  • Parking for Lake Shelbyville 4th of July Fireworks

    The U.S. Army Corps of Engineers is gearing up for the 4th of July at Lake Shelbyville. Fireworks will be launched at dusk from Ramp Point, located in Dam West Recreation Area. Lake Shelbyville has compiled a list of locations best suited for viewing the fireworks. Locations include: Dam West Recreation Area, Dam East Recreation Area, Lake Shelbyville Visitor Center, on top of the Lake Shelbyville Dam, and Dam West Overlook. At 8 p.m., the Dam Road will be closed to traffic prior to and during fireworks from the 9th street intersection to Dam East.

  • Fireworks prohibited on USACE sites around Fort Peck Lake

    FORT PECK, Mont. -- As the Fourth of July holiday approaches, the U.S. Army Corps of Engineers, Omaha District asks visitors to use extreme caution when recreating around Fort Peck due to the unusually dry conditions. The ignition of explosives or explosive devices, including fireworks or other pyrotechnics, on USACE lands or waters is prohibited. Campfires must be within designated metal fire rings. USACE strongly encourages everyone to check county and public lands burning and fire restrictions frequently as conditions may change.

  • Complex Network Analysis for Early Detection of Failure Mechanisms in Resilient Bio-structures

    Abstract: Bio-structures owe their remarkable mechanical properties to their hierarchical geometrical arrangement as well as heterogeneous material properties. This dissertation presents an integrated, interdisciplinary approach that employs computational mechanics combined with flow network analysis to gain fundamental insights into the failure mechanisms of high performance, light-weight, structured composites by examining the stress flow patterns formed in the nascent stages of loading for the rostrum of the paddlefish. The data required for the flow network analysis was generated from the finite element analysis of the rostrum. The flow network was weighted based on the parameter of interest, which is stress in the current study. The changing kinematics of the structural system was provided as input to the algorithm that computes the minimum-cut of the flow network. The proposed approach was verified using two classical problems three- and four-point bending of a simply-supported concrete beam. The current study also addresses the methodology used to prepare data in an appropriate format for a seamless transition from finite element binary database files to the abstract mathematical domain needed for the network flow analysis. A robust, platform-independent procedure was developed that efficiently handles the large datasets produced by the finite element simulations. Results from computational mechanics using Abaqus and complex network analysis are presented.

  • Galveston District supports nourishment project at Babe’s Beach

    This summer, Galveston Island’s Babe’s Beach, is getting a new round of fresh sand. The U.S. Army Corps of Engineers (USACE) Galveston District is partnering with the Galveston Park Board of Trustees, the City of Galveston, and the Texas General Land Office (GLO) in an ongoing effort to maintain and protect Galveston’s beaches – all at no additional cost to local residents. USACE is placing the Beneficial Use of Dredge Material (BUDM) or sand from its required dredging of Galveston’s ship channel to replenish this beach area. The BUDM is dredged and collected into a dredging ship, which is then pumped through pipes from the dredging ship onto the beach. This beach nourishment project is expected to take several months ending in late summer.
