Flood Plain:
An area of alluvium-covered, relatively level land along the banks of a stream that is covered with water when the stream leaves its channel during a time of high flow.
Flood Stage: ...
This paper outlines a GIS approach to modelling laterla instability in river channels as a means of risk assessment in flood plain management.
Is the building located on a site (bottom of hill, flood plain) prone to natural disasters?
b. Have records been lost to a disaster in the past? Describe
c. Are basic emergency supplies on hand?
First, don't build on flood plains or earthquake faults. These are best kept for parks, or perhaps unimproved farmland. In any case, limit capital improvements. Some of the most beautiful cities, such as San Antonio, use this principle.
The data fusion would be ideal for flood mapping (before and after) by accurately mapping the flood plains and identifying structures that are in the flood plain. This data can be used in modeling the extent of flooding using storm surge modeling.
flood control map See: map, flood control flood plain Belt of low flat ground bordering a stream channel that is flooded when runoff exceeds the capacity of the stream channel.
Which properties lie on or next to a flood plain?
Which tracts have direct access to a highway? To a lake?
Which species have habitats in contact with a protected ecological region?
Cities have often grown onto coastal and flood plains at risk of floods and storm surges. Urban planners must consider these threats.
overbank deposits Sediments deposited from flood water on the flood plain.
overturned fold An inclined fold in which one limb has been tilted beyond the vertical, so that the stratigraphic sequence within it is reversed. compare inclined fold.
Although the exact set of factors to be considered may change in different parts of the country, most transmission line routing requires attention to environmental (e.g., wetlands and flood plains), community (e.g.
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, ...
