The book provides a critical evaluation of South Africa's freshwater resources to illustrate the way in which its freshwater resources, water access, services and infrastructure have continued to decline over the past three decades. The continued decline of water governance, management, water service delivery, dilapidated water infrastructure, dysfunctional local governments and overall excessive water degradation is illustrated and emphasized using real-life examples and case studies from various contexts within the country. The main argument of the book is that South Africa's freshwater resources have declined to such an extent that it can be described as a predicament. Questionable water governance decisions and reactive water management practices have led to no improvement and/or increased degradation of freshwater resources. An overall lack of service delivery exists across the country, in various contexts, leading to further water and social decline. An inter-disciplinary evaluation of South Africa's current water predicament is provided, major water crises are prioritized, and suitable recommendations are given to transform its predicament into problems which can be addressed. Suitable background information is given to emphasize the necessity of good water governance, management, and service delivery. South Africa's freshwater resources are evaluated with specific focus on the decline of informed water governance, management, service delivery and water quality. Factors requiring urgent attention are determined and suitable recommendations and/or actions are provided. An evaluation and overall synthesis focused on the transformation of the predicament into problems is provided. Primary water problems are prioritized according to urgency and suitable recommendations are given to assist in transforming the country's current complex water predicament into "simpler" water problems. Political will, collaboration with researchers, stakeholders, non-governmental organizations, and cooperation of civil society is required. South Africa's already scarce freshwater resources and decaying infrastructure will persist and possibly collapse if no major actions or interventions are implemented.

This textbook introduces step by step the basic numerical methods to solve the equations governing the motion of the atmosphere and ocean, and describes how to develop a set of corresponding instructions for the computer as part of a code. Today's computers are powerful enough to allow 7-day forecasts within hours, and modern teaching of the subject requires a combination of theoretical and computational approaches. The presentation is aimed at beginning graduate students intending to become forecasters or researchers, that is, users of existing models or model developers. However, model developers must be well versed in the underlying physics as well as in numerical methods. Thus, while some of the topics discussed in the modeling of the atmosphere and ocean are more advanced, the book ensures that the gap between those scientists who analyze results from model simulations and observations and those who work with the inner works of the model does not widen further. In this spirit, the course presents methods whereby important balance equations in oceanography and meteorology, namely the advection-diffusion equation and the shallow water equations on a rotating Earth, can be solved by numerical means with little prior knowledge. The numerical focus is on the finite-difference (FD) methods, and although more powerful methods exist, the simplicity of FD makes it ideal as a pedagogical introduction to the subject. The book also includes suitable exercises and computer problems.

The presence of concentrations of organic substances and cations in seawater is a matter of increasing concern to the water industry, environmentalists and the general public alike. It poses a threat of possible health hazards for humans, fish and crustacea. Until fairly recently, the analysis of seawater was limited to a number of major constituents such as chloride and alkalinity. Insufficient attention was given to the analysis of sediments. Analysis of Oceanic Waters and Sediments draws attention to the methods available for analysing sediments in seawater. It covers classical methods as well as the most advanced and recently introduced physical techniques. It also discusses the sensitivities and limitations of the methods. The book is comprised of two major components. The first is a review of the occurrence of organic compounds and cations as well as examples of pollution by these substances in the ocean. The second is concerned with determination of the concentrations of organic compounds and metals, including an in-depth examination of the most sensitive analytical methods that are available and necessary for detecting them due to their low concentrations in the ocean. A detailed exploration of the largely overlooked area of oceanic sediment analysis, this book is of high interest for all professionals in the water industry, from river management to fish industries, sewage effluent treatment and disposal, land drainage and water supply. Its scope also applies to agriculturalists, chemists, biologists, toxicologists, public health workers and public analysts.

This study describes the fundamentals of assessing the vulnerability of coral islands, as well as environmental management and resource exploitation. Using seabird subfossils, such as bones, guano, eggshells etc., which have been well preserved on the Xisha Islands in the South China Sea, the author identifies the influences of climate change and human activity on seabird populations and diets. Understanding the past is of great importance for predicting the future, and seabird subfossils provide valuable information, which can be used to study changes in seabird ecology, paleoceanography and palaeoclimate. Furthermore, this study proposes examining the biogeochemical cycling of some elements present in the geosphere, hydrosphere, biosphere and atmosphere.

A large part of the global population lives in arid lands which have low rainfall and often lack the water required for sustainable population and economic growth. This book presents a comprehensive description of the hydrogeology and hydrologic processes at work in arid lands. It describes the techniques that can be used to assess and manage the water resources of these areas with an emphasis on groundwater resources, including recent advances in hydrologic evaluation and the differences between how aquifer systems behave in arid lands versus more humid areas. Water management techniques are described and summarized to show how a more comprehensive approach to water management is required in these areas, including the need to be aware of cultural sensitivities and conditions unique to many arid regions. The integration of existing resources with the addition of new water sources, such as desalination of brackish water and seawater, along with reusing treated wastewater, will be required to meet future water supply needs. Also, changing climatic conditions will force water management systems to be more robust so that future water supply demands can be met as droughts become more intense and rainfall events become more intense. A range of water management techniques are described and discussed in order to illustrate the methods for integrating these measures within the context of arid lands conditions.

It is an integrated resource with theory and applications for those interested in hydrology, hydraulics and fluid mechanics. The self-contained book summaries the fundamentals for porous media and essential mathematics with extensive references supporting the development of the model and applications.

Sustainable technologies for water supply are urgently needed if water has to be supplied to billions of less fortunate people with inadequate access to water. These technologies must be simple, less expensive, less energy intensive, and easy to maintain for their adaptation among the poor masses. Four appropriate technologies are discussed here: solar pasteurization, membrane desalination, natural filtration (riverbank filtration), and solar distillation. Solar pasteurization can be a useful means of producing water at remote, but sunny locations where fuel may not be easily available for boiling water. Membrane desalination will remain as a viable means of drinking water production for individual households to large communities. Various membrane filtration techniques as well as the means to "democratize" membrane filtration have been presented. Riverbank filtration is a "natural" filtration technique where drinking water is produced by placing wells on the banks of rivers. The riverbed/bank material and the underlying aquifer act as natural filters to remove pollutants from river water. Solar distillation can be a viable method of drinking water production for individual households to small communities without the input of external energy. Sustainability framework and technology transfer are discussed through transdisciplinary analysis.

Excessive groundwater pumping, groundwater contamination, and subsurface thermal anomalies have occurred frequently in Asian coastal cities, greatly disturbing the urban aquifer and the subsurface environment. In this volume, the relationship between the stage of a city s development and subsurface environment issues have been explored. Intensive field surveys were done in Tokyo, Osaka, Seoul, Taipei, Bangkok, Jakarta, and Manila. New, advanced methods, including satellite, tracer techniques, and the social economy model, were developed to evaluate subsurface conditions. Groundwater storage and groundwater recharge rates, as well as the accumulation and transport of pollutants, have been compiled as integrated indices of natural capacities under climate and social changes, and used to evaluate the vulnerability risk for all cities. The indices have been made on a yearly basis for seven cities for a century (1900 2000). Using these indicators it is now possible to manage groundwater resources in a sustainable fashion. This volume is indispensable to researchers in hydrology, coastal oceanography, civil engineering, urban geography, social economy, climatology, geothermics, and urban management.
