lakeMeanDepth {lakemorpho}

Function to return lake Mean Depth

Description

Calculates average depth of lake as a mean of lake volume divided by lake surface area

Usage

lakeMeanDepth(inLakeMorpho, zmax = NULL, slope_quant = 0.5, correctFactor = 1)

Arguments

inLakeMorpho

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

zmax

Maximum depth of the lake. If none entered and elevation dataset is inlcuded in inLakeMorpho, lakeMaxDepth is used to estimate a maximum depth.

slope_quant

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

correctFactor

This a factor used by lakeMaxDepth to correct the predicted maximum lake depth. Defaults to 1.

Value

Returns a numerica value for the mean depth of the lake
