swat_objective_function_rch {EcoHydRology} | R Documentation |
An example objective function for calibrating SWAT2005 model.
swat_objective_function_rch(x, calib_range, calib_params, flowgage, rch, save_results = F)
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. |
abs\(NS - 1\) as needed to be able to minimize to optimal as needed for DEoptim function.
