calculate_GW_inflow: Groundwater Inflow

In cvoter/isoH2Obudget: Lake Water Budget Using Stable Isotopes

Description

Calculates the groundwater inflow to a lake based on equation 4 in Krabbenhoft et al. (1990).

Usage

calculate_GW_inflow(
  P,
  E,
  d18O_pcpn,
  d18O_lake,
  d18O_GWin,
  d18O_evap,
  V = 0,
  d18O_lake_dt = 0
)

Arguments

P	precipitation (mm)
E	evapotranspiration (mm)
d18O_pcpn	d18O isotopic composition of precipitation
d18O_lake	d18O isotopic composition of the lake
d18O_GWin	d18O isotopic composition of groundwater inflow
d18O_evap	d18O isotopic composition of evaporation
V	volume of water in the lake
d18O_lake_dt	change in d18O_lake in over the timestep of interest (e.g., 1 month)

Value

GWin - the groundwtaer inflow to the lake (mm)
