POST-CONFERENCE FIELD TRIP

Fluid Flow and Sedimentation in the Lower Fraser River (Saturday August 6, 2011).

Trip Leaders: Mike Church (UBC), Ray Kostaschuk (University of Guelph and SFU) and Jeremy Venditti (SFU).

 

Field Trip Schedule - Saturday August 6 2011

The bus will leave SFU for Mission at 0800. The trip will be an approximately 4-hour cruise in a large touring boat from Mission to Steveston near the river mouth (about 75 km). The trip covers nearly all of the tidally influenced reach of the river, which is a single-thread, sand-bed reach that splits into several channels in the final 25 km in the delta. Commentary will cover a variety of topics on flow and sediment transport in the river, including the gravel-sand transition, bedform development and propagation, the salinity intrusion, and effects of dredging in the delta to facilitate deep-sea navigation. We will see and discuss boils and other surface evidences of CFS, and hope to visualize structures related to dunes and the salt-wedge using an acoustic Doppler current profiler. Participants will have 2 hours of free time in historic Steveston prior to the 4:00 PM departure of the bus for SFU
