FLDWY (TR): Floodway Determination Computer Program. Hydraulic Formulas. PONDS: – Planning, Design, Construction - USDA Handbook # (book) SITES: Water Resources Site Analysis Computer Program (replaces DAMS2). STEADY FLOW WITH HEC-RAS This course teaches the concepts of open channel flow. It covers: data requirements, HEC-RAS input requirements, application of bridge and culvert routines, channel modification analysis, floodway determination, and output analysis. The River Analysis System (HEC-RAS) software will be included in lectures and workshops. The following Computer Program Documentation is provided as reference material. HEC no longer distributes these computer programs. CPD-1a, HEC-1 User's Manual. CPD-2, HEC-2 User's Manual. CPD-4, HEC-4 User's Manual. CPD-5, HEC-5 User's Manual.

Floodway revisions. A computer program developed by the US Army Corps of Engineers Hydrologic Engineering Center for use in simulating the surface runoff response of a river basin to precipitation. HEC A step-backwater program developed by the US Army Corps of Engineers Hydrologic Engineering Center for use in calculating water-surface profiles for steady. Approximate methods are recommended for rapid determination of the floodplain, floodway boundaries, and inundation area mapping, while sophisticated computer . Determination of the status of a community's participation pation in the NFIP is provided in the ''National Flood Insurance Program Community Status Book" which is published bi-monthly for each State and is current year model and current year floodway model. 3. Copy of computer printouts (input, computation, and output) for the.
Regional PO approval should be obtained in choosing the standard step-backwater computer program. 2. Floodway Determination. The existing floodway configuration should be retained wherever possible. If it is not possible to retain the existing configuration, then the Regional PO should be contacted for guidance. The floodway plays an important role in flood modeling. In the United States, the Federal Emergency Management Agency requires the floodway to be determined using an approved computer program for developed communities. It is a local government’s interest to minimize the floodway area because encroachment areas may be permitted for human. regular program, the NFlP map is a FIRM, but no regulatory floodway has bccn established. Information on community participation in the NFIP is provided in the "National Flood Insurance Program Community Status Book" which is published bimonthly for each State and is available through the Headquarters of FEMA. Coordination With FEMA. The National Flood Insurance Program (NFIP) is a program created by the Congress of the United States in through the National Flood Insurance Act of (P.L. ). U.S. Congress has the twofold purposes of the NFIP to share the risk of flood losses through flood insurance and to reduce flood damages by restricting floodplain development.
