Download or read book Changes in Morphology and Riparian Vegetation Following Flow Regulation, Peace River, 1968 and 1993 written by Michael Anthony Church and published by . This book was released on 1997 with total page 128 pages. Available in PDF, EPUB and Kindle. Book excerpt: Describes results of an investigation into the impacts of regulation on the Alberta portion of the Peace River channel and its associated vegetative cover downstream of the Bennett Dam in British Columbia, installed in 1967. Four representative reaches of the river totalling 500 kilometres were selected for examination of changes between 1968 and 1993. Study methodology involved constructing maps of river morphology and principal riparian vegetation communities from air photographs taken at various dates. In addition, extended vegetation mapping was provided on the 1993 maps to show the valley-side vegetation beyond the riparian zone. Morphological changes are summarized in 31 sub-reaches of 10-25 kilometres in length. River morphology is summarized in six major elements: water surface, unvegetated and vegetated bar surface, island surface, floodplain surface, and tributary alluvial fans within the floodplain. A dominant pattern of riparian succession is also noted.
