levees Banks of sand and silt along stream bank built by deposition in small increments during successive floods.
limb The portions of a fold that are away from the hinge; the "sides" of the fold.
The levee vegetation was particularly poorly identified (Figure 5). Several factors may contribute to this: (1) narrow configuration - in many places, the levee was only as wide as a single tree canopy, ...

Natural Levee:
A mound of sediment that parallels a stream channel forming a levee-like deposit.
Commonly found behind levees. Backwash The return water flow of swash. This sheet of water flows back to ocean because of gravity. Bacteria Simple single celled prokaryotic organisms.
Use the unsteady flow routing features for dam break analysis and levee breaching.
Calculate water surface profiles based on steady, gradually varied flow for channel networks, dendritic systems, or a single river reach.
The loss of life and property damage was worsened by breaks in the levees that separate New Orleans, La., from surrounding Lake Pontchartrain and Lake Maurepas. At least 80 percent of New Orleans was under flood water on Aug.
levee Artificial bank confining a stream channel or limiting adjacent areas subject to flooding; an embankment bordering a submarine canyon or channel, usually occurring along the outer edge of a curve.
View 1 could be rainfall, View 2 flooded areas, View 3 damage to bridges or levees, View 4 other economic damage, all animated as a time series. A black border 2 pixels wide is drawn around each view.
Levees may be built to prevent flooding.
Sluice gates provide a means of controlling flow and adjusting river levels.
floodways may be added to draw off excess river water in times of flood.
from a storm, including thunderstorms, rapid melting of large amounts of snow, or rivers which swell from excess precipitation upstream and cause widespread damage to areas downstream, or less frequently the bursting of man-made dams or levees.
Emergency Preparedness: Relief agencies such as the Federal Emergency Management Agency (FEMA) will be able to use basic, standalone GPS receivers to map out geographical features such as flood plain boundaries, levees, ...
