The program develops or interprets site-specific data on obstructions to flood flows; flood formation and timing; flood depths or stages; floodwater velocities and the extent, duration and frequency of flooding. It also provides information on natural and cultural floodplain resources before and after the use of floodplain management measures.

On a larger scale, the program provides assistance and guidance in the form of “Special Studies” on all aspects of floodplain management planning, including the possible impacts of off-floodplain land use changes on the physical, socio-economic and environmental conditions of the floodplain. Special Studies are accomplished at 100 percent Federal cost. Funding for these studies is very limited and competitive. Special Studies can range from helping a community identify present or future floodplain areas to a broad assessment of the various floodplain management alternatives. Some of the most common types of Special Studies include:

• Floodplain Delineation/Flood Hazard Evaluation Studies
• Dam Break Analysis Studies
• Flood Warning/Preparedness Studies
• Regulatory Floodway Studies
• Comprehensive Floodplain Management Studies
• Urbanization Impact Studies
• Storm Water Management Studies
• Hydrologic, hydraulic and sediment transport modeling

Studies are conducted under the program to improve the methods and procedures for mitigating flood damages. Guides and pamphlets also are prepared on flood proofing techniques, floodplain regulation, floodplain occupancy, natural floodplain resources and other related aspects of floodplain management.

Upon request, program services are provided to state, regional and local governments, Native American Tribes and other non-Federal public agencies without charge, based on available funding. All requesters are encouraged to furnish available field survey data, maps, historical flood information and the like to help reduce the cost of services.
