Traveltime, Unit-Concentration, Longitudinal-Dispersion, and Reaeration Characteristics of Upstream Reaches of the Yampa and Little Snake Rivers, Colorado and Wyoming

摘要

Two traveltime, unit-concentration, and dispersion analyses were made along a 58-mile reach of the Yampa River in Colorado when the average streamflow was approximately 100 and 3,400 cubic feet per second; three traveltime, unit-concentration, and dispersion analyses were made along a 72-mile reach of the Little Snake River in Wyoming and Colorado when the average streamflow was approximately 200, 600, and 1,600 cubic feet per second. Reaeration coefficients also were determined for the Yampa River reach when the average streamflow was approximately 100 cubic feet per second. Traveltime and unit-concentration simulations were made using a mathematical model. Data collected for the Little Snake River when the average streamflow was approximately 600 cubic feet per second were used as a check of model-simulation accuracy.
