Abstract

This study investigates the relation between channel changes, as mapped from aerial photography, and bed-material transport along Chilliwack River. Detailed mapping of channel features was completed for 5 dates between 1952 and 1991 using an analytical stereoplotter. Data were transfered to a geographic information system (GIS) to analyse changes during 4 consecutive periods. Significant morphologic change occurs roughly once every 5 years when flows are large enough to erode and entrain large volumes of bed material. In the absence of large floods, transport rates decline and vegetation begins to establish new floodplain
