  • Field Jet Erosion Tests on Benbrook Dam, Texas

    Abstract: This report summarizes the results of eight field Jet Erosion Tests (JETs) performed on Benbrook Dam, TX. The results from these tests will be used by the U.S. Army Corps of Engineers, Fort Worth District, in assessments of the erosion resistance of the Benbrook Dam with regards to possible overtopping by extreme flooding. The JETs were performed at four different locations, i.e., two locations at the lowest crest elevation and two locations at the mid-slope face of the downstream embankment. Variations in estimated critical hydraulic shear stress and erosion rate values may have been caused by differences in soil composition, i.e., when the material changed from silt/sand to clay. The resulting values of the Erodibility Coefficient, Kd, and Critical Stress, τc, are very useful information in assessing the stability of Benbrook Dam during an overtopping event. Because of the observed natural variability of the materials, combining the erosion parameters presented in this report with the drilling logs and local geology will be imperative for assessing erosion-related failure modes of Benbrook Dam.
  • USACE team successfully completes miter gate repairs at Markland Locks and Dam

    For approximately two years, Markland Locks and Dam’s auxiliary chamber, in Warsaw, Kentucky, has been closed for repair. However, as of Dec. 4. 2021, the 600-foot chamber has reopened to navigation traffic. The chamber was originally closed due to an issue with the upper miter gate, and during that time all traffic continued to pass through the primary chamber. The Regional Heavy Capacity Repair Fleet has been on site at the project since August working to repair the miter gates.

  • Lockmaster’s view – The McAlpine Locks and Dam

    Within the entire length of the Ohio River, there was only one place where rock reef extended across the river for a stretch of three miles – The Falls of the Ohio. This area of water was a low water slope, dropping around thirty feet over the three miles and made it practically impassable by cargo and transportation vessels in the early 1800s except when the water level was high; even then, it was treacherous. This article consists of a safety summary and a personal interview from the McAlpine Locks and Dam Lockmaster, Jay Rickman.
