This book was released on 2022 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Flooding events around the world cost billions (USD) in damages each year. For decades, engineers have combated flood related damages by implementing flood mitigation controls such as channelization, levees or berms, and armoring. Recent advances in the study of river dynamics, however, have challenged the efficacy of these traditional flood mitigation techniques and pose that these structures are disconnecting channels from their floodplains, increasing flow rates, and contributing to more erosion. The effects of climate change combined with future predictions of increased storm frequency and intensity make it necessary to revise flood hazard mitigation strategies. A more nature-based alternative to building structural defenses, is to reconnect disconnected floodplains and conserve those floodplains that are already well-connected. A well-connected floodplain allows floodwaters to overtop the channel banks more frequently to dissipate flood energies and slow stream flow thereby decreasing downstream damages. Additional benefits include provision of habitat and improved water quality. When choosing techniques and locations for floodplain conservation and reconnection, planners have a multitude of concerns to consider (e.g., water quality, flood resiliency, habitat improvement, project effectiveness, existing land use, budget, and lost opportunity costs). Considering all stakeholder objectives within budgetary constraints is a difficult and complex process, made even more challenging because these objectives often compete. Consequently, there is a need for computational tools that can optimize restoration locations and conservation strategies to help planners synthesize, justify, and visualize design choices. To help alleviate the uncertainty in planning for improvement projects, multi-objective optimization was performed to optimize both the locations and techniques for conservation and restoration while considering the tradeoffs between multiple stakeholder objectives. Three case studies in Vermont are used for illustration. In the first, a tool is developed that semi-automates the extraction and analysis of five evaluation parameters from a 2D hydraulic model (2D Hydrologic Engineering Center's River Analysis System, 2D HEC-RAS) to compare hydraulic effectiveness of four floodplain reconnection scenarios on the Black Creek. This same tool is leveraged in the second case study along a section of the Mad River to develop an n-dimensional objective function to rank floodplain reconnection techniques while considering multiple stakeholder objectives (i.e., enhanced flood resiliency, improved water quality, and minimized socioeconomic impacts). The third case study in the Winooski River watershed, applies an evolutionary algorithm to a geospatial database of river network connectivity data on the basin scale to provide planners with a suite of optimal conservation locations that balance the tradeoffs between stakeholder goals including flood resiliency, water quality, and cost effectiveness. The tools developed aided in the advancement of a more holistic approach to floodplain conservation and reconnection design creating a more efficient method to narrow in on optimal sites at the watershed and reach scales considering multiple stakeholder objectives/concerns.

Download or read book River Restoration written by Stephen Darby and published by John Wiley & Sons. This book was released on 2008-02-28 with total page 328 pages. Available in PDF, EPUB and Kindle. Book excerpt: River restoration projects are designed to recreate functional characteristics within a context of physical stability. They tend to focus on the development and application of geomorphic principles for river restoration design. Due to different models obtaining different results on the same problem, incomplete or absent data, and climatic/social/cultural changes, the designers and managers of such projects frequently face high levels of uncertainty. This book will provide a systematic overview of the issues involved in minimizing and coping with uncertainty in river restoration projects. A series of thematic sections will be used to define the various sources of uncertainty in restoration projects and how these show at different points in the life cycle (design, construction and post-construction phases) of restoration projects. The structure of the book will offer a rational theoretical analysis of the problem while providing practical guidance in managing the different sources of uncertainty. A wide range of case studies will be included from Europe, North America and Australasia

Download or read book River Restoration written by Bertrand Morandi and published by John Wiley & Sons. This book was released on 2021-09-20 with total page 388 pages. Available in PDF, EPUB and Kindle. Book excerpt: River Restoration River restoration initiatives are now widespread across the world. The research efforts undertaken to support them are increasingly interdisciplinary, focusing on ecological, chemical, physical as well as societal issues. River Restoration: Political, Social, and Economic Perspectives provides a comprehensive overview of research in the field of river restoration in humanities and the social sciences. It illustrates how, in the last thirty years or so, such approaches have evolved and strengthened within the restoration sciences. The scientific community working in this domain has structured itself, often regionally and circumstantially, to critically assess and improve restoration policies and practices. As a research field, river restoration tackles three thematic axes: Human-river interactions – especially perceptions and practices of rivers, and how these interactions can be changed by restoration projects Political processes, with a particular interest in governance and decision-making, and a specific emphasis on the question of public participation in restoration projects Evaluation of the social and economic benefits of river restoration River Restoration: Political, Social, and Economic Perspectives encompasses these three topics, and more, to provide the reader with the most up-to-date and holistic view of this constantly evolving area. The book will be of particular interest to human and social scientists, biophysical scientists (hydrologists, geomorphologists, ecologists), environmental scientists, public policy makers, design or planning officers, and anyone working in the field of river restoration.
Download or read book A Systems Approach for River and River Basin Restoration written by Theodore Endreny and published by MDPI. This book was released on 2021-05-27 with total page 204 pages. Available in PDF, EPUB and Kindle. Book excerpt: Communities increasingly find that the water quality, water levels, or some other resource indicator in their river basins do not meet their expectations. This discrepancy between the desired and actual state of the resource leads to efforts in river basin restoration. River basins are complex systems, and too often, restoration efforts are ineffective due to a lack of understanding of the purpose of the system, defined by the system structure and function. The river basin structure includes stocks (e.g., water level or quality), inflows (e.g., precipitation or fertilization), outflows (e.g., evaporation or runoff), and positive and negative feedback loops with delays in responsiveness, all of which function to change or stabilize the state of the system (e.g., the stock of interest, such as water level or quality). External drivers on this structure, together with goals and rules, contribute to how a river basin functions. This book reviews several new research projects to identify and rank the twelve most effective leverage points to address discrepancies between the desired and actual state of the river basin system. This book demonstrates that river basin restoration is most likely to succeed when we change paradigms rather than try to change the system elements, as the paradigm will establish the system goals, structure, rules, delays, and parameters.

Download or read book Modeling Water Resources Management at the Basin Level written by Daene C. McKinney and published by IWMI. This book was released on 1999 with total page 71 pages. Available in PDF, EPUB and Kindle. Book excerpt: The world is facing severe and growing challenges in maintainig water quality and meeting the rapidly growing demand for water resources. In addition, water used for irrigation, the largest use of water in most developing countries, will likely have to be diverted increasingly to meet the needs of urban areas and industry whilst remaining a prime engine of agricultural growth. Finally, environmental and other in-stream water demands become more important as economies develop. The river basin has been acknowledged to be the appropriate unit of analysis to address these chanllenges facing water resources management: and modeling at this scale can provide essential information for policy makers in their decisions on allication of resources. This paper reviews the state of the art of modeling approaches to integrated water resources management at the river basin scale, with particular focus on the potential of coupled economic hydrologic models, and concludes with directions for future modeling exercises.

Download or read book River Quality written by David A. Dunnette and published by CRC Press. This book was released on 1997-01-28 with total page 484 pages. Available in PDF, EPUB and Kindle. Book excerpt: What is involved in restoring a river? River Quality: Dynamics and Restoration answers this question through a series of articles and case studies written by some of the field's leading researchers and practitioners. The first part of the book covers the physical, chemical, and biological dynamics of a river system. The second part describes monitoring programs and remedial measures used to restore river systems back to healthy and functional states. The Willamette River in Oregon and the Vistula River in Poland are used to illustrate the dynamic and restoration processes. Each river is in a different stage of restoration and is subjected to different degrees of stress from agriculture, industry, and urbanization. The Willamette is an internationally cited example of a restored river, while the Vistula is a river that has just recently begun the restoration process. Contrasts and comparisons of the two river systems enable readers to learn the limitations of restoration processes and what is involved in the different stages of restoration.
