summarise_dV: Monthly Change in Lake Volume

In cvoter/isoH2Obudget: Lake Water Budget Using Stable Isotopes

Description

Calculates the monthly change in lake volume based on daily lake levels and an elevation-volume relationship from bathymetry analysis.

Usage

summarise_dV(lake_levels, timeseries)

Arguments

lake_levels	a data frame with daily water level measurements as formatted in the lake_levels dataset, subset to lake level records for the lake of interest.
timeseries	a list with dates (POSIXct) to analyze, and intervals (lubridate interval) covering the month before each analysis date.

Value

monthly_dV, a data frame with the following columns:

date

first of the month for each monthly observation

dV

change in lake volume during the month (m^3)

mean_vol_m3

mean lake volume during the month (m^3)

mean_area_m2

mean lake surface area during the month (m^2)
