The primary goal of HEC is to support the nation in its water resources management responsibilities by increasing the Corps technical capability in hydrologic engineering and water resources planning and management. An additional goal is to provide leadership in improving the state-of-the-art in hydrologic engineering and analytical methods for water resources planning.
By means of programs in research, training, planning analysis, and technical assistance, efforts are made to be aware of the problems and needs of the Corps and the nation. A commitment is also made to keep abreast of the latest developments throughout the profession, and to make use of this information in a manner best suited to the needs of the Corps.
HEC increases the effectiveness of the Corps and the profession by bridging the gap between the academic community, practicing hydrologic engineers, and planning professionals. Research or training activities that can be best accomplished by universities is not undertaken. HEC incorporates state-of-the-art procedures and techniques into manuals and comprehensive computer programs. The procedures are made available to the Corps, United States and international professionals through an effective technology transfer system of technical assistance, publications, video tapes, and training.
