Factors relating to Mississippi River levee failure

Variables:

A data frame with 82 observations on the following 15 variables.

Failure

Did the levee fail? (1=yes or 0=no)

Year

Year

RiverMile

Location along the river (mile marker)

Sediments

Sediments present? (1=yes or 0=no)

BorrowPit

Borrow pit present? (1=yes or 0=no)

Meander

Type of meander (1=inside bend, 2=outside bend, 3=chute, 4=straight)

ChannelWidth

Width of the river channel (in meters)

FloodwayWidth

Width of floodway (in meters, levee to levee, levee to bluff, or bluff to bluff, as appropriate)

ConstrictionFactor

LandCover

1=open water, 2=grassy, 3=agricultural, 4=forest

VegWidth

Vegative buffer width (in meters)

Sinuosity

River length divided by valley length for 10 miles up- and down-valley from levee site
