Welcome to the SWAT-MODFLOW Google Group! Thank you for your interest in using the coupled SWAT-MODFLOW model. Preliminary information and documentation regarding the model can be found a the following website:

http://swat.tamu.edu/software/swat-modflow/

The download contains material recently presented at a SWAT conference workshop. The PowerPoint presentation outlines the SWAT-MODFLOW (and RT3D) linkage, and example files are provided in the accompanying folders. There is also a tutorial document that explains the HRU-Grid linkage in more detail.

Our team (Hendrik Rathjens, Katrin Bieger) currently is working on a Graphical User Interface that will automate the linkage process between SWAT and MODFLOW. We will keep you updated on its progress! We are expecting it to be released within the next few months.

Again, thanks for joining the group!
