Air-water transfer at wavy interfaces
Gas-water exchange is usually controlled by a thin surface layer in the liquid just beneath the interface. The structure and dynamics of the interface profoundly influence the rate of mass transfer. Of particular importance to environmental and climatical cycles is the large (3 to 5 fold) …

Thermal gradients and water transfer in unsaturated soil.
An investigation into the flux of soil water under the influence of a thermal gradient was conducted in closed soil systems in the laboratory. A thermal gradient was imposed across the sandy loam soil columns and measured continuously for the duration of the experiment. The movement of soil water …

Genetic analysis reveals bidirectional fish movement across the Continental Divide via an interbasin water transfer
Interbasin water transfers are becoming an increasingly common tool to satisfy municipal and agricultural water demand, but their impacts on the movement and gene flow of aquatic organisms are poorly understood. The Grand Ditch is an interbasin water transfer that diverts water from tributaries of …

Wetland Characteristics of Avian Cholera Outbreaks and Surface Water Transfer in the Nebraska Rainwater Basin Area
… has infected and killed thousands of migrating waterfowl each year since 1975 in Nebraska’s rainwater basin area. Disease outbreaks in migrating waterfowl populations just prior to the nesting season are of concern to biologists. Feedlots and itner-wetland basin surface water transfer mechanisms …

Water transfers in Northern California : analyzing the termination of the San Francisco--Modesto Irrigation District water transfer
… (SFPUC) attempted to broker a deal that would transfer water from the rural Central California district to the metropolitan Bay Area. With a contract length of 50 years, it represented the type of long--term agricultural--to--urban water deal many experts had long anticipated occurring in …

Some of the ecological effects of a small inter-basin water transfer on the receiving reaches of the upper Berg River, Western Cape
Inter-basin water transfer (IBT) is defined as the transfer of water from one geographically isolated river catchment, sub-catchment or river reach, to another. Thus, one river becomes a donor, and another the recipient. They are joined by a range of possible transfer routes. In many cases either …

Characterisation of surface water quality in the Luapula river basin and developing a WQImin model for potential inter-basin water transfer to the Kafue river basin.
This study underscored the importance of water quality, providing insights for sustainable resource management in decision-making and development planning. The study focused on the Luapula River Basin (LRB) in Zambia, a potential donor for inter-basin water transfers to the Kafue River Basin (KRB). …

A proposal for an improved institutional mechanism to facilitate interjurisdictional water transfers in Virginia
… in the resolution of interjurisdictional water transfer disputes in Virginia. Current interjurisdictional water transfers take place without the full compensation of all individuals and corporate entities that are damaged by the transfers. Water transfer projects remove land from the …

The importance of the ‘urban’ in agricultural-to-urban water transfers: Insights from comparative research in India and China
The task of reconciling competing water demands is made more complex by the urban transition occurring in many of the world’s river basins. As rising populations and economic development lead to the overexploitation of available water supplies, the largest water-using sector, agriculture, becomes …

The climatic significance of tropical forest edges and their representation in global climate models
… clearance of tropical humid forests influence water exchange between remnant forest patches and the atmosphere, and, if so, how this affects regional and global water exchange. Fieldwork presented in this thesis ascertains whether the amount of water transferred to the atmosphere from a humid …

The lateral load carrying capacity of wall ties used in cavity wall construction in the Western Cape : a comparison between the Butterfly-type wire tie and the Crimped-type wire tie
… Butterfly Tie and the Crimped lie as regards to water transfer, tensile and compression strengths based on the Australian Code [AS 2699-l 984] requirements as it is more comprehensive. The reason was because the Butterfly Tie has been promoted in cavity wall construction in South Africa for a …

Distribution of Maternal and Fetal Blood Flow within Cotyledons of the Sheep Placenta
… and fetal flow may be a sensitive determinant of water transfer, and the distribution of their ratio explains about 50% of the uterine—umbilical venous oxygen tension gradient. Analysis of the correlation between samples vs. the distance separating them suggested a weight of roughly 125 mg for …

Analysis of a Flat-Plate, Liquid-Desiccant, Dehumidifier and Regenerator
… model takes into account the desiccant, water and air flow streams. A parametric analysis was performed to evaluate the influence of some of the most important operational parameters on mass transfer performance, such as flow configuration, water mass flow rate and inlet temperature, and …

Water Allocation in Southern Alberta
This dissertation examines water allocation in southern Alberta and develops a fungibility framework for water rights and examines a range of characteristics impacting the transferability of water rights in southern Alberta. Fungibility is the degree to which water rights are homogenous. The …

Social impact assessment in a developing context : a case study of the upgrading of the Olushandja Dam, northern Namibia
… forms an important component of an international water transfer scheme. In the past, this reservoir has not been used to store water at its maximum capacity. An upgrading project has been proposed by the Namibian Department of Water Affairs (pWA).The project will entail significant fluctuations in …

Analysis of temporal and spatial changes in major dissolved salts in the Vaal River system over a 40 year period
… in salts composition and concentration in the water of the Vaal River and its catchment area over a 40-year period. From the data analysed, the graphs plotted, and the Maucha diagrams, the salinity of the Vaal River was majorly total alkalinity (TAL) and sulfate (SO4) dominated, with a …

Surface functionalisation techniques for colloidal inorganic nanocrystals
… In this thesis, new methods for the transfer of nanocrystals from organic to aqueous media are developed and the interaction of aqueous stabilised particles with serum proteins is investigated. In Chapter 3, a new method for the synthesis of a thin silica layer upon the surface of …
