Book Description
A braided river is one that, over some part of its length, flows in multiple, mobile channels across a gravel floodplain. In New Zealand, many braided rivers remain in a relatively unmodified condition, but increasing demands for hydro-electricity generation, irrigation, gravel extraction and flood protection works are placing pressure on these systems. However, apart from a limited number of studies on the ecology of individual species or reaches, there has been little coordinated ecological research to assess the overall values and function of braided river ecosystems in New Zealand. This review summarises the international and New Zealand literature on braided rivers, with particular emphasis on benthic invertebrate ecology. Braided rivers typically experience short-term channel migration within the active bed and greater lateral channel migration across the entire floodplain in the longer term. Channel migration occurs because steep headwater tributaries supply highly variable discharges and mobile erodable substrates to the mainstem. Braided rivers typically possess extended floodplains, which may contain a mosaic of floodplain habitats ranging from highly unstable main-stem channels to stable spring complexes. Main channel aquatic invertebrate communities are frequently low in diversity and dominated by the leptophlebiid mayfly Deleatidium spp., but also chironomids and elmid beetles. In contrast, floodplain springs can have highly diverse communities rich in amphipods, mayflies, caddis, snails and chironomids. Groundwater and floodplain pond habitats also occur frequently and can contain several specialist taxa. Braided rivers and their floodplains are spatially complex, temporally dynamic habitats with high landscape- and reach-scale biodiversity values. The challenge facing managers is to protect this biodiversity within the context of increasing human demands on the rivers. This report highlights the particular threats and management issues associated with braided rivers in New Zealand and identifies areas where future research is required.

Book Description
The Brahmaputra is by some margin the largest river in India. After its confluence with the Ganga in Bangladesh, it becomes the largest in Asia. In The Braided River, journalist Samrat Choudhury sets out to follow its braided course from the edge of Tibet where it enters India down to where it meets the Ganga at a spot marked by the biggest red light district in Bangladesh. Along the way, he meets suspicious Indian spies, gets packed off on the back of a cement truck by soldiers, visit a shelter home for baby rhino and elephant orphans in Kaziranga, and hops from river island to riverside town meeting the locals. The tales of these encounters spice up a story that weaves in the history of the emergence of the border between India and China in Arunachal Pradesh, the formation of the Assamese identity -- a matter of great contemporary relevance owing to the National Register of Citizens and the Citizenship (Amendment) Act -- and the ecological challenges posed by proposed dams. This is a genre-bending book that touches upon several hot-button issues -- environmental, military and political -- as it blends travel, memoir and history with the present.

Book Description
Rivers are important agents of change that shape the Earth's surface and evolve through time in response to fluctuations in climate and other environmental conditions. They are fundamental in landscape development, and essential for water supply, irrigation, and transportation. This book provides a comprehensive overview of the geomorphological processes that shape rivers and that produce change in the form of rivers. It explores how the dynamics of rivers are being affected by anthropogenic change, including climate change, dam construction, and modification of rivers for flood control and land drainage. It discusses how concern about environmental degradation of rivers has led to the emergence of management strategies to restore and naturalize these systems, and how river management techniques work best when coordinated with the natural dynamics of rivers. This textbook provides an excellent resource for students, researchers, and professionals in fluvial geomorphology, hydrology, river science, and environmental policy.

Book Description
Braided Waters sheds new light on the relationship between environment and society by charting the history of Hawaii’s Molokai island over a thousand-year period of repeated settlement. From the arrival of the first Polynesians to contact with eighteenth-century European explorers and traders to our present era, this study shows how the control of resources—especially water—in a fragile, highly variable environment has had profound effects on the history of Hawaii. Wade Graham examines the ways environmental variation repeatedly shapes human social and economic structures and how, in turn, man-made environmental degradation influences and reshapes societies. A key finding of this study is how deep structures of place interact with distinct cultural patterns across different societies to produce similar social and environmental outcomes, in both the Polynesian and modern eras—a case of historical isomorphism with profound implications for global environmental history.

Book Description
The Missouri River Ecosystem: Exploring the Prospects for Recovery resulted from a study conducted at the request of the U.S. Environmental Protection Agency and the U.S. Army Corps of Engineers. The nation's longest river, the Missouri River and its floodplain ecosystem experienced substantial environmental and hydrologic changes during the twentieth century. The context of Missouri River dam and reservoir system management is marked by sharp differences between stakeholders regarding the river's proper management regime. The management agencies have been challenged to determine the appropriate balance between these competing interests. This Water Science and Technology Board report reviews the ecological state of the river and floodplain ecosystem, scientific research of the ecosystem, and the prospects for implementing an adaptive management approach, all with a view toward helping move beyond ongoing scientific and other differences. The report notes that continued ecological degradation of the ecosystem is certain unless some portion of pre-settlement river flows and processes were restored. The report also includes recommendations to enhance scientific knowledge through carefully planned and monitored river management actions and the enactment of a Missouri River Protection and Recovery Act.

Book Description
Puget Sound is a magnificent and intricate estuary, the very core of life in Western Washington. Yet it's also a place of broader significance: rivers rush from the Cascade and Olympic mountains and Canada's coastal ranges through varied watersheds to feed the Sound, which forms the southern portion of a complex, international ecosystem known as the Salish Sea. A rich, life-sustaining home shared by two countries, as well as 50-plus Native American Tribes and First Nations, the Salish Sea is also a huge economic engine, with outdoor recreation and commercial shellfish harvesting alone worth $10.2 billion. But this spectacular inland sea is suffering. Pollution and habitat loss, human population growth, ocean acidification, climate change, and toxins from wastewater and storm runoff present formidable challenges. We Are Puget Sound amplifies the voices and ideas behind saving Puget Sound, and it will help engage and inspire citizens around the region to join together to preserve its ecosystem and the livelihoods that depend on it.
