| Summary: | This study investigated the effects of river ice and related flooding on the bank morphology and riparian vegetation along 655 km of the Peace River from Clayhurst, British Columbia to Fort Vermilion, Alberta. Regulation of this river since 1968 for the generation of hydroelectric power has caused a change in the flood regime and has resulted in variable channel adjustments and patterns of riparian succession. A major objective of this study was to determine how bank morphology and riparian vegetation might be influenced by disturbances created by ice jams and ice runs. Historical observations of ice jams have been focussed near the Town of Peace River, the largest population centre along the river. In order to examine frequency and magnitude of ice jam events for the remaining, sparsely populated reaches, a river-length reconnaissance was carried out. Both the direct physical effects of ice and the indirect effects of ice jam flooding on the channel margin were investigated. Bank morphology, sedimentary ... |
