Missouri River Temperature Effects in the Transition from Dunes to Plane Bed.
Abstract
Seasonal water-temperature changes influence stage-discharge and depth-discharge relations in rivers and in conveyance channels and navigation channels where water discharge is constant. The major influence is related to changes in bed configuration which accompanies water temperature changes. Stability analysis provides a theoretical basis for predicting bed-configuration changes, and using the theoretical relations with one empirical coefficient defined from field data, graphical relations are developed to use as design curves for estimating the velocity and flow depth, given the design unit water discharge, bed material size distribution, water temperature, and channel slope. The design curves are for channels with bed materials from 0.1 to 0.3 mm median diameters, water temperatures for 0 to 30 deg C, and slopes from 0.00005 to 0.0012.
