Center Hill Dam is one of the multipurpose projects that make up the Corps of Engineers' system for development of the water resources of the Cumberland River Basin.
The new 110' x 600' Chickamauga Lock is being designed and constructed by the Nashville District, U.S. Army Corps of Engineers (USACE). The Judy Company (JC) has been contracted to construct a barrier wall consisting of an angled grout curtain.
The Tennessee Valley Authority (TVA) manages a large system which includes fossil and nuclear plants, dams, and reservoirs.
The Tennessee Valley Authority (TVA) River Operations, which regulates a system of 49 reservoirs spanning seven states, maintains Emergency Action Plans (EAPs) for dams throughout the Tennessee River System.
Geosyntec's client needed to assess redevelopment options for a 15-acre property that formerly housed a metal fabricating facility, now demolished, leaving only the concrete floor slabs.
Geosyntec installed solar powered water quality monitoring units at the Center Hill Dam to wirelessly transmit construction and other data to a real-time internet-based reporting system. Geosyntec installed solar powered water quality monitoring units at the Center Hill Dam to wirelessly transmit construction and other data to a real-time internet-based reporting system. The US Army Corp of Engineers (USACE) managed a $106 million rehabilitation of the Center Hill Dam in Tennessee. The massive rehabilitation effort included the installation of an approximately 200,000-square-foot barrier wall, the main protective feature in the seepage remediation project that extends more than 300 feet into the earthen embankment and underlying foundation bedrock. Center Hill Dam is the highest priority project of USACE's system for the development of the water resources of the Cumberland River Basin. As a major unit in the system, Center Hill Dam and Lake function to control the floodwaters of the Caney Fork River and contribute to the reduction of flood levels at municipal, industrial, and agricultural areas along the Cumberland and lower Ohio and Mississippi Rivers. In addition to the far-reaching effects of flood control, the dam contributes to the electrical power supply of the area through the generation of hydroelectric power. Monitoring of instrumentation during construction is a key method by which the USACE ensures not only the safety of the dam itself but the safety of the workers at the dam as well.
The Tennessee Valley Authority (TVA) manages a large system which includes fossil and nuclear plants, dams and reservoirs. TVA uses a series of numerical models to evaluate water temperature and water quality in its river-reservoir reaches to help meet regulatory criteria and identify potential regulatory issues and solutions. The modeling tools used by the TVA include CE-QUAL-W2, ADYN-RQUAL, and an internally developed model (BETTER). As part of a larger evaluation of its system-wide modeling tools, Geosyntec assisted TVA in updating their numerical models used for the fossil plant river-reservoir reaches to ensure the most appropriate tools and latest versions are being used. In addition, Geosyntec improved the accuracy of some of the models, to improve their ability to predict water temperature changes. This assists TVA hydrothermal personnel with maintaining regulatory compliance while maximizing the energy system production.
The Chickamauga Lock is a navigation lock on the Tennessee River, seven miles upstream of Chattanooga. Because the existing 80-year-old 60-foot-by-360-foot lock was no longer suitable for the larger barges now used by the transportation industry, the decision was made to replace the lock with a new 110-foot-by-600-foot lock. The new lock makes barge transport more efficient and solves structural issues caused by the existing concrete aggregate. As part of this project, Geosyntec provided geotechnical monitoring during the replacement, maintaining and operating an automated instrumentation and data-management system. This system was used to enhance worker safety while the lock was being installed to monitor the existing lock during construction and to verify structural performance consistent with design expectations.
Geosyntec developed an instrumentation and data management system to track, analyze, and visualize the ongoing lock removal. The system uses GIS technology to manage data associated with blasting, anchor installation, pile and wall installation.
Geosyntec developed the GroutTracker system to analyse and visualize grouting data collected during this grout curtain installation.The new 110' x 600' Chickamauga Lock is being designed and constructed by the Nashville District, United States Army Corps of Engineers (USACE). The Judy Company has been contracted to construct a barrier wall consisting of an angled grout curtain.
