Book Synopsis Salinity and Tides in Alluvial Estuaries by : H.H.G. Savenije
Download or read book Salinity and Tides in Alluvial Estuaries written by H.H.G. Savenije and published by Elsevier. This book was released on 2006-01-26 with total page 208 pages. Available in PDF, EPUB and Kindle. Book excerpt: The book describes an integrated theory that links estuary shape to tidal hydraulics, tidal mixing and salt intrusion. The shape of an alluvial estuary is characterised by exponentially varying width and the absence of bottom slope. This topography is closely related to tidal parameters, hydraulic parameters and parameters that describe 1-dimensional mixing and salt intrusion. Starting from the fundamental equations for conservation of mass and momentum, analytical equations are derived that relate the topography to tidal parameters (tidal excursion, phase lag, tidal damping, tidal amplification), wave celerity, lateral and vertical mixing and salt intrusion. The book presents a review of the state of the art, a comprehensive theoretical background and ample case illustrations from all over the world. It provides tools with which human interference in estuary dynamics can be described and predicted, resulting from, for instance: upstream fresh water abstraction, dredging, climate change or sea-level rise. In describing the interactions between tide, topography, water quality and river discharge, it provides useful information for hydraulic engineers, morphologists, ecologists and people concerned with water quality in alluvial estuaries. Although the book can be used as a text book, it is mainly a monograph aimed at graduate students and researchers. * Provides new integrated theory for tidal hydraulics, tidal mixing and salt intrusion in alluvial estuaries * Presents a consistent set of analytical equations to compute tidal movement, tidal mixing and salt intrusion, derived from the fundamental laws of conservation of mass and momentum * Serves as a practical guide with many illustrations of applications in real estuaries
Book Synopsis Salt Intrusion, Tides and Mixing in Multi-Channel Estuaries by : Anh Duc Nguyen
Download or read book Salt Intrusion, Tides and Mixing in Multi-Channel Estuaries written by Anh Duc Nguyen and published by CRC Press. This book was released on 2008-11-01 with total page 174 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Book Synopsis Modelling Approaches to Understand Salinity Variations in a Highly Dynamic Tidal River by : Ali Dinar Abdullah
Download or read book Modelling Approaches to Understand Salinity Variations in a Highly Dynamic Tidal River written by Ali Dinar Abdullah and published by CRC Press. This book was released on 2017-03-16 with total page 181 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book reports the first systematic monitoring and modelling study on water availability, water quality and seawater intrusion of the Shatt al-Arab River (SAR) on the border of Iraq and Iran, where causes and concentration levels of salinity have not yet been fully understood, let alone addressed, leading to conflicting perceptions of its origin (external or internal), the natural conditions and the practices that can explain the current critical conditions. Current scientific knowledge on the SAR salinity problem is deficient, partially due to the complex and dynamic interaction between marine and terrestrial salinity sources, including return flows by water users of the different water sectors in the Euphrates and Tigris rivers upstream of the SAR. The development of a new series of monitoring stations and various modelling approaches helped to better understand the interactions between these different sources. The comprehensive and detailed dataset formed the basis for a validated analytical model that can predict the extent of seawater relative to other salinity sources in an estuary, and for a hydrodynamic model that can predict salinity changes. The adaptability of the models to changing conditions makes them directly applicable by water managers. The procedure can be applied to other comparable systems.
Book Synopsis Modeling morphodynamic evolution in alluvial estuaries by : Mick van der Wegen
Download or read book Modeling morphodynamic evolution in alluvial estuaries written by Mick van der Wegen and published by CRC Press. This book was released on 2010-12-30 with total page 188 pages. Available in PDF, EPUB and Kindle. Book excerpt: The main objective of this research is to investigate the governing processes and characteristics that drive morphodynamic evolution in alluvial estuaries by application of a process-based numerical model (Delft3D). It is of utmost importance to understand estuarine processes so that impact of human interference (like dredging and land reclamation) and long-term changes (like sea level rise) can be evaluated. The research addresses a number of cases ranging from an rectangular basins to real estuaries like the Western Scheldt in the Netherlands or San Pablo Bay in California. The more schematized approach allow to study morphodynamic evolution over several millennia under constant forcing and answers more fundamental questions related to conditions of equilibrium and related time scales. The more realistic cases give insight into the skill of the approach in predicting decadal morphodynamic developments. More processes are included to mimic realistic conditions and model results are compared to bathymetric measurements over the last century. The research shows that the modeling approach is good capable of describing stable morphodynamic calculations over a timescale of millennia with patterns similar to patterns observed in reality. Additionally, the approach shows that it is possible to predict decadal morphodynamic developments in real estuaries with significant skill.

The favourable reception and complimentary reviews accorded to all the volumes shows that the series is fulfilling a very real need. Volume 54 follows closely the objectives and style of the earlier volumes, continuing to regard the marine sciences—with all their various aspects—as a unity. Physical, chemical, and biological aspects of marine science are dealt with by experts actively engaged in these fields. The series is an essential reference text for researchers and students in all fields of marine science and related subjects, and it finds a place in libraries of universities, marine laboratories, research institutes and government departments. It is consistently among the highest ranking series in terms of impact factor in the marine biology category of the citation indices compiled by the Institute for Scientific Information/Web of Science.
Book Synopsis Wetlands: Ecosystem Services, Restoration and Wise Use by : Shuqing An
Download or read book Wetlands: Ecosystem Services, Restoration and Wise Use written by Shuqing An and published by Springer. This book was released on 2019-07-04 with total page 322 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume explores major wetland ecosystem services, such as climate cooling and water quality improvement, and discusses the recent wetland conservation and restoration activities in China and neighboring countries. The role of wetlands in either cooling or warming the climate is analyzed as the net balance between carbon sequestration and emissions of methane and nitrous oxide. Wetlands start off having a net warming effect on the climate but in time switch to net cooling. Further, they remove 40% of the N and P from run-off and groundwater flow in agricultural areas, but wetlands need to amount to 10% of the total catchment area to make a difference. Reflecting on the recent large investment in wetland ecological studies in China and neighboring countries, the book addresses invasive species in coastal wetlands as well as the protection and wise use of tidal flats around the Yellow Sea. It also presents promising regional case studies on wetland restoration. The book is intended for academics, students and practitioners in the field of wetland ecology, management and restoration, as well as consultants and professionals working in conservation, wise use and environmental policy.
Book Synopsis One-dimensional Analysis of Salinity Intrusion in Estuaries by : Arthur T. Ippen
Download or read book One-dimensional Analysis of Salinity Intrusion in Estuaries written by Arthur T. Ippen and published by . This book was released on 1961 with total page 130 pages. Available in PDF, EPUB and Kindle. Book excerpt: An experimental and analytical study of the basic factors which determine the instantaneous longitudinal distribution of salinity in a partially mixed estuary of constant section is presented. The mass-transfer equation is solved in two parts: (a) the quasi-steady-state convective-diffusion problem for an observer moving with the tidal velocity, and (b) the cyclic translation of saline water due to the tidal velocity. In the steady-state portion the apparent longitudinal diffusion coefficient is a function of the turbulence induced by the tide and of the internal circulations induced by the density difference. An expression is developed for the intrusion length as a function of the estuary length, mean depth, tidal amplitude and period, fresh-water discharge, ocean salinity, and estuary roughness. A stratification number is defined which expresses the degree of stratification or mixing in an estuary. (Author).

Available in PDF, EPUB and Kindle. Book excerpt: The book provides a comprehensive and up-to-date overview of the physical processes which, according to the present state of knowledge, determine the evolution of coastal systems and their response to human interventions. This response depends to a large degree on the self-organising properties of coastal dynamics, which form a leading theme throughout the book. The basic theoretical ideas are explained in text and figures and also in formulas for the more mathematically inclined reader. Theories are illustrated with examples from estuaries, coastal lagoons, beaches and tidal flat systems from all over the world. The rules and simple models can be used directly without relying on complex computations; much attention is given to the strengths and weaknesses of the underlying theories and their limits of applicability. The book is fully self-contained; some knowledge of basic physics and mathematics is recommended. The book is an upgrade of the first edition. Most parts are rewritten and chapters are added to incorporate research results, new insight and experience of the past ten years. This book is intended for everyone interested in coastal systems for professional or educational reasons.
