Influences Of Channel Dredging On Avulsion Potential At The Atchafalaya River, Gordon William Mccain
Influences Of Channel Dredging On Avulsion Potential At The Atchafalaya River, Gordon William Mccain
Graduate Theses and Dissertations
In 1950, the U.S. Army Corps of Engineers (USACE) reported a rapid increase of water discharge from the Mississippi River to its distributary channel; the Atchafalaya River. If not prevented by man-made structures, the complete capture of the Mississippi River by the Atchafalaya River was predicted. The USACE report cites multiple causes for the observed increase in discharge partitioning, yet fails to assess the largescale channel dredging operations conducted throughout the Atchafalaya River Basin during the 1930's and 1940's as a potential cause for the increased discharge. To assess the role man-made interventions, specifically channel dredging, played in the increase …
Statistical Analysis Of Fluvial Channel Belts, Kyle Ryan Spencer
Statistical Analysis Of Fluvial Channel Belts, Kyle Ryan Spencer
Graduate Theses and Dissertations
As meandering rivers laterally migrate over time, they build channel belts. The accumulation of all previous flow paths creates the channel belt. To better understand these ancient rivers, modern river systems are being mapped to find statistical relationships between current flow path and the channel belt of river systems. It is important to examine a wide range of systems in terms of age, size, and location. The rivers are being mapped using an ImageJ, interpretations from Saucier (1994) and Google Earth. Three channel belt morphologies are mapped for 15 modern channel belts; the width of the river in relation to …
