This cocument explains the list of files attached for SWAT-T.
## List of files
subroutine_modified: all the SWAT subroutines modified for SWAT-T, part of the subroutines are adpoted from Strauch and Volk 2013

add_SOS_sub_files.R: r script to add SOS months to existing SWAT project for SWAT-T

plant.dat: sample plant database

remove_mgtopt.R: r script to remove managment setings for trees, perenials and annuals

SWAT_rev627_smi_tropics: The SWAT-T executable release version. 

variables: this file contain all the new variables and arrays added to SWAT subroutines

window size: this file provides the number of days for aggregation for rainfall and PET  as well as the SMI threshold

### note for running 
1. Start by adding the SOS months for each subbasin in the project. If the catchment underconsideration is not large, meaning similar climatic condition across the sub-basins,
   then a single set of SOS months should be suffice. Otherwise, the SOS months can be varied across the sub-basins, this in principle should be for large basins.

2. remove the mangement setting for trees and perennials. If there is no managment operation in the natural ecosystem, remove all the default managment setting in the *.mgt files using the r-script
 
3. the default SMI threshold for season change is 0.5 with 5 days aggregation. 
These predefined thresholds can be adjusted (+/-), depending on the climatic condition of the catchment and perhaps the ecosystem type. 
In the current setup only one SMI and window size can be defined for the whole basin. 
The predefined SMI and window size can be provided by editting the window size ascii file and subsequently adding to the SWAT project files.
For anyone interested to set the SMI per land cover, the fortran sources codes requires a bit of adaption.

4. Now the SWAT-T is set to run :)
