Abstract: This report includes the Geotechnical analyses related to the irrigation portion of the Bayou Meto Comprehensive Study. The project is located in the Bayou Meto Basin in the vicinity of Lonoke, Arkansas. The project consists of a large water distribution system to provide supplemental agricultural water supply to the depleted areas of the Bayou Meto Basin while preserving the groundwater resource. The project area includes portions of Prairie, Arkansas, Lonoke, Jefferson and Pulaski counties in eastern Arkansas. The general area begins about 10 miles east of Little Rock, Arkansas and extends approximately 60 miles to the southeast. See Plate II-1 for a general location map. The plan of improvement for the Bayou Meto area consists of a major pumping station located at the Arkansas River, 3 other pumping stations and a network of new canals, existing channels, pipelines, and associated channel structures to accomplish interbasin transfer of surface water to the water depleted areas. This report will address the major features of the project: a 1750 cubic feet per second (cfs) pumping station (Pumping Station #1), a 625 cubic feet per second (cfs) pumping station (Pumping Station #2), a 260 cubic feet per second (cfs) pumping station (Pumping Station #3), a 125 cubic feet per second (cfs) pumping station (Pumping Station #4), 12 gated control structures located in the main distribution canals, 3 pumping station reservoirs, general stability of the canals and levee embankment system and the estimated seepage loss throughout the network of the water distribution system. There are a significant number of other smaller structures or features that will not be addressed in this report due to the magnitude of this project. These features include gated conduit structures, gated and lateral canal turnouts, bridges, retaining walls, inverted box siphons, inverted siphons (natural drainage), inverted pipe siphons (road crossings and natural drainage), wasteways, small horsepower pumps, and weirs on existing streams. More detail on these structures can be found in Section IV - Structural, Mechanical & Electrical. A location map of the project limits, new canal alignment, some pipeline alignment are shown on Plate II-6. Corps of Engineers design criteria and standards were used for the Geotechnical design presented in this study.
