Evaluation of Arkansas River Design Criteria for Stabilization and Rectification of the Channel
Abstract
This report covers work under part one of a two-part study for the Vicksburg District as part of their design studies for stabilization and canalization of the Lower Red River, Louisiana. Studies summarized in this report are limited to evaluation of the effectiveness of criteria used for similar stabilization work in providing navigable depths in the Lower Arkansas River, Arkansas, a similar project that has been in operation since 1969. Studies indicate that criteria used for stabilization in Arkansas River Pools 9 through 3 have been very successful in providing design depths, and that required maintenance dredging in the period 1978-1984 has been negligible, averaging about 150,000 cubic yards per year. Studies further indicated that deposition problems in Pool 2 (where maintenance dredging has averaged 430,000 cubic yards per year in the 1978-1984 period) probably are more related to pool characteristics than to design of stabilization work. Pool 2 is significantly longer and has more storage at normal pool level than Pools 9-3, an it is subject to open-river flow conditions more rarely than the other pools (spillway gates fully open about once in seven years, on the average, compared to annually at the other pools.
