| General Comments: | The authors identify four different SWAT models in their study: SWAT-EP, SWAT-PS, SWAT-CN and SWAT-P. SWAT-EP is the key version which features new modifications they introduce to more accurately simulate rice paddy hydrologic functions. SWAT-CN and SWAT-P are both applications of the standard SWAT model, which represent typical applications that rely on adjustments of the runoff curve number (SWAT-CN) or an application that incorporates the use of the pothole routine in the standard SWAT code (SWAT-P). The SWAT-PS version incorporates code modifications that were first described in the following previous study: Sakaguchi, A., S. Eguchi, T. Kato, M. Kasuya, K. Ono, A. Miyata and N. Tase. 2014.
