lakeMaxDepth {lakemorpho}

Estimate maximum lake depth

Description

This function uses slope and distance to estimate max depth. This is based on the assumption that the slope of the surrounding topography is similar to the bathymetry of the lake (Hollister et. al 2011).

Usage

lakeMaxDepth(inLakeMorpho, slope_quant = 0.5, correctFactor = 1)

Arguments

inLakeMorpho

An object of lakeMorphoClass. Output of the lakeSurroundTopo function would be appropriate as input

slope_quant

The slope quantile to use to estimate maximum depth. Defaults to the median as described in (Hollister et. al, 2011).

correctFactor

Value used to correct the predicted maximum lake depth. Defaults to 1. Corrections are simply accomplished by multiplying estimated max depth by correction factor. Correction factors can be determined empirically by regressing the predicted depth against a known maximum depth while forcing the intercept through zero. The slope of the line would then be used as the correction factor(Hollister et. al, 2011).

Value

Returns a numeric value of the predicted maximum depth
