Transport and Mixing of Buoyant Water from Small Mountainous Rivers : An Investigation of Estuarine Residence Timescales and Coastal Current Propagation

Creator:

Lemagie, Emily P.

Abstract:

Small rivers, such as those that line the Oregon coast, have been shown to deliver significant concentrations of suspended sediments and nutrients to estuaries and the coastal ocean during wet seasons during which winds are predominantly downwelling-favorable. The fate of the buoyant source water and of any suspended or dissolved...

AN ABSTRACT OF THE DISSERTATION OF Emily P. Lemagie for the
Dynamics of the Columbia River tidal plume

Creator:

Kilcher, Levi F.

Abstract:

This dissertation investigates the dynamics of the tidally modulated outflow from the Columbia River mouth using high resolution measurements of velocity, density and turbulent microstructure. At high tide, flow through the river mouth reverses from flood (onshore) to ebb (offshore). During ebb, buoyant fluid issues from the river mouth and...
