On the basis of the comments from the Reviewers, a series of major concerns have emerged. From the totality of these, and considering the Authors' responses, I am willing to give the Authors the opportunity to submit a revised work. It should be clear that it is not my intention to discount any of the comments raised by the reviewers and that, in case the Reviewers are not fully satisfied, the manuscript will be unambiguously released.

While the reviewers are generally satisfied, the first Reviewer raises a few (very) minor technical issues (mostly related to grammar) and one technical point related to provide a clear distinction between surface irrigation (flooding) and surface & ground water sources used to supply irrigation water. I would encourage the Authors to take all of the points into account. Once this is accomplished, I will then be in a position to make a final decision.

While I do think the manuscript can be accepted at this stage, there are a few technical elements, related to the use of English, which should be carefully considered. For example, statements such as "Also, future refinement of the model would be served by measuring the salinity of irrigation source water. This would be more important if this model was implemented for irrigation that depends on groundwater sources, especially hydrologically closed basins" are somehow awkward in terms of wording. I am confident these issues will be resolved in this final segment of the process.
