Download or read book Braided River Ecology written by Duncan Peter Gray and published by Science & Technical Publishing Department of Conservation. This book was released on 2007 with total page 50 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book The Braided River written by Samrat Choudhury and published by HarperCollins. This book was released on 2021-04-28 with total page 424 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book Fluvial Hydrosystems written by G.E. Petts and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 792 pages. Available in PDF, EPUB and Kindle. Book excerpt: Fluvial Hydrosystems provides a unified approach to the study of running waters and aims to provide a scientific basis for sustainable management of rivers. It differs from traditional texts in viewing rivers as structured, four-dimensional systems and integrating ecological and geomorphological approaches to provide a holistic perspective on river dynamics. Advanced students of geomorphology, ecology, environmental science, land use and civil engineering will all benefit from this wide-ranging and stimulating textbook.
