conv_WL: converts cm of water above the logger to water level relative to surface

Description

This function converts cm of water above the logger to water level relative to the surface of the weltand. For this function to work, you must have a field named: SITECODE_cm. To get this field, should either run the conv_kpa_cm() function first, or calculate cm of water for that site by hand. The SITECODE also needs to be defined in the function arguments.

Usage

conv_WL(df, cm_water, ground, corfac)

Arguments

df	data frame with pressure data
cm_water	Quoted field name containing cm of water above logger
ground	numeric distance between the logger and the surface of the wetland (Logger Length + Measuring Point to Bold - Stick Up Height).
corfac	numeric correction factor (in cm) to correct for difference in atmospheric pressure due to differing elevations between where the water level loggers are and where the atmospheric pressure loggers are.

Value

Returns a data frame with a new column labeled with SITECODE_WL, which is the water level in cm relative to the surface of the wetland. Negative values are below ground, positive are above ground.

Examples

## Not run: 
df <- data.frame(BIGH_AbsPres = c(110.1, 111.3, 110.4), WMTN_BARO_AbsPres = c(102.1, 103.1, 102.8))
df <- conv_kpa_cm(df, pres = 'BIGH_AbsPres', baro = 'WMTN_BARO_AbsPres')
df <- conv_WL(df, cm_water = 'BIGH_cm', ground = 88.9, cor = 5.004)

## End(Not run)
