  • Development and Testing of the FRAME Tool on a 200-Mile Reach of the Lower Mississippi River

    Abstract: Understanding the likely long-term evolution of the Lower Mississippi River (LMR) is a challenging mission for the US Army Corps of Engineers (USACE) that remains difficult for conventional river engineering models. A new type of model is currently in development, tasked with revealing uncertainty-bounded trends in sediment transport and channel morphology over annual, decadal, and centennial timescales. The Future River Analysis and Management Evaluation (FRAME) tool is being designed with river managers and planners in mind to provide exploratory insights into plausible river futures and their potential impacts. A unique attribute of the tool is its hybrid interfacing of traditional one-dimensional hydraulic and sediment transport modeling with geomorphic rules for characterizing the morphological response. This report documents the development of a FRAME test-bed model for a 200-mile reach of the Mississippi River upstream of Vicksburg, Mississippi. This testbed allowed development and testing of the prototype FRAME tool in a data-rich environment. This work identified proposed future developments to provide river managers and planners with a fully functional tool for delivering insights on long-term morphological response in river channels across a variety of spatial and temporal scales.

  • Missouri River upper basin runoff forecast lowered due to dry conditions

    The updated 2025 calendar year runoff forecast for the Missouri River Basin above Sioux City, Iowa, continues to be below average. April runoff in the Missouri River Basin above Sioux City was 1.4 million acre-feet, 48% of average.

  • Missouri River upper basin runoff continues below average forecast

    The updated 2025 calendar year runoff forecast for the Missouri River Basin above Sioux City, Iowa, continues to be below average. March runoff in the Missouri River Basin above Sioux City was 2.3 million acre-feet, 76% of average.

  • Ohio Creek Urban Coastal Storm Risk Management Project: An Application of Engineering With Nature® Principles in Practice

    Purpose: The Engineering With Nature® (EWN®) program within the US Army Corps of Engineers (USACE) funds research projects occurring in a myriad of environments, including in marine coasts, freshwater coasts, and fluvial (riverine) systems. Yet there have been fewer projects documented where EWN principles have been applied in urban landscapes, particularly to manage flood risk, a main civil works mission of the USACE. Natural hazards including increased flashiness associated with intense rainfall events have prompted the need for more sustainable infrastructure solutions that reduce flood risks in urban areas, especially when such solutions desired by stakeholders are nature-based solutions. This technical note documents a flood risk management project in Norfolk, Virginia, that incorporates EWN principles in a tidal estuary environment that not only reduces flood risk, but also provides numerous other environmental, social, and economic benefits.

  • Virtual Missouri River water management public meetings set for April

    Two meetings to hear from the public about planned operation of the Missouri River Mainstem System will be held the first week in April.

  • Spring Missouri River public meetings to be virtual

    Virtual meetings on Missouri River Mainstem Reservoir system operations are in the process of being scheduled. Meeting dates and times will be announced as the details are finalized. In-person public meetings on Missouri River Mainstem Reservoir system operations, which were scheduled for March 19, 31 and April 2 have been canceled.

  • Gavins Point releases increasing for navigation flow support; Upper basin runoff stays below average

    The updated 2025 calendar year runoff forecast for the Missouri River Basin above Sioux City, Iowa, continues to be below average. February runoff in the Missouri River Basin above Sioux City was 1.0 million acre-feet, 91% of average. “Runoff into the reservoir system was slightly below average for the month of February and conditions across most of the basin remain dry,” said John Remus, chief of the U.S. Army Corps of Engineers’ Missouri River Basin Water Management Division.

  • Corps begins Phase I floodfight activities along the White River near Des Arc, Arkansas

    The Memphis District, U.S. Army Corps of Engineers (USACE) has begun Phase I floodfight activities along the White River in Arkansas due to high river stages. The area of current flooding is along the White River near Des Arc, Arkansas. During Phase I floodfight activities, USACE personnel deploy to the affected areas and monitor all federal flood control works including levees, flood walls and pumping stations. They will also continue to monitor rainfall amounts in the affected areas, and National Weather Service forecasts to determine if further action is warranted. USACE will deploy additional personnel and resources as required to help ensure the safety of life and property.

  • Below average runoff continues for upper Missouri River Basin in 2025

    The updated 2025 calendar year runoff forecast for the Missouri River Basin above Sioux City, Iowa, continues to be below average. January runoff in the Missouri River Basin above Sioux City was 0.7 million acre-feet, 92% of average. Runoff was near or below average for most of the Missouri River Basin, and most of the upper basin had below-normal precipitation.

  • Engineering With Nature: Natural Infrastructure for Mission Readiness at U.S. Navy and Marine Corps Installations

    Abstract: This book illustrates some of the current challenges and hazards experienced by military installations, and the content highlights activities at eight U.S. Navy and Marine Corps military installations to achieve increased resilience through natural infrastructure.
