In tsamsonov/grwat: River Hydrograph Separation and Analysis

Set the value of hydrograph separation parameter

Description

The value is set for selected years in parameter list. Such list is returned by gr_separate() with debug = TRUE set.

Usage

gr_set_param(params, p, value, years = NULL)

Arguments

params	list of lists of hydrograph separation parameters as returned in params attribute by gr_separate() with debug = TRUE.
p	Name of the parameter.
value	Numeric value to set.
years	Integer vector of years to modify. Defaults to NULL, which means that all years will be modified.

Value

list of lists — a modified version of params

Examples

library(grwat)

data(spas) # example Spas-Zagorye data is included with grwat package

# Debug mode gives access to additional information
sep = gr_separate(spas, 
                  params = gr_get_params(reg = 'center'), 
                  debug = TRUE)

# Visualize
gr_plot_sep(sep, c(1978, 1989)) 

# actual params used for each year
parlist = attributes(sep)$params

# set the sprecdays parameter for multiple years
parlist = gr_set_param(parlist, sprecdays, 
                       years = c(1978, 1989:1995), 
                       value = 15)

# use the list of parameters for separation
sep_new = gr_separate(spas, params = parlist, debug = TRUE)

# Visualize
gr_plot_sep(sep_new, c(1978, 1989))
