In addition to its National Capital Region, U.S. Army Corps of Engineers (USACE) Institute for Water Resources (IWR) has designated centers:
Hydrologic Engineering Center (HEC), an organization within the Institute for Water Resources (IWR), is the designated Center of Expertise for the U.S. Army Corps of Engineers (USACE) in the technical areas of surface and groundwater hydrology, river hydraulics and sediment transport, hydrologic statistics and risk analysis, reservoir system analysis, planning analysis, real-time water control management and a number of other closely associated technical subjects. HEC supports USACE's field offices, Headquarters, and laboratories by providing technical methods and guidance, water resources models and associated utilities, training and workshops, accomplishing research and development, and performing technical assistance and special projects. The products that are developed from these activities are for the Corps but are available to the public and may be freely downloaded from the HEC web site.
The USACE is responsible for the operation and maintenance of the Nation's waterway system to insure efficient and safe passage of commercial and recreational vessels. IWR's Navigation and Civil Works Decision Support Center (NDC) exercises its Federal responsibility for establishing and maintaining a variety of water transportation information systems. The support and management of economically sound navigation projects is dependent upon reliable navigation data. The Corps has the Federal responsibility for establishing and maintaining a variety of U.S. water transportation information systems. These include databases and statistics pertaining to waterborne commodity and vessel movements, domestic commercial vessel characteristics, port and waterway facilities, lock facilities, lock operations, and navigation dredging projects. All public data are available through the NDC website.
The primary function of the Waterborne Commerce Statistics Center (WCSC), under the authority of the Rivers & Harbors Act of 1922, is to collect, process, distribute, and archive vessel trip and cargo data. The WCSC standard publications, Waterborne Commerce of the United States, is issued in five parts (one to cover each coast and a national summary).
The Risk Management Center (RMC) is a center of expertise. It was established in 2009 to improve management controls over infrastructure decisions, serve as an independent advisor to senior leadership, maintain and develop risk competencies, and ensure consistency in processes, application of criteria and decision-making. The mission of the RMC is to support Civil Works by managing and assessing risks for dams and levee systems across the Corps, to support dam and levee safety activities throughout the Corps, and to develop policies, methods, tools, and systems to enhance those activities. The RMC serves as a Corps-wide resource for risk-related tools, assessments, knowledge and methods. It is intended to offer a national perspective as well as support routine District and Major Subordinate Command (MSC) dam and levee safety activities. The RMC offers services to support dam safety; levee safety; and the Modeling, Mapping, and Consequence (MMC) Production Center.
