SWAT
SWAT-CUP is a computer program for calibration of SWAT models. SWAT-CUP is a public domain program, and as such may be used and copied freely. The program links GLUE, ParaSol, SUFI2, MCMC, and PSO procedures to SWAT. It enables sensitivity analysis, calibration, validation, and uncertainty analysis of a SWAT model. The overall program structure is as shown in the Figure below.
In the new version, SWATCUP_4.3.1, a more powerful SWAT_Edit program is provided where ALL SWAT parameters are handled, including different soil layers and management rotation-operations, precipitation data, etc. The users are also allowed 20 “free” parameters placed at the end of *.gw files to use for their own programs, which may be linked to SWAT. This version also includes parallel processing (which is licensed but 20 simulation are allowed to be made for testing the program), visualization of the outlet locations using the Bing Map, creation of multi_objective objective function, extraction and calculation of 95PPU for all variables in output.rch, output.hru, and output.sub files without measurements, and one-at-a-time sensitivity analysis).
Upcoming functionalities of SWAT-CUP would include visualization of calibrated variables superimposed on Bing Map, as well as ArcSWAT's river map, and subbasins.
