2 In China, there are more than 2,759 lakes with surface area greater than 1km , and 2 the total lake area is 91,019km . One-third of these lakes are freshwater lakes, and the majority are situated in the middle and lower reaches of the Changjiang River or in eastern China’s coastal areas. These lakes function as drinking water supplies, ood control systems, aquaculture and tourism resources, navigation channels, etc. Recently, many shallow lakes in China have been subject to rapid eutrophication and suffer from algal blooms. This issue has resulted in a shortage of drinking water and in degradation of their ecosystems. The control of eutrophication of shallow lakes is one of the main issues with which the local people and Chinese governments are concerned today. Lake Taihu is the third largest freshwater lake in China, with an area of about 2 2338km and a mean depth of 1. 9m, a typical shallow lake located in the delta of Changjiang River, the most industrialized and urbanized area in China. Its main function is supplying drinking water for the surrounding cities, such as Wuxi, Suzhou, and Shanghai, but tourism, aquaculture, sheries, and navigation are imp- tant as well. However, with economic development and increased population in the lake basin, Lake Taihu has suffered increasingly from serious eutrophication. The environmental issue of Lake Taihu is now a very common one, as most lakes from eastern China are confronted with it.

Thomas R Sinclair
R1,645 Discovery Miles 16 450 Ships in 18 - 22 working days

This volume explores specific approaches that have shown to result in crop yield increases. Research on the physiological understanding of these methods has led to the development of practical applications of plant breeding approaches to genetically improve crops to achieve higher yields. Authoritative entries from crop scientists shed new light on two water-conservation traits: one that is based on an initiation of the decrease in transpiration earlier in the soil drying cycle, and the second that is based on a sensitivity of transpiration rate under high atmospheric vapor pressure deficit that results in partial stomatal closure. Both these approaches involve partial stomatal closure under well-defined situations to decrease the rate of soil water loss. Readers will be able to analyze the circumstances under which a benefit is achieved as a result of the water-limitation trait; and key discussion points in the case studies presented will help answer questions such as what species, which environments, how often will yield be benefited for various crop species? Contributions also review the genetic variation for these two traits within each crop species and the physiological basis for the expression of these traits.

Broder J. Merkel; Edited by Darrell K. Nordstrom; Britta Planer-Friedrich
R1,974 Discovery Miles 19 740 Ships in 18 - 22 working days

To understand hydrochemistry and to analyze natural as well as man-made impacts on aquatic systems, hydrogeochemical models have been used since the 1960’s and more frequently in recent times. Numerical groundwater flow, transport, and geochemical models are important tools besides classical deterministic and analytical approaches. Solving complex linear or non-linear systems of equations, commonly with hundreds of unknown parameters, is a routine task for a PC. Modeling hydrogeochemical processes requires a detailed and accurate water analysis, as well as thermodynamic and kinetic data as input. Thermodynamic data, such as complex formation constants and solubility-products, are often provided as databases within the respective programs. However, the description of surface-controlled reactions (sorption, cation exchange, surface complexation) and kinetically controlled reactions requires additional input data. Unlike groundwater flow and transport models, thermodynamic models, in principal, do not need any calibration. However, considering surface-controlled or kinetically controlled reaction models might be subject to calibration. Typical problems for the application of geochemical models are: • speciation • determination of saturation indices • adjustment of equilibria/disequilibria for minerals or gases • mixing of different waters • modeling the effects of temperature • stoichiometric reactions (e.g. titration) • reactions with solids, fluids, and gaseous phases (in open and closed systems) • sorption (cation exchange, surface complexation) • inverse modeling • kinetically controlled reactions • reactive transport Hydrogeochemical models depend on the quality of the chemical analysis, the boundary conditions presumed by the program, theoretical concepts (e.g.

Abigail F. Cantor
R5,031 Discovery Miles 50 310 Ships in 10 - 15 working days

To keep drinking water safe involves more than following the letter of the law. This book introduces a comprehensive perspective and a proactive step-by-step approach to maintaining drinking water quality in distribution systems, and aids in delivering verifiably safe and economical water to end users. This second edition is updated throughout, and reflects the latest processes for improving drinking water quality in water systems and bringing those systems into compliance with the Lead and Copper Rule, the Disinfection By-Products Rule, and the Total Coliform Rule. It also presents the latest techniques for calming discolored water issues, keeping microbiological growth and biofilm formation in check, and preventing the formation of pinhole leaks in copper pipes. The book also aids in determining side effects of treatment chemicals, achieving simultaneous compliance with multiple regulations, and optimizing treatment chemical dosages. A typical water distribution system is complex and chaotic with varying piping configurations, water flows, chemical reactions, and microbiological activity. It is, therefore, no surprise that monitoring and assessing water quality can be a daunting task. Water Distribution System Monitoring: A Practical Approach for Evaluating Drinking Water Quality simplifies this task by providing the tools for well-defined and measurable control of water quality.

Dominic Stucker, Elena Lopez-Gunn
R1,612 Discovery Miles 16 120 Ships in 9 - 17 working days

The impacts of human-induced climate change are largely mediated by water, such as alterations in precipitation and glacial melt patterns, variations in river flow, increased occurrence of droughts and floods, and sea level rise in densely populated coastal areas. Such phenomena impact both urban and rural communities in developed, emerging, and developing countries. Taking a systems approach, this book analyzes evidence from 26 countries and identifies common barriers and bridges for local adaptation to climate change through water resources management. It includes a global set of case studies from places experiencing increased environmental and social pressure due to population growth, development and migration, including in Africa, Asia, Australia, Europe, North and South America. All chapters consider the crosscutting themes of adaptive capacity, equity, and sustainability. These point to resilient water allocation policies and practices that are capable of protecting social and environmental interests, whilst ensuring the efficient use of an often-scarce resource.

Uttam Roy, Mrinmoy Majumder
R1,408 Discovery Miles 14 080 Ships in 18 - 22 working days

The increase in GHG gases in the atmosphere due to expansions in industrial and vehicular concentration is attributed to warming of the climate world wide. The resultant change in climatic pattern can induce abnormalities in the hydrological cycle. As a result, the regular functionality of river watersheds will also be affected. This Brief highlights a new methodology to rank the watersheds in terms of its vulnerability to change in climate. This Brief introduces a Vulnerability Index which will be directly proportional to the climatic impacts of the watersheds. Analytical Hierarchy Process and Artificial Neural Networks are used in a cascading manner to develop the model for prediction of the vulnerability index.

Salt Intrusion, Tides and Mixing in Multi-Channel Estuaries - PhD: UNESCO-IHE Institute, Delft (Paperback): Anh Duc Nguyen Salt Intrusion, Tides and Mixing in Multi-Channel Estuaries - PhD: UNESCO-IHE Institute, Delft (Paperback)
Anh Duc Nguyen
R2,795 Discovery Miles 27 950 Ships in 10 - 15 working days

Multi-channel estuaries, such as the Mekong Delta in Vietnam and the Scheldt in the Netherlands, have characteristics of both the river and the sea, forming a unique environment influenced by tidal movements of the sea and freshwater flow of the river. This study addresses a number of knowledge gaps in multi-channel estuaries by developing a predictive analytical approach for salinity intrusion and discharge estimate in multi-channel estuaries. The new approach agrees well with 1-D hydrodynamic models and observations, indicating its applicability in practice. Most importantly, the study has successfully developed a new theory and a new equation to quantify tidal pumping due to ebb-flood channel residual circulation and the related salt dispersion.

Hans Eggenkamp
R3,208 Discovery Miles 32 080 Ships in 18 - 22 working days

This book provides detailed information on the history, analysis and applications of chlorine and bromine isotope geochemistry. Chlorine and bromine are geochemically unique as they prefer to exist as single charged negative ions. For this reason isotope fractionation reflects mostly processes that are not related to changes in the redox state and this fractionation is generally modest. The book will describe the processes that are most easily detected using these isotopes. Also isotope variations, and processes that cause them, measured in oxidised species such as perchlorates and in organic molecules will be described in this book.

Climate Driven Retreat of Mount Baker Glaciers and Changing Water Resources (Paperback, 1st ed. 2015): Mauri Pelto Climate Driven Retreat of Mount Baker Glaciers and Changing Water Resources (Paperback, 1st ed. 2015)
Mauri Pelto
R1,677 Discovery Miles 16 770 Ships in 18 - 22 working days

This book presents the impact of climate change on Mount Baker glaciers, USA, and the rivers surrounding them. Glaciers are natural reservoirs that yield their resource primarily on warm dry summer days when other sources are at their lowest yield. This natural tempering of drought conditions will be reduced as they retreat. Mount Baker, a volcano in the Cascades of Washington, is currently host to 12 principal glaciers with an area of 36.8 km2. The glaciers yield 125 million cubic meters of water each summer that is a resource for salmon, irrigation and hydropower to the Nooksack River and Baker River watersheds. Recent rapid retreat of all 22 glaciers is altering the runoff from the glaciers, impacting both the discharge and temperature of the Nooksack and Baker River. Over the last 30 years we have spent 270 nights camped on the mountain conducting 10,500 observations of snow depth and melt rate on Mount Baker. This data combined with observations of terminus change, area change and glacier runoff over the same 30 years allow an unusually comprehensive story to be told of the effects of climate change to Mount Baker Glaciers and the rivers that drain them.

Waterways and the Cultural Landscape (Hardcover): Francesco Vallerani, Francesco Visentin Waterways and the Cultural Landscape (Hardcover)
Francesco Vallerani, Francesco Visentin
R4,488 Discovery Miles 44 880 Ships in 10 - 15 working days

Water control and management have been fundamental to the building of human civilisation. In Europe, the regulation of major rivers, the digging of canals and the wetland reclamation schemes from the sixteenth to nineteenth centuries, generated new typologies of waterscapes with significant implications for the people who resided within them. This book explores the role of waterways as a form of heritage, culture and sense of place and the potential of this to underpin the development of cultural tourism. With a multidisciplinary approach across the social sciences and humanities, chapters explore how the control and management of water flows are among some of the most significant human activities to transform the natural environment. Based upon a wealth and breadth of European case studies, the book uncovers the complex relationships we have with waterways, the ways that they have been represented over recent centuries and the ways in which they continue to be redefined in different cultural contexts. Contributions recognise not only valuable assets of hydrology that are at the core of landscape management, but also more intangible aspects that matter to people, such as their familiarity, affecting what is understood as the fluvial sense of place. This highly original collection will be of interest to those working in cultural tourism, cultural geography, heritage studies, cultural history, landscape studies and leisure studies.

Water on Earth (Hardcover): C Lecuyer Water on Earth (Hardcover)
C Lecuyer
R3,768 Discovery Miles 37 680 Ships in 18 - 22 working days

The presence of water on Earth is discussed in this book using various theories about its origin as a basis. These theories include a massive degassing of the primitive parent bodies that built our planet as well as a late addition from comets that collided with the Earth s surface. The extraordinary physico-chemical properties of the water molecules, combined with its abundance and distribution over the Earth s surface, have contributed to regulating the global climate and favoring species evolution for more than 4 billion years. The early emergence of life in the deep ocean and its further diversification were closely linked to the global water cycle whose dynamics result from the energy balance between solar radiation and the internal heat flux of the Earth. Chapter 1 of this book deals with the extraordinary physico-chemical properties of the water molecule while Chapter 2 provides insight on theories regarding the origin of water on Earth. In the third chapter, the author focuses on the chemical composition of the main water reservoirs of our planet. Chapters 4 and 5 discuss water s relationship with plate tectonics and life, respectively. The sixth and final chapter uses stable isotope tracking to look into the water cycle and past climates. Contents 1. Water: A Molecule Endowed with Extraordinary Physicochemical Properties. 2. Theories about the Origin of Water on Earth. 3. The Main Water Reservoirs on Earth and their Chemical Composition. 4. Water and Plate Tectonics. 5. Water and Life. 6. Stable Isotope Tracking: Water Cycles and Climates of the Past.

R2,566 Discovery Miles 25 660 Ships in 10 - 15 working days

Methanol is an important volatile organic compound (VOC) present in the gaseous and liquid effluents of process industries such as pulp and paper, paint manufacturing and petroleum refineries. An estimated 65% of the total methanol emission was from the Kraft mills of the pulp and paper industries. The effect of selenate, sulfate and thiosulfate on methanol utilization for volatile fatty acids (VFA) production was individually examined in batch systems. Gas-phase methanol removal along with thiosulfate reduction was carried out for 123 d in an anoxic BTF. To examine the gas-phase methanol removal along with selenate reduction, another anoxic biotrickling filter (BTF) was operated for 89 d under step and continuous selenate feeding conditions. For the study on liquid-phase methanol, acetogenesis of foul condensate (FC) obtained from a chemical pulping industry was tested in three upflow anaerobic sludge blanket (UASB) reactors operated at 22, 37 and 55 C for 51 d. The recovery of VFA was explored through adsorption studies using anion exchange resins in batch systems. The adsorption capacity of individual VFA on Amberlite IRA-67 and Dowex optipore L-493 was examined by fitting the experimental data to adsorption isotherms and kinetic models. A sequential batch process was tested to achieve selective separation of acetic acid from the VFA mixture.

R2,756 Discovery Miles 27 560 Ships in 10 - 15 working days

This book highlights the likely impacts of climate change in terms of global and national water securities, how different countries are attempting to address these complex problems and to what extent they are likely to succeed. A major global concern at present, especially after the social and economic havoc that has been caused by COVID-19 in only one year, is how we can return to earlier levels of economic development patterns and then further improve the process so that sustainable development goals are reached to the extent possible by 2030, in both developed and developing countries. Mankind is now facing two existential problems over the next several decades. These are climate change and whether the world will have access to enough water to meet all its food, energy, environment and health needs. Much of expected climate change impacts can be seen through the lens of extreme hydrological events, like droughts, floods and other extreme hydrometeorological events.

Rethinking Faecal Sludge Management in Emergency Settings - Decision Support Tools and Smart Technology Applications for... Rethinking Faecal Sludge Management in Emergency Settings - Decision Support Tools and Smart Technology Applications for Emergency Sanitation (Paperback)
Fiona Zakaria
R2,566 Discovery Miles 25 660 Ships in 10 - 15 working days

The development of technology in the emergency sanitation sector has not been emphasised sufficiently considering that the management of human excreta is a basic requirement for every person. The lack of technology tailored to emergency situations complicates efforts to cater for sanitation needs in challenging humanitarian crisis. Concerns persists on the lack of faecal sludge management that considers the whole sanitation chain from containment until treatment. This study focused on the development of a smart emergency toilet termed the eSOS (emergency sanitation operation system) smart toilet to address the limitation in technical options. This toilet is based on the eSOS concept that takes into account the entire sanitation chain. This study also addresses the limited time for planning in emergencies by developing a decision support system (DSS) to help quick selection of optimal sanitation options. The aim was to enable users of the DSS to plan their emergency sanitation response within the shortest time possible. The study aims to contribute toward a better emergency sanitation response by application of technology advances.
