LeveeFailures: Levee Failures along the Mississippi River

Description

Factors relating to Mississippi River levee failure

Arguments

Format

A data frame with 82 observations on the following 14 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

Constriction of the floodway over time (1880s to present)

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

Dredging

Dredging intensity

Revetement

Is there a stone structure (wall) meant to hold up the bank? (1=yes or 0=no)

Details

The goal of this investigation was to test the relative importance of geologic, geomorphic, and other physical factors that have led to levee failures through the past century along much of the Mississippi River.
