SEDHYD is the successor to the Federal Interagency Conferences on Sedimentation and Hydrologic Modeling. The first Federal Interagency Sedimentation Conference (FISC) was held in 1947. Since then, the Advisory Committee on Water Information, Subcommittee on Sedimentation (SOS) held the conference in 1963, 1976, 1986, 1991, 1996, 2001, 2006, 2010, and 2015. The Subcommittee on Hydrology (SOH) held their first Federal Interagency Workshops, “Hydrologic Modeling Demands for the 90s” in Fort Collins, Colorado, in 1993. After that workshop, the SOH decided to hold a broader series of conferences. Federal Interagency Hydrologic Modeling Conferences (FIHMC) were held in 1998, 2002, 2006, 2010, and 2015, covering models that addressed surface water quality and quantity issues. In 2015, the SOS and SOH adopted the SEDHYD name for the conference.

The combined conferences have provided about 2,400 technical papers and provided engineers and scientists with the opportunity to learn and exchange information about the latest developments and research related to sedimentation and hydrologic modeling. As a continuation of these conferences, SEDHYD provides an interdisciplinary mix of scientists and managers from government agencies, academia, and the business community to present recent accomplishments and progress in research and on technical developments related to sedimentation processes, hydrologic modeling, and the impact of sediment on the environment.

The SEDHYD conferences provide a mixed set of formats that include formal technical presentations, poster sessions, field trips, workshops, and computer model demonstrations. SEDHYD also hosts a student paper competition for cash prizes, as well as a Young Professionals’ Networking Reception.
