Human development has altered many rivers around the world. In the past, urban rivers were condemned as flood hazards, and load-reducing treatments were the only treatments applied to protect the surrounding communities against flooding. These treatments aim to collect precipitation from the surrounding surfaces quickly and divert the water using the most direct and spatially conservative means as possible- most often using concrete. These treatments have left rivers in ecologically non-functioning states. The channelization of the Los Angeles River in 1938 is a prime example of load-reducing treatment application. This river is unique because it has many constraints of urbanization and is located in a Mediterranean climate, resulting in water availability complications. Completed river projects in Mediterranean climates are presented and the lessons learned from these treatments are applied to the Los Angeles River. Alternative urban river restoration treatments have been successful at using flow-regime management, to return many ecosystem services to riparian ecosystems. Additional objectives were to compare 1.) costs and 2.) ecosystem service restoration success between eight main on-site and eight off-site alternative treatments applicable to urban rivers. Restoration success was evaluated based on the likelihood of restoring ecosystem services (goods and services that benefit humans) related to water quality and hydrologic regime. Due to physical urbanization constraints, the Los Angeles River will never become completely restored. However, this study found that specific reaches within the watershed can be restored to provide natural hydrologic function, retention, infiltration, filtration of water, and natural habitat for the watershed.

Our rivers are in crisis and the need for river restoration has never been more urgent. Water security and biodiversity indices for all of the world’s major rivers have declined due to pollution, diversions, impoundments, fragmented flows, introduced and invasive species, and many other abuses. Developing successful restoration responses are essential. Renewing Our Rivers addresses this need head on with examples of how to design and implement stream-corridor restoration projects. Based on the experiences of seasoned professionals, Renewing Our Rivers provides stream restoration practitioners the main steps to develop successful and viable stream restoration projects that last. Ecologists, geomorphologists, and hydrologists from dryland regions of Australia, Mexico, and the United States share case studies and key lessons learned for successful restoration and renewal of our most vital resource. The aim of this guidebook is to offer essential restoration guidance that allows a start-to-finish overview of what it takes to bring back a damaged stream corridor. Chapters cover planning, such emerging themes as climate change and environmental flow, the nuances of implementing restoration tactics, and monitoring restoration results. Renewing Our Rivers provides community members, educators, students, natural resource practitioners, experts, and scientists broader perspectives on how to move the science of restoration to practical success.

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.

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

Winner of the J. B. Jackson Prize from the Association of American Geographers Three centuries ago, the Los Angeles River meandered through marshes and forests of willow and sycamore. Trout spawned in its waters and grizzly bears roamed its shores. The bountiful environment the river helped create supported one of the largest concentrations of Indians in North America. Today, the river is made almost entirely of concrete. Chain-link fence and barbed wire line its course. Shopping carts and trash litter its channel. Little water flows in the river most of the year, and nearly all that does is treated sewage and oily street runoff. On much of its course, the river looks more like a deserted freeway than a river. The river's contemporary image belies its former character and its importance to the development of Southern California. Los Angeles would not exist were it not for the river, and the river was crucial to its growth. Recognizing its past and future potential, a potent movement has developed to revitalize its course. The Los Angeles River offers the first comprehensive account of a river that helped give birth to one of the world's great cities, significantly shaped its history, and promises to play a key role in its future.

With $2 billion spent annually on stream restoration worldwide, there is a pressing need for guidance in this area, but until now, there was no comprehensive text on the subject. Filling that void, this unique text covers both new and existing information following a stepwise approach on theory, planning, implementation, and evaluation methods for the restoration of stream habitats. Comprehensively illustrated with case studies from around the world, Stream and Watershed Restoration provides a systematic approach to restoration programs suitable for graduate and upper-level undergraduate courses on stream or watershed restoration or as a reference for restoration practitioners and fisheries scientists. Part of the Advancing River Restoration and Management Series. Additional resources for this book can be found at: www.wiley.com/go/roni/streamrestoration.
