In EcoHydRology: A Community Modeling Foundation for EcoHydrology

Description

An example objective function for calibrating SWAT2005 model.

Usage

swat_objective_function_rch(x, calib_range, calib_params, flowgage, rch, save_results = F)

Arguments

x	Numeric vector similar to change_params$current defining the scalar states of the parameters to be optimized.
calib_range	2 place vector of begin and end dates for calibration.
calib_params	Dataframe in the format of change_params limited to those rows of parameters desired to calibrate. See change_params.
flowgage	list of the format of the list returned by the function get_usgs_gage.
rch	Number of the reach in the output.rch file you desire to calibrate against
save_results	Logical to express if you want to copy the optimial solution to the current directory, overwriting the swat input files.

Value

abs\(NS - 1\) as needed to be able to minimize to optimal as needed for DEoptim function.
