Download or read book Environmental Flow Assessment written by John G. Williams and published by John Wiley & Sons. This book was released on 2019-03-26 with total page 240 pages. Available in PDF, EPUB and Kindle. Book excerpt: Provides critiques of current practices for environmental flow assessment and shows how they can be improved, using case studies. In Environmental Flow Assessment: Methods and Applications, four leading experts critique methods used to manage flows in regulated streams and rivers to balance environmental (instream) and out-of-stream uses of water. Intended for managers as well as practitioners, the book dissects the shortcomings of commonly used approaches, and offers practical advice for selecting and implementing better ones. The authors argue that methods for environmental flow assessment (EFA) can be defensible as well as practicable only if they squarely address uncertainty, and provide guidance for doing so. Introductory chapters describe the scientific and social reasons that EFA is hard, and provide a brief history. Because management of regulated streams starts with understanding freshwater ecosystems, Environmental Flow Assessment: Methods and Applications includes chapters on flow and organisms in streams. The following chapters assess standard and emerging methods, how they should be tested, and how they should (or should not) be applied. The book concludes with practical recommendations for implementing environmental flow assessment. Describes historical and recent trends in environmental flow assessment Directly addresses practical difficulties with applying a scientifically informed approach in contentious circumstances Serves as an effective introduction to the relevant literature, with many references to articles in related scientific fields Pays close attention to statistical issues such as sampling, estimation of statistical uncertainty, and model selection Includes recommendations for methods and approaches Examines how methods have been tested in the past and shows how they should be tested today and in the future Environmental Flow Assessment: Methods and Applications is an excellent book for biologists and specialists in allied fields such as engineering, ecology, fluvial geomorphology, environmental planning, landscape architecture, along with river managers and decision makers.

This book was released on 2003 with total page 144 pages. Available in PDF, EPUB and Kindle. Book excerpt: An environmental flow is the water regime provided within a river, wetland or coastal zone to maintain ecosystems and their benefits where there are competing water uses and where flows are regulated. Pioneering efforts in South Africa, Australia and the United States have shown that the process to establish them poses great challenges. Second in the series of the Water & Nature Initiative, this guide draws extensively on the experiences in these countries to offer hands-on advice and practical guidance on technical issues for this emerging issue on the water resource agenda.

Available in PDF, EPUB and Kindle. Book excerpt: Environmental flows dynamically change the solid earth, form a key part of various ecosystems, and deeply shape our society. Pursuing sustainability requires advancing our understanding of various environmental flow systems, because they are associated with resources, environmental health, and natural hazards. However, establishing a comprehensive understanding of these systems is usually challenging because of the complexity of earth systems and the difficulty in directly observing the dynamically evolving flows. Numerical modeling have been an important approach in studying environmental flows, because it can both patch together available data to form a consistent picture of unobservable processes and decode the information in observations to help improving our interpretation of the valuable data. In this dissertation we present model frameworks that bridge numerical models with data for two types of environmental flows, magmatic flow in volcanic systems and pollution of surface water. The motivation of focusing on these two systems is to provide insights for tackling challenges in natural hazard and environmental enforcement. In Chapter 1, we introduce the context and challenges of studying environmental flows and provide an overview of each chapter. In Chapter 2, we present a model framework for quantifying the magma mixing in the conduit flow of persistently degassing volcanoes. This model framework consists of a conduit-flow model that simulates the dynamics of bubble-bearing magma in volcanic conduits, and a volatile-concentration model that bridges magma mixing with melt and gas composition. By quantifying how different rates of magma mixing in conduit flow alters the volatile concentrations of melt at depth and the compositions of volcanic gas, this study demonstrates that the observed compositions of melt inclusion and surface gas flux support the bidirectional conduit flow in persistently degassing volcanoes. In Chapter 3, we investigate the formation mechanism of quartz-hosted embayments and melt inclusions during the crystallization of silicic magma using direct numerical simulations. By integrating crystal growth, the evolution of water concentrations, and the flow of surrounding melt, this chapter proposes a formation mechanism of embayments and melt inclusions and provides new insights for interpreting their compositions. We find that water is more enriched in the interior of defects on crystal surface compared to the exterior because the removal of water from the interior is less efficient. The resultant lower disequilibrium in the defect interior causes lower growth rate than in the exterior, elongating the defect into an embayment. The melt entrapped by both embayments and melt inclusions may be enriched in incompatible components, such as water and carbon dioxide. The degree of enrichment depends on inclusion size, component abundance, the crystal growth regime, and the post-formation equilibration with surrounding melt. In Chapter 4, we propose a model framework for attributing agricultural phosphorus pollution in a river network at high spatiotemporal resolutions and to specific source types. This model framework consists of a forward model of nutrient transport and an inverse model with statistical inferences. We construct the prior distributions of source contributions by integrating data of nutrient input, nutrient uptake, and land use. We develop the nutrient transport model based on the river network and stream flow data. With the water-quality data, we update the prior distribution using the Approximate Bayesian Computation method to generate the posterior distributions of source contributions. Our attribution results reveal significant variability in subwatershed-scale phosphorus release. Phosphorus release is higher during spring planting than the growing period, with fertilizer contributing more SRP than manure and manure contributing most of the UP. The results also suggest locations for additional water-quality monitors by identifying regions with high contributions but ambiguous attribution results due to the lack of water-quality measurements and disagreements between existing datasets of nutrient input.

Download or read book Water Environment Modeling written by Clark C.K. Liu and published by CRC Press. This book was released on 2021-11-01 with total page 335 pages. Available in PDF, EPUB and Kindle. Book excerpt: Water Environment Modeling covers the formulations and applications of mathematical models that simulate water flow and chemical transport in rivers, lakes, groundwater, estuaries, coastal, and ocean waters. These models are used to evaluate the response of water environment to human interventions and serve as useful analytical tools for water pollution control and resource management. Simple and comprehensive modeling techniques and their practical applications are presented with examples and exercises, most of which are derived from actual case studies. In general, simple models can be solved analytically and comprehensive models require numerical solutions. While simple models are usually adopted for preliminary assessment of a particular water environment, comprehensive models are used to provide detailed spatial and temporal variations of pollutants in complex environments. The system-based models in the forms of integral equations are introduced as an alternative modeling approach. This textbook is ideal for advanced undergraduate students and graduate students in civil and environmental engineering and related academic fields. It is also suitable as a reference book for practicing engineers and scientists. Authors: Clark C.K. Liu is Emeritus Professor of the Department of Civil and Environmental Engineering at University of Hawaii and former Environmental Engineering Director of US National Science Foundation.
