  • Upper Missouri River basin forecast runoff remains well below normal; water conservation measures continue

    Reservoir inflows in the Missouri River basin above Sioux City, Iowa, were well-below average in March. The March runoff of 1.5 million acre-feet (MAF) was 48% of average for the month. The updated 2022 upper Basin runoff forecast is 17.8 MAF, 69% of average, approximately 2.6 MAF less than the March 1 forecast. 

  • Risk-Based Prioritization of Operational Condition Assessments: Jennings Randolph Case Study

    Abstract: The US Army Corps of Engineers (USACE) operates, maintains, and manages over $232 billion worth of the Nation’s water resource infrastructure. Using Operational Condition Assessments (OCA), the USACE allocates limited resources to assess asset condition in efforts to minimize risks associated with asset performance degradation, but decision makers require a greater understanding of those risks. The analysis of risk associated with Flood Risk Management assets in the context of its associated watershed system includes understanding the consequences of the asset’s failure and a determination of the likelihood that the asset will perform as expected given the current OCA ratings of critical components. This research demonstrates an application of a scalable methodology to model the probability of a dam performing as expected given the state of its subordinate gates and their components. The research team combines this likelihood with consequences generated by the application of designed simulation experiments with hydrological models to develop a measure of risk. The resulting risk scores serve as an input for an optimization program that outputs the optimal set of components to conduct OCAs on to minimize risk in the watershed. Proof-of-concept results for an initial case study on the Jennings Randolph Dam are provided.

  • USACE receives millions in Federal funding for Ports of Brownsville, Corpus Christi, Galveston and Houston

    More funding is on the way for several ship channel improvement projects in Texas, including the Brazos Island Harbor (Port of Brownsville), the Corpus Christi Ship Channel (Port of Corpus Christi Authority), the Galveston Harbor and Channel (Port of Galveston), and the Houston Ship Channel (Port of Houston). The Biden Administration announced March 29, that it will invest more than $2.7 billion in funding to [300] Army Corps projects throughout the country focused on strengthening ports and waterways in addition to other funding already received by the ports for projects. The Biden Administration is invested a total of nearly $17 billion in new funding and other supplemental appropriations in fiscal year 2022 and 2023 for over 800 projects across 55 states and territories.

  • Setup and Data Collection Process of an Acoustic Doppler Velocimeter (ADV) in a Laboratory Setting

    Abstract: The purpose of this Coastal and Hydraulics Engineering Technical Note (CHETN) is to outline experimental set up and the data collection process of an Acoustic Doppler Velocimeter (ADV) in a laboratory setting. The Nortek Vectrino ADV will be referenced in this CHETN as will the Nortek Comprehensive Manual for Velocimeters (Nortek AS 2018). Note that Nortek no longer sells the Vectrino, but the Vector, which is similar to the Vectrino aside from only having one configuration, is available.
