport rate is examined using measured data. The good agreement between measured and predicted values indicates that the phenomena of sediment transport can be reasonably described by the near bed flow characteristics.

The main advantages of this formula are its ease of computation, accuracy in prediction, and the wide range of application. The total sediment discharge gt is computed directly and is linearly related to the new total load transport parameter, TT. The latter involves variables that can be easily measured in field conditions, i.e., flow depth, mean flow velocity, energy slope, median sediment size and density, and water temperature. The factor of proportionality k in the formula has been checked for a wide range of hydraulic conditions and it remains a constant equal to 12.5. Comparisons between the computed and measured total sediment discharge indicate that the predictions are good.

Research paper thumbnail of Simplified Model of Tractive-Force Distribution in Closed Conduits

Journal of Hydraulic Engineering, 2005

The model assumes that the surplus energy within any control volume in a three-dimensional flow will be transferred towards the nearest boundary to be dissipated. Based on this model, the flow cross sectional area in the closed duct is divided into subflow regions corresponding to the side walls and bed, and the shear distributions over the wetted perimeter within each subflow area are assessed. Analytical equations, valid for all channel aspect ratios, for the prediction of local and mean shear stresses along the bed and side walls in smooth rectangular duct flow are derived. The formulae give good predictions of the shear stress distributions when compared with existing experimental data in the literature. The possible applications of the model to nonrectangular duct flows are also discussed.

Research paper thumbnail of Strategy of water pollution prevention in Taihu Lake and its effects analysis

Journal of Great Lakes Research, 2010

Its waters are used by agriculture, industry and as major drinking water for several cities including Shanghai and Wuxi. The lake also is important for tourism, aquaculture and flood control. Taihu Lake and its surrounding areas are facing three major water-related threats: deteriorating water quality with inflow and runoff from its watershed; flooding during the rainy seasons; and water shortages during drier months. Noxious algae blooms are occurring with increasing frequency and water quality continues to decline. Remedial actions implemented to date have been ineffective. This paper proposes that the problems could be remedied by constructing a bypass channel (BPC), which would divert low-quality water from the lake during low precipitation periods and allow better quality water to flow into the lake during high flow periods. This remedial action would simultaneously deal with the deteriorating water quality of Lake Taihu and maintain its water level at a desired level. A preliminary assessment of this strategy shows that, if the BPC were implemented, the water quality of Taihu Lake would be improved significantly in few years, the flood disaster would be greatly mitigated, and the water shortage problem in the basin would be alleviated.

Most of previous researchers attributed the velocity deviation to the wave Reynolds stress-qũṽ only. However, this study shows that both the wave Reynolds stress and the momentum u v driven by secondary flow and/or non-uniformity are responsible to the velocity deviation from the log-law. The theoretical investigation starts from the Reynolds equations and uses the simplified mixing-length hypothesis. The theoretical equation which describes the interaction of velocity distribution and v in combined wave and current conditions from the bottom to the free surface is obtained, and the equation states that the non-zero wall-normal velocity v that has been ignored in previous studies also plays an important role as the wave Reynolds stress to the velocity profile. By comparing the model with the available experimental data, it is seen that the model predicted the essential features of the experimental results.

It is found that two of them are facing similar problems, such as water shortage, poor quality for water supply and decreasing runoff etc. Two basins suffer the sharp temporal and spatial variation in water resources, which results in flood threat and water stress alternatively. Consequently these two rivers have attracted global attention due to their significant impacts on their local economical development and ecological system. To alleviate the water stress conditions, this paper investigates the feasibility of coastal reservoirs at the river mouths to develop its runoff lost to the sea. The preliminary study shows that after the coastal reservoirs are built, the water supply in these two basins can be significantly increased and the water quality can be improved and the river runoff could be also increased. This is because (1) coastal reservoirs can retain the flood water in the sea without pollution from the seawater; (2) the contaminant concentration of floodwater is less than the river water in dry seasons; (3) the river flow can be increased if the water users drink from the coastal reservoirs.
