HYDROLOGIC AND HYDRAULIC PROCEDURES FOR FLOOD PLAIN DELINEATION
1. Purpose and objectives
Outlines the basic hydrologic and hydraulic investigations required
for flood risk mapping.
Discusses floods based on probability; floods from snowmelt and precipitation; large recorded floods; streamflow records; historical floods; stage-discharge relationships; hydraulic coefficients; elevations of high water marks; aerial photographs of large floods; river
cross-sections; streamflow regulation; meteorologic and physiographic data; lake and sea levels; flood frequency analysis; runoff from a specified input; and, hydraulic analysis to convert flood flow to a water surface profile.
Information on floods as described above.
Flood risk maps.
5. Operational requirements and restrictions
