This book was released on 1995 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Researchers have found that hydrology and the dynamic nature of water flowing through wetlands affects the vegetation (composition, structure, and diversity), influences its primary productivity, controls its organic accumulation, and drives its nutrient cycling (Gosselink and Turner 1978).

Book excerpt: This Technical Note identifies future research needs for improving the predictive capability of the Wetlands Dynamic Water Budget Model (WDWBM) for computer simulations of wetland hydrology and hydraulics. The WDWBM was based on a number of models in common use and incorporates many of these models' theories and approaches. An underlying objective was to keep the model relatively simple and efficient, so that it could simulate year-to-year variations. While many of the future model modifications will arise from applications, several areas of study have been identified to improve model accuracy, efficiency, and reliability. The current version of the vertical processes module uses a Priestley-Taylor (1972) description of evapotranspiration. This procedure only requires knowledge of air temperature and net solar radiation. More sophisticated methods for estimating evapotranspiration could be examined to assess their effectiveness and data requirements. The vertical processes module assumes a saturated flow condition for infiltration across the ground surface. A more exact physical description of unsaturated infiltration could be incorporated into the model. A number of methods can be used to determine hydraulic conductivity when simulating groundwater flow. It would be useful to examine the effects of these methods on model results. It also would be useful to examine the potential computation savings and effects on model accuracy of using an implicit algorithm for at least the vertical processes module. In addition to describing potential model improvements and future applications, the note presents guidelines for using the water budget model as a test platform for the development and verification of simplified methods of wetland hydrology and hydraulics analyses. A simplified method is described for determining stage and hydroperiod throughout the Black Swamp area of the Cache River in Arkansas.

Download or read book Constructed Subsurface Wetlands written by Abdel Razik Ahmed Zidan and published by CRC Press. This book was released on 2018-01-03 with total page 650 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book Scale Issues in Hydrological Modelling written by J. D. Kalma and published by John Wiley & Sons. This book was released on 1995-09-11 with total page 518 pages. Available in PDF, EPUB and Kindle. Book excerpt: There is a growing need for appropriate models which address the management of land and water resources and ecosystems at large space and time scales. Theories of non-linear hydrological processes must be extrapolated to large-scale, three-dimensional natural systems such as drainage basins, flood plains and wetlands. This book reports on recent progress in research on scale issues in hydrological modelling. It brings together 27 papers from two special issues of the journal Hydrological Processes. The book makes a significant contribution towards developing research strategies for linking model parameterisations across a range of temporal and spatial scales. The papers selected for this book reflect the tremendous advances which have been made in research into scale issues in hydrological modelling during the last ten years.

Available in PDF, EPUB and Kindle. Book excerpt: Both practical and theoretical, this book provides the basic principles of soil chemistry, hydrology, wetland ecology, microbiology, vegetation and wildlife as a sound introduction to this innovative technology to treat toxic wastewaters and sludges. The use of wetlands for acid mine drainage, and metals removal in municipal, urban runoff, and industrial systems is discussed. Case histories are also presented, demonstrating specific types of constructed wetlands and applications to municipal wastewater, home sites, coal and non-coal mining, coal-fired electric power plants, chemical and pulp industry, agriculture, landfill leachate, and urban stormwater. Construction and management guidelines are clearly explained, providing information on applicable policies and regulations, siting and construction, and operations and monitoring of constructed wetlands treatment systems. Recent theoretical and empirical results from operating systems and research facilities, including such new applications as nutrient removal from eutrophic lakes and urban stormwater treatment within highway rights-of-way, are included.

Download or read book Wetland Techniques written by James T. Anderson and published by Springer Science & Business Media. This book was released on 2013-10-10 with total page 469 pages. Available in PDF, EPUB and Kindle. Book excerpt: Wetlands serve many important functions and provide numerous ecological services such as clean water, wildlife habitat, nutrient reduction, and flood control. Wetland science is a relatively young discipline but is a rapidly growing field due to an enhanced understanding of the importance of wetlands and the numerous laws and policies that have been developed to protect these areas. This growth is demonstrated by the creation and growth of the Society of Wetland Scientists which was formed in 1980 and now has a membership of 3,500 people. It is also illustrated by the existence of 2 journals (Wetlands and Wetlands Ecology and Management) devoted entirely to wetlands. To date there has been no practical, comprehensive techniques book centered on wetlands, and written for wetland researchers, students, and managers. This techniques book aims to fill that gap. It is designed to provide an overview of the various methods that have been used or developed by researchers and practitioners to study, monitor, manage, or create wetlands. Including many methods usually found only in the peer-reviewed or gray literature, this 3-volume set fills a major niche for all professionals dealing with wetlands.
