This book was released on 1984 with total page 381 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Tanana River changes character in the vicinity of Fairbanks, from the braided pattern upstream of North Pole to the anastomosing or irregular meander pattern upstream of the Chena River confluence. This transition in planform is accompanied by a marked decrease in gradient and a change in dominant bed material from gravel to sand. Within the past 50 years the river has been affected by a variety of human activities, including flood control works, access causeways and gravel extractions. The river's cross-section shows large variations in width and depth from one location to another, but total cross-sectional area and mean velocity are relatively constant at a discharge of about 60,000 cfs, close to the mean annual flood. Sediment transport in the river averages about 360,000 tons per year of bed load, approximately equally divided between sand and gravel sizes, and about 28,000,000 tons per year of suspended load, of which about 35% is sand and the rest silt and clay. Natural channel processes are dominated by within-bank shifts in channel and bar patterns and cross-sectional shapes, erosion of the main floodplain and island being fairly localized and generally proceeding at modest rates. Details are discussed regarding observation of inferred response to groin construction and gravel extraction. Recommendations are given regarding impacts from human activities, alleviation of impacts, levee protection, further interpretive analysis and future monitoring of river behavior.

Available in PDF, EPUB and Kindle. Book excerpt: To determine if available data are useful in identifying the characteristics that contributed to erodibility of the banks along two reaches of the Tanana River, existing data on bank vegetation, soils, sediments, and permafrost were examined. Because these data were general and not collected for the purpose of site-specific analysis, an analytical approach was simple and did not include any statistical tests. The data were visually compared to the locations and estimated amounts of historical recession to evaluate if any relationships were obvious. The results of this analysis showed no useful relationships. Vegetation was similar in eroded and uneroded areas and its distribution did not show any obvious relationship to the locations of bank recession. Surface sediments and soils in the eroded and uneroded areas had little, if any, effect on bank erodibility because the river erodes the bank over its entire depth, which is well below this surface zone. The subsurface sediment from eroded and uneroded wells and along transects wtih high and low measured recession was similar. Permafrost occurrences are about equal in eroded and uneroded sites, although it appears that recession can be higher where permafrost is common than where it is absent. In most cases the existing data are either too general or not properly located to be useful in anticipating future locations of bank erosion. In order to predict future erosion, a field project should be initiated to evaluate the influences of bank characteristics and hydraulic forces on bank erosion rates.
