hydro_year_DGI: Hydrological year classification

In hydroToolkit: Hydrological Tools for Handling Hydro-Meteorological Data from Argentina and Chile

Description

This function allows you to get the hydrological year. The criteria is consistent with the one of Departamento General de Irrigacion (Mendoza - Argentina).

Usage

hydro_year_DGI(df)

Arguments

df	a data frame with total annual volumes discharges created with agg_serie function.

Value

A data frame containing the hydrological classification for each year.

Examples

# Create BDHI hydro-met station
guido <- create_hydroMet(class_name = 'BDHI')

# List with meteorological variables (slots in BDHI's object)
cargar <- list('precip', 'Qmd', 'Qmm')

# Now assign as names the files
hydro_files   <- list.files( system.file('extdata', package = "hydroToolkit"), pattern = 'Guido' )
names(cargar) <- hydro_files

# Build the object with the met records
guido <- build_hydroMet(obj = guido, slot_list = cargar, 
               path = system.file('extdata', package = "hydroToolkit") )
               
# Now get mean monthly discharge
Qmm <- get_hydroMet(obj = guido, name = 'Qmm')[[1]]

# Get the monthly water volume
Qmm_vol <- Qmm_to_Dm(df = Qmm)

# Aggregate data frame to get total annual discharges
AD  <- agg_serie(df = Qmm_vol, fun = 'sum', period = 'annual', out_name = 'Ann_vol',
         start_month = 7, end_month = 6, allow_NA = 2)
         
# Get hydrological year classification
AD_class <- hydro_year_DGI(df = AD)
