Spectral Analysis of Columbia River Estuary Currents.

Abstract

A spectral analysis study was conducted to determine if wind-induced currents within the Columbia River estuary were sufficiently large to justify their inclusion in a numerical model of sediment transport within the estuary. Completion of the analysis showed that wind-induced current velocities were considerably less than 0.5 fps and consequently have little effect on instantaneous sediment transport. Keywords: Oregon; Washington(State); Columbia River; Estuary; River currents; Mathematical models; Sediment transport; Spectrum analysis; Winds.
