Floodplain Management Defined

“Floodplain management is a decision making process the goal of which is to achieve wise use of the nation’s floodplains. ‘Wise use’ is any activity or set of activities that is compatible with the risk to natural resources (natural and beneficial functions to floodplains) and human resources (life and property).”

(Federal Interagency Floodplain Management Task Force)

causes of floods
Causes of Floods

Estuarine interactions between stream-flow & tidal conditions

Combined rain & ice-melt

Coastal storm surges

Dam failures

Snow & ice-melt

Ice jams

Landslides

Rain

Earthquakes

Estuarine and Coastal Floods

Riverine Floods

Channel Factors

Basin factors (stable)

Basin factors (variable)

Drainage network factors

Estuary shape

Offshore gradient of water depth

Coastline configuration

Flood-Intensifying Factors

The Corps’ Technology Contribution

Possesses the capability to provide international assistance through training, the transfer of key technologies and direct support. Key areas relate to:

  • Remote Sensing and GIS:
    • Watershed delineation
    • Landuse characterization
    • Topographic and resource mapping
  • Hydraulic Engineering and Modeling:
    • River flow modeling
    • Flood inundation forecasting
    • Environmental enhancements for streams and rivers
    • Stream bank restoration and stabilization
  • Environmental and Water Quality Management:
    • Water quality assessments and pollutant loading analyses
    • Water quality monitoring
    • Watershed modeling
    • Invasive plant management
  • Water Resources Development:
    • Hydropower assessment, planning and design
sample corps international initiatives
Sample Corps International Initiatives
  • GIS training for Moldova
  • NATO-sponsored assessment of the Upper Tisza Basin (Eastern

Europe)

  • Proposed basin-wide study for the Niger River
  • Proposed development of a water control model for Lithuania
  • Proposed basin-wide study for the Nile River
  • Proposed development of an inundation model and workshop

for the Save and Limpopo Rivers
