With a sharp focus on environmental pollution and its impact on life and nature, scientists and engineers have studied the water treatment effect of natural wetlands for many years, resulting in the development of constructed wetlands (CWs) for treating wastewater. This informative new book provides current information and guidance on the construction, performance, operation, and maintenance of subsurface flow constructed wetlands of domestic and municipal wastewater.
The focus of the volume is to evaluate the performance of horizontal subsurface flow constructed wetlands in treating domestic wastewater to establish the limit that can be safely discharged to agricultural drains. Two-step procedures were used for the preparation of this book. Using modeling and statistical analyses of treated water samples showed a significant difference between different media for the treatment of most pollutants. The authors went on to design artificial neural network models (ANNs) using Matlab software to simulate some of the experimental data and to anticipate the parameters of output concentration.
The wetland systems have the ability to deal with various pollutants with different concentrations and to decrease the treated water to the standard limits. This volume presents the main role of emergent plants for treatment performance in the constructed wetlands and will be a very important resource for engineers in this field as well as for both undergraduate and graduate students.

Описание: This book describes how natural or constructed wetlands can be used to reduce pollution of freshwater and coastal ecosystems, while still preserving their biodiversity and ecological functions. Through a series of case histories described in 10 chapters in the monograph, the readers will gain an understanding of the opportunities, as well as the challenges associated with reducing point and non-point source pollution using natural, restored or constructed wetlands. The target audience will be water practitioners involved in projects utilizing integrated watershed management approaches to pollution abatement, as well as researchers who are designing projects focused on this topic.
Описание: This edited book presents the first collection of case studies and research projects on the sustainable technology of constructed wetlands for wastewater management under hot and arid climates. It is the first such work that summarizes in a single reference the current international experiences and knowledge on the implementation of this nature-based solution under these diverse and often harsh climatic conditions. It covers the relevant gap in the fragmented and limited literature by providing integrated information and documentation on the feasibility of this green technology. The book presents the treatment efficiency of constructed wetland facilities and the research output from 29 different countries across South America, Africa, Asia and Oceania, while it covers various applications such as domestic and municipal wastewater, various industrial effluents and municipal sludge. Many examples and case studies further demonstrate the potential of this technology to contribute to better address the issues of water scarcity and limited fresh water resources through circular management of treated effluents e.g. reuse in irrigation. It also discusses the various challenges and technical aspects that should be considered in such climates, along with the environmental, financial and social benefits of this technology. This work is a useful handbook and guide for professional engineers, practitioners, academics, researchers, students, and water authorities who wish to get a better understanding and first-hand information on the potential of constructed wetlands for cost-effective and sustainable wastewater management in countries with hot and arid climates.
Описание: This book identifies the key hydrologic and hydraulic factors which influence the performance of stormwater quality treatment systems such as constructed wetlands and bioretention basins. Mathematical relationships derived using conceptual models underpinned by fundamental hydraulic theory are presented to predict treatment performance. The key highlights of the book will include the identification of the linkages between influential hydrologic and hydraulic factors for constructed wetlands and bioretention basins to support more accurate prediction of treatment performance and effective design of these types of stormwater treatment systems. Furthermore, this book will showcase an innovative approach for using conceptual models to analyze stormwater treatment system performance.

Описание:
Constructed wetlands are proving to be the best natural treatment system for landfill leachates. Most of the contaminants in landfill leachates are degraded in treatment wetlands. Potential for long-term sustainability and significant cost savings are attractive features of this eco-technology. Documentation of the experience in this use of constructed wetlands has been limited. Constructed Wetlands for the Treatment of Landfill Leachates is the first compilation of the results of research from North America and Europe. Originally presented at an international symposium, this collection of papers offers the most recent research findings from the leading researchers in this new and innovative natural treatment system. Specific issues addressed in the text include:
leachate characteristics, and the potential for treatability by constructed wetlands
wetland treatment, processes and transformation
use of constructed wetlands in cold climatic conditions
assessment of the tolerance of wetland plants to the toxicity of leachates
role of plants in the treatments of leachates
integrated wetland systems
performance of different wetland treatment systems
cost comparisons of wetland technology vs. traditional treatment technologies The potential for environmental contamination due to leachates from landfills is increasing, and there is an urgent need to find ways and means to treat leachates in a sustainable way Constructed Wetlands for the Treatment of Landfill Leachates will provide an invaluable source of information on the subject for scientists, engineers, practitioners, policy makers, and regulatory officials.

Описание:
This monograph examines how higher education(HE) institutions construct ‘professional identities’ in the classroom, specifically how dominant discourses in institutions frame the social role, requisite skills and character required to practice a profession, and how students navigate these along their academic trajectories. This book is based on a longitudinal case study of a prestigious HE institution specialising in training professional interpreters.
Adopting an innovative research approach, it investigates a community of aspiring professionals in a HE context by drawing on small story narrative analysis from an ethnographic perspective to provide emic insights into the student community and the development of their social identities. The findings (contextualised by examining the curricula of similar institutions worldwide) suggest that interpreter institutions might not be providing students with a clear and comprehensive picture of the interpreter profession, and not responding to its increasingly complex role in today’s society.

Описание: This book presents a systematic attempt to generalize several fundamental physical laws related to subsurface fluid flow that are important for a number of contemporary applications in the areas of hydrogeology, reservoir engineering and rock mechanics. It also covers the history of discovering these physical laws, their respective scope of validity, and their generalizations or extensions. The physical laws discussed include Darcy’s law, Darcy-Buckingham law and Hooke’s law. Darcy’s law is the fundamental law for subsurface fluid flow. For low-permeability media, it is not always adequate because of the strong fluid–solid interaction. Though the Darcy-Buckingham law is often used for modeling subsurface multiphase flow, it is only valid under the local equilibrium condition. This condition does not hold in many cases, especially when fingering flow occurs. It is well known that subsurface fluid flow is coupled with mechanical deformation of subsurface media; in some applications, this coupling can play a dominant role. The continuum-scale elastic deformation of natural rock, however, does not always follow the traditional form of Hooke’s law.The book also presents applications of the proposed generalizations of the physical laws to several important engineering projects.
An integrated coverage of the subjects of surface, subsurface, and contaminant hydrology. The author presents the fundamental concepts of physical and contaminant hydrology of watersheds, rivers, lakes, soils, and aquifers in an easy and accessible manner to the environmental professional.
Prepares the reader to analyze today's environmental problems.
Many practical examples and solved problems illustrate the concepts. This edition includes clear presentation of concepts, consistent notation, 124 solved examples, 187 proposed problems, 152 illustrations, 71 tables, 46 short computer programs in MAPLE, answers to problems, extensive bibliography.
State of the art research on groundwater and contaminant transport modeling is explained in a clear fashion.
Recent research developments in nonlinear hydrologic science and simulation are included in this new edition.
New solutions of nonlinear infiltration are presented with simple numerical applications.
New developments in analytical decomposition are presented as simple and practical means to complex nonlinear hydrologic problems, such as regional groundwater flow modeling in homogeneous or heterogeneous media, regular or irregularly-shaped domains, steady or transient problems, multiple pumping wells, and nonlinear flow.
For contaminant transport, new applications to the simulation of nonlinear decay, nonlinear sorption, and unsaturated-saturated zones contaminant propagation are presented along with simple programs.
Описание: Arid and semi-arid regions can be defined as environments in which water is the limit- ing factor for bio-systems. Meeting the first demand, namely, supplying water to the agricultural communities and urban centers, involves, in many instances, the over-exploitation and misuse of nat- ural water resources.
