Morphology, Hydraulics and Sediment Transport of an Ice-Covered River: Field Techniques and Initial Data
This initial study of the ice-covered Tanana River, near Fairbanks, Alaska, attempted to 1) establish field methods for systematic and repetitive quantitative analyses of an ice-covered river's regime, 2) evaluate the instruments and equipment for sampling, and 3) obtain the initial data of a l...
