  • Characterization and Rheological Examination of Charleroi Mix 2 Paste Constituents

    Abstract: This technical report details the testing plan, methodology, and results used to characterize the paste constituent materials for Charleroi Concrete Mixture 2. Raw materials were characterized for physical and chemical properties of interest including chemical composition, mineralogy, particle size, and absorption capacity. Isothermal calorimetry was used to study the reactivity of constituent materials, and rotational rheology was used to study the impact of various constituent materials on the expected workability and fluidity of the composite paste.
  • Pier Analysis Tool: User’s Manual

    Abstract: This report documents the development of a rapid structural load-capacity assessment capability for ship docking and offloading structures (i.e., piers) and automation of the assessment technique into a user-friendly personal computer–based tool referred to herein as the Pier Analysis Tool (PAT). This capability provides a quick first-cut assessment of the load-bearing capacity of pier structures in terms of maximum allowable ship mooring loads and allowable weights for typical commercial and military vehicles and equipment associated with military discharge operations. The report covers the technical basis for the structural analyses along with detailed computational examples. It also provides a detailed user guide for PAT.
  • Corps Shoaling Analysis Tool (CSAT) User Guide

    Abstract: The Corps Shoaling Analysis Tool (CSAT) is a suite of computational routines for evaluating shoaling rates in navigation channels maintained by the US Army Corps of Engineers (USACE). This is achieved using survey data from the eHydro enterprise hydrographic survey database. At the local scale, CSAT’s outputs are useful for understanding historical shoaling trends and identifying shoaling hotspots, while enterprise-level shoaling forecasts support Operations and Maintenance (O&M) planning over a 5-year time horizon. This user guide provides practical, step-by-step instructions for new CSAT users who wish to download, install, and run the tool. Later sections provide insight into CSAT’s advanced features while also describing the methods and assumptions that underlie the calculations.
