  • National Sediment Placement Data Viewer Users Guide

    Purpose: This US Army Corps of Engineers (USACE) Regional Sediment Management (RSM) technical note serves as a user’s guide for the RSM National Sediment Placement Data Viewer. This application was created utilizing over 20 yr* of detailed and verified USACE dredging data, giving users an interactive web-based tool that takes these datasets and displays them on a national map, viewable at the district or project scale. The Data Viewer will quantify the total cubic yards dredged, disposed, and/or beneficially used based on the user selected parameters. Detailed information on the datasets utilized and the verification processes followed to create this application can be found in ERDC/TN RSM-22-4, USACE Navigation Sediment Placement: An RSM Program Database (1998 – 2019) (Elko et al. 2022). This technical note attempts to define each of the inputs/outputs given from the Data Viewer and then provide a step-by-step example of utilizing the Data Viewer, accessed here: https://www.arcgis.com/apps/MapSeries/index.html?appid=0ea8fc0a956f46068428c862e7497233

  • Techniques for Developing Bars and Islands in Incising Channels

    Abstract: Sandbars and islands provide important nesting and foraging habitat for birds (including listed species) and shallow water habitat for many aquatic species in riverine ecosystems. In-stream habitat is especially important in incised channels lacking floodplain connectivity, with channel bars providing important riparian habitat. However, some river management practices significantly alter and sometime eventually eliminate these important habitats. Several US Army Corps of Engineers districts are planning or actively building instream bars and islands using flow management and/or instream structures. Sister agencies (e.g., US Bureau of Reclamation) have similar initiatives downstream of their reservoir structures. This report outlines considerations for establishing and managing sandbar and island features. It presents a compilation of proven techniques for promoting sandbar and island development and for reducing erosion of these features.

  • USACE reduces target flows from Lake Okeechobee to the Caloosahatchee

    The U.S. Army Corps of Engineers (USACE) Jacksonville District will reduce target flows from Lake Okeechobee to the Caloosahatchee beginning Saturday, July 9, as lake levels remain steady and local basin runoff has been adequate to maintain salinity levels in the estuary. The releases to the Caloosahatchee Estuary will target a pulse release at a 7-day average of 750 cubic feet per second (cfs) from the W.P. Franklin Lock and Dam (S-79). This is a reduction from the 1,000 cfs targeted pulse release that has been in effect since April 30.
