Description Usage Arguments Details Value Author(s) Examples

A function demostrate an example series of steps to calibrate a reach in the SWAT2005 watershed model. This should act only as a simple demonstration, and should be modified to inidivduals use.

1	calib_swat_ex(flowgage, rch = 3)

`flowgage`	A list in the format that would be returned from the get_usgs_gage
`rch`	The reach in the output.rch file you wish to calibrate against.

This should act only as a simple demonstration, and should be modified to inidivduals use.

List (of length 2) containing the results of the internally called DEoptim function. See DEoptim for more information.
