Welcome to the Institute for Water Resources Website 

The U.S. Army Corps of Engineers (USACE) Institute for Water Resources (IWR) was established to provide forward-looking analysis, cutting-edge methodologies, and innovative tools to aid USACE’s Civil Works program.

IWR strives to improve the performance of the USACE water resources program through analysis of emerging water resources trends and issues; development, distribution, and training in the use of state-of-the-art methods and models in the areas of planning, operations, and civil engineering; and national data management of results-oriented program and project information across Civil Works business lines. In addition to implementing this vision throughout core mission areas, IWR oversees seven Centers that provide targeted technical expertise and support.
