hydrogeo.p-atmosphere: Elevation pressure and head.

In abarbour/hydrogeo: Tools for hydrogeology and poroelasticity

Description

A collection of functions to deal with atmospheric pressure and head calculations.

Usage

atmos_p(pressure.units = c("hpa", "bar"))

atmos_head(elev.m = 0)

m_per_hpa(elev.m = 0)

hpa2m(hpa = 0, elev.m = 0)

elev2hpa(elev = 0, elev.units = c("m", "ft"))

Arguments

pressure.units	character; the units of atmospheric pressure
elev.m	numeric; the elevation, in meters
hpa	numeric; pressure in hecto-Pascals
elev	numeric; the elevation
elev.units	character; the units of elevation associated with elev

Details

atmos_p returns atmospheric pressure in the units of meters or feet.

atmos_head calculates the amount of head of water produced by atmospheric pressure for a given elevation.

m_per_hpa calculates the expected scaling between water level (head) and pressure for a given elevation.

hpa2m calculates the water level (head) for a given pressure and elevation.

elev2hpa calculates the expected RMS tropospheric pressure head, by correcting sea level at STP for lapse effects.

Value

numeric
