EP038:
Secondary Channels: Morphology, longevity, sediment processes, confluences, and distributaries





Session ID#: 23814

Session Description:
Secondary channels include any channel on or in a floodplain that conveys water and sediment to and from a main channel. They include side channels, distributary channels, anabranch channels, abandoned channels, overflow channels, chutes, and swales. Creation and enhancement of side channels has become a frequent goal as part of river rehabilitation and habitat creation or enhancement. Despite this goal, these channels are short lived and tend to fill or plug with sediment. Research efforts have focused on diversion and confluence angles with many advances coming from detailed study of hydraulics where the secondary and main channel meet. This session encourages submissions of work related to understanding side channels, particularly at the confluence and diversion from the main channel. We welcome submissions that include basic principles governing side channels, case studies of secondary channels, and any laboratory, numerical, and field experiments.
