Round 1

Reviewer 1 Report

General comments

The paper presents a very detail investigation on two grass species, especially on the function of preventing erosion based on root mechanical properties. The authors provided valuable test data from the rigorous test procedures and analyses. The results are well discussed and reach a clear conclusion. However, the conclusion of C. dactylon better than E. ophiuroides is only applicable to the test conditions set by the authors. A limitation on the conclusion should be added in the abstract and text.

 

Specific comments

  1. Line 86, “A pilot research…”. It the pilot research conducted by the authors or cited from other reference? Please specify it in the text.
  2. Line 98, “dry mass” should be dry unit weight.
  3. Line 67 “1. Sample Preparation” should be “1 Sample Preparation”. Please revise the numbering of title in section 2.
  4. Line 127, the font of ρ is not consistent with that in Eq. (3). Please revise it.
  5. Line 203. The test is done on a surface slope of 15 degree. Please explain the reason of picking up this angle. Is it supported by any on-site survey result?
  6. Line 216-222. The numbering of table is wrong. Please check it.

Reviewer 2 Report

Dear Editor,

As can be seen in teh first sentence of teh abstract teh paper need ful scientific editing. Besides, the abstract and Introduction need to follow standars in the sence they must identify research gaps, not only by staing that this type of research question has not been investigated in China. This is an international journal and issues have to be assessed on an international basis. I concur with all the other remarks by the reviewers.

I thus call for major revision

Reviewer 3 Report

This manuscript contains valuable content that contributes to the elucidation of soil, water and plant interactions. However, the reviewer believes that appropriate revisions by the authors are necessary for publication as a journal article, as stated in the following comments.

(1) The abstract is redundant. The authors should devise a way to summarize the contents of the manuscript.
(2) The amount of introduction is small, and the novelty and originality of this research cannot be found.
(3) Instead of the Introduction, a new Section 2 should be established to describe related research results.
(4) In the figure, color is desired instead of monochrome.
(5) The amount of Conclusions is small, that is, the reviewer doubt that this manuscript will not produce much results.

Reviewer 4 Report

This manuscript describes erosion controls of two C4 grass species in Taiwan. The authors measured root area ratio, root traits, maximum pullout resistance, root diameter, tensile resistance force, tensile strength, soil loss, and relative soil detachment rates to evaluate erosion control of C. dactyhon and E. ophiuroides.  I think the results of this study will be useful to readers. So, I recommend that this manuscript is qualified to be published in Water journal after the revision.

Minor comments

  1. in Section 2.1, add relevant references for sample preparation.
  2. in line 101, add relevant equation and notation regarding maximum pullout resistance, Fmax, and N.
