Lake Dardanelle, Arkansas River; Hydraulic Model Investigation.
Abstract
Lake Dardanelle is a 51-mile-long reservoir formed by Dardanelle Lock and Dam which is located at mile 205.5 on the Arkansas River. The lake was designed to provide head for power, depth for navigation, and a trap for a considerable volume of sediment. The river was realigned and stabilized in the portion of the lake upstream of mile 238.4 with plans for progressive improvement of the reach downstream as deposition and channel development indicated the need for such improvements. Water was impounded in 1964; and by 1972, depositon had accumulated in the vicinity of Horse Head Creek such that it was beginning to hinder navigation. This study was conducted to determine the type and location of training and stabilization structures needed to develop a satisfactory navigation channel downstream of mile 238.4 and to provide a satisfactory channel approaching the navigation span of the proposed highway bridge at mile 234.9. A movable-bed model reproduced the reach of the Arkansas River and adjacent overbank area from mile 238.5 to 231.3 to scales of 1:120 horizontally and 1:80 vertically.
