vertmean: Vertical Means of Water Bodies (Lakes and Reservoirs)

In rsachse/limnotools: Help Tools of TU Dresden's Limnology Workgroup

Description

Calculate vertical mean values which respect different depths of layers and lake morphometry.

Usage

vertmean(depth, vari, level, top, bot, vol)

Arguments

depth	sorted vector of sampled depths
vari	measurements corresponding to depth (concentration, temperature, ...)
level	Surface water level (above ground or m NN, depending on hypsographic function used
top	top water level of requested layer
bot	bottom water level of requested layer
vol	hypsographic function to be used (e.g. vol.depth)

Value

volumetric average value of the requested layer between depths top and bottom.

See Also

vol.tsb, vol.depth

Examples

## Plot of hypsographic function
plot(x<-seq(0,155,0.01),y<-vol.tsb(0,x),xlim=c(154,max(x)))

## Test Data
level <- 167.5

depth <- c(0, 1, 6, 7, 8, 9, 10, 11)
vari  <- c(18.8, 17, 12.1, 11.9, 11.8, 11.7, 11.4, 11.4)

vertmean(depth, vari, level, top=0, bot=4, vol.depth)
vertmean(depth, vari, level, top=4, bot=13.5, vol.depth)

vertmean(depth, vari, level, top=0, bot=4, vol.tsb)
vertmean(depth, vari, level, top=4, bot=13.5, vol.tsb)

vertmean(depth, vari, level, top=0, bot=3.7, vol.depth)
vertmean(depth, vari, level, top=3.7, bot=13.5, vol.depth)

vertmean(depth, vari, level, top=0, bot=3.7, vol.tsb)
vertmean(depth, vari, level, top=3.7, bot=13.5, vol.tsb)
