Book Description
This book contains the Proceedings of the Symposium on Perspectives in Southern Hemisphere Limnology which was held from 3-13 July 1984 in Wilderness, South Africa. It can be asked why this Symposium was necessary at a time when conferences, symposia and other gatherings of learned people abound. Limnologists in the Southern Hemisphere have for some time been pointing out that limnological theory and inland water management practices have been developed almost exclusively in Northern Hemisphere temperate latitudes. Most of the land masses of the Southern Hemisphere fall within lower latitudes, 0 from 20-40 S, where the climate tends to be dry, with low cloud cover and with high levels of incident radiation and high water temperatures. Wide extremes are experienced in both rainfall and runoff, which occur mainly in summer. Sedimentary geological structures give rise to dispersive soils and highly turbid waters. Physiological, behavioural or developmental adaptations in the floral and faunal components are necessary to cope with desiccation and low visibility.

Book Description
Limnology - the study of inland waters - had its genesis in Europe about the turn of the century. The studies of Fore1 on Lake Geneva were of seminal value at this time. It prospered under the early guidance of Thienemann, Naumann and Wesenberg-Lund in Europe and, soon transplanted, of Birge and Juday in North America (to name just a few early spirits). Now, liminology is a respectable scientific discipline taught at many universities, and limnologists are recognized as important contributors to our understanding of how this fragile spaceship functions. All this acknowledged, it must also be acknowledged that limnology is not yet a globally comprehensive science. To be sure, much is known about globally applicable processes, and the structural elements of aquatic ecosystems worldwide, but limnological emphases, interests and concerns remain essentially European and North American in balance. Much is known about lakes and rivers in less than one fifth of the world's land area (northern temperature regions); rather little is known about inland waters elsewhere.

Book Description
There are growing concerns about the decline of biodiversity due to human activities, such as infrastructure development and resource extraction. These activities, including coal mining and stream diversion, threaten ecosystems and wildlife significantly. Impact of Societal Development and Infrastructure on Biodiversity Decline is a book that examines these issues comprehensively. It provides insights into the complexities of biodiversity conservation amidst rapid societal development. This book is a timely solution for academics, researchers, and policymakers seeking to understand and mitigate the impacts of such activities on biodiversity. The book explores the ecological and biodiversity studies in coal mining areas through a detailed case studies in regions with major coal industries. It delves into the loss of biodiversity due to stream diversion, providing a thorough analysis of the ecological risks and costs involved. The book proposes mitigation measures to address these challenges, including impact assessments and an environmental management plan. Furthermore, it outlines a plantation program to restore biodiversity and ecosystem services, offering practical solutions for sustainable land use practices.

Book Description
Leading experts present methodologies for basinwide approaches to water quality restoration. In 15 chapters the identification of pollution sources, definition of standards and their attainability, surface and groundwater modeling, remediation of contaminated soils and sediments, development and implementation of low cost treatment technologies, basinwide water quality management and remediation, and economic and institutional issues are covered. The book focuses on the situation in central and eastern European countries; however, the topics and solutions are of general interest and have worldwide applications.

Book Description
These books are divided into two volumes. The first focuses on estuarine physics and physical processes and interpretations. I have, for the most parts, intentionally downplayed engineering applications to estuaries. It is my bias that a deeper understanding is accomplished with a physical approach, whereas an engineering approach is largely geared toward finding a solution to a problem. Of course, it is not always easy to make this distinction. The second volume is a presentation of physical case studies of several important estuaries, spanning the major geomorphic types. I believe that it can be very useful to all areas of the world. I have consciously strived to be more international to scope in selection of both authors and estuarine case studies.

Book Description
Inspection is crucial to the management of ageing infrastructure. Visual information on structures is regularly collected but very little work exists on its organised and quantitative analysis, even though image processing can significantly enhance these inspection processes and transfer real financial and safety benefits to the managers, owners and users. Additionally, new opportunities exist in the fast evolving sectors of wind and wave energy to add value to image-based inspection techniques. This book is a first for structural engineers and inspectors who wish to harness the full potential of cameras as an inspection tool. It is particularly directed to the inspection of offshore and marine structures and the application of image-based methods in underwater inspections. It outlines a set of best practice guidelines for obtaining imagery, then the fundamentals of image processing are covered along with several image processing techniques which can be used to assess multiple damage forms: crack detection, corrosion detection, and depth analysis of marine growth on offshore structures. The book provides benchmark performance measures for these techniques under various visibility conditions using an image repository which will help inspectors to envisage the effectiveness of the techniques when applied. MATLAB® scripts and access to the underwater image repository are included so readers can run these techniques themselves. Practising engineers and managers of infrastructure assets are guided in image processing based inspection. Researchers can use this book as a primer, and it also suits advanced graduate courses in infrastructure management or on applied image processing.

Book Description
Exchange of water, heat and other energy components between wetlands and the lower portion of the atmosphere is essential for functioning and development of these ecosystems, and for the decisions related to conservation or modification of wetlands. Transformation of the energy components by key parts of the ecosystem, such as water body and vegetated canopy, and complex exchange between the latter are often described in terms of energy fluxes. In this book, the diurnal and seasonal exchange of water, energy and heat storage is quantified, and compared across three wetland communities: reedgrass, bulrush, and open water. Total water loss is partitioned into surface evaporation and plant canopy transpiration, and examined in terms of main controlling variables. Actual, potential and equilibrium evapotranspiration rates are also examined in the framework of Penman-Monteith and McNaughton-Spriggs models, leading to an improvement in understanding the mechanisms of the water loss in wetlands. This study could be useful for professionals in Natural and Ecosystem Sciences, Hydrology, and in Natural Resources and Water Management.
