Authors’ response: Thanks for caching this error, the sentence has been corrected.


3- affects is the right word.
Authors’ response: Authors agree, this mistake has been corrected.


4- The sentence seems complex. It can be broken into simpler sentences for better understanding.
Authors’ response: Thank you for this suggestion. This sentence was changed as suggested to improve clarity.


5- Which technique?
Authors’ response: This sentence has been edited for better understanding.


6- as a guide
Authors’ response: Thanks for caching this mistake. It has been changed in text.


7- State the datum or reference. Is this elevation from mean sea level or anything else?
Authors’ response: This elevation from mean sea level based on digital elevation model (DEM) results.


8- It's sub-watershed not sbu watershed.
Authors’ response: Thank you for pointing out this mistake. It has been corrected.


9- Provide reference for this data.
Authors’ response: The reference for this data has already been given in the Table 1.


10- Discuss the vertical and horizontal accuracy of the DEM used in the study.
Authors’ response: The vertical and horizontal accuracy of the DEM used in the study has been added.


11- The details of data sources given in this table is appreciable. Thank you for providing the source of data in such manner.
Authors’ response: The authors thank the reviewer for his kind words.


12- Detached
Authors’ response: Thanks for caching this mistake. It has been corrected.


13- Provide equation number properly.
Authors’ response: The equation number has been provided properly.

Authors’ response: Thanks for caching this mistake. It has been corrected.


15- Fig. 1 (better figure can be provided in better resolution if available)
Authors’ response: Thank you much. Please, the resolution of all maps (raster) produced in this analysis is 30ï‚´30 m, the same as the digital elevation model. Most of the maps are derived from more coarse resolution and resample to be agree with 30ï‚´30 m. Accordingly, we would appreciate the respectable reviewer accepting our figures since we did our best with the available data.


16- Fig. 2 (No need to provide boundary on legend as it is colliding in the figure)
Authors’ response: Thank you. We believe that the boundary of a legend is necessary to separate the other parts of the map from the main figure.


17- Fig. 3 and Fig. 4 (this map is not buffered properly in ArcGIS it can be improved at the edges for better appearance.
Authors’ response: Many thanks for the respect reviewer; both figures were redrawn to meet the reviewer comment. Please, see these figures in the revised version of the manuscript.

 

Reviewer 2 Report

This paper deals with the prediction of soil loss rate in a transboundary watershed in Iraq, coupling the RUSLE model and GIS.

Add remote sensing as keyword.

Watersheds are globally facing significant environmental challenge. Replace the word watershed with landscape. The watershed is a hydrological term and do not face challenges, The management of watershed is a challenging task. Please correct it is no easy to follow in the current form.

Erosion has a negative influence on the sustainability and productivity of agricultural areas…as well as biodiversity (https://doi.org/10.3390/su14052738, https://doi.org/10.1111/geb.12782

For instance, soil erosion models such as….also include the widely applied Gavrilovic model (EPM) https://scibulcom.net/en/article/RudumPyvp1Dc9aCFph69 . To that end, automated workflows have been developed in GIS environment.

A better description of the data source must be given. What’s the difference between the C factor and the LULC? Why both data used. Moreover, what about the P-factor of RUSLE model.

The spatial distribution of the meteorological station within the study area must be given.

Also, a detailed estimation of the K factor can be performed using the SoilGrids (https://soilgrids.org/) data based on the original formulas rather than simplified methods. Why the authors used this approach, please justify.

Therefore, in this study, the Global Rainfall Erosivity Da-
tabase (GloREDa). So the esdac database must be added to the table 1 (instead of meteorological data).

Which is the reference year for the Global Rainfall Erosivity Database? All the staton operates for a common period so as to have homogenized results?

Figure 3. Increase the fonts of the legend.

In general the approach is interesting and the subject important for the journal’s readers. However, the literature about the importance of soil loss and the existing models must be enlarged. Also, the selection of the databases must be justified and a better description is considered necessary. After all, I suggest major revision before publishing.

Response to Reviewers

1- Add remote sensing as keyword.
Authors’ response: Thank you for this suggestion. These words were added as keyword.


2- Watersheds are globally facing significant environmental challenge. Replace the word watershed with landscape. The watershed is a hydrological term and do not face challenges, The management of watershed is a challenging task. Please correct it is no easy to follow in the current form.

Authors’ response: Thank you much. As suggested by the reviewer, the word ‘’ landscape’’ used instead of ‘’watershed’’


3- Erosion has a negative influence on the sustainability and productivity of agricultural areas…as well as biodiversity (https://doi.org/10.3390/su14052738, https://doi.org/10.1111/geb.12782
Authors’ response: we agreed there is another impact of soil erosion on biodiversity.


4- For instance, soil erosion models such as….also include the widely applied Gavrilovic model (EPM) https://scibulcom.net/en/article/RudumPyvp1Dc9aCFph69 . To that end, automated workflows have been developed in GIS environment.
Authors’ response: Thank you so much, we totally agree with your opinion there are many models have been applied to predict soil erosion, in the current study we mentioned some of them as examples.


5- A better description of the data source must be given. What’s the difference between the C factor and the LULC? Why both data used. Moreover, what about the P-factor of RUSLE model.
Authors’ response: Thank you so much; Table (1) is enhanced to better description of the data source, please, see Table (1) for more details.
Soil crop management refers to the practices that are carried out in order to maintain and improve the health and productivity of the soil in which crops are grown. These practices may include activities such as fertilization, irrigation, soil erosion control, and pest management. Land use refers to the way in which land is used or exploited by humans. Land use can include activities such as agriculture, forestry, urban development, and recreation. Land cover refers to the physical material that covers the land surface, such as vegetation, water bodies, and built structures. Land cover can be affected by land use, as land use activities can change the natural land cover.
From the above definitions, there is a clear difference between these terms as the soil crop management (C) factor is a number that can be easily assigned in the RUSLE equation and
indicates how the conservation plan will contribute to soil loss and how that soil loss might be distributed over time.
(Moreover, what about the P-factor of RUSLE model)
Kindly please, there is a single paragraph in the manuscript (section 3.5) about how we assigned this factor. Please, see page 8 in the revised manuscript for more details.


6- The spatial distribution of the meteorological station within the study area must be given.
Authors’ response: We thank the reviewer for pointing out this, the meteorological station has been added as shown in Figure 1.


7- Also, a detailed estimation of the K factor can be performed using the SoilGrids (https://soilgrids.org/) data based on the original formulas rather than simplified methods. Why the authors used this approach, please justify.
Authors’ response: Kindly please, FAO's global soil map uses the same empirical equations to estimate K factor and does not use simplified methods. Therefore, our calculations were based on these data.


8- Therefore, in this study, the Global Rainfall Erosivity Database (GloREDa). So the esdac database must be added to the table 1 (instead of meteorological data).
Authors’ response: Thank you so much for this valuable comment. The reference was corrected in the Table (1) in the revised manuscript.


9- Which is the reference year for the Global Rainfall Erosivity Database? All the station operates for a common period so as to have homogenized results?
Authors’ response: The year of this map is 2017 and it is added to the manuscript in the section 3.1 (in red color).


10- Figure 3. Increase the fonts of the legend.
Authors’ response: Many thanks for the respect reviewer; the figure was redrawn to meet the reviewer comment. Please, see this figure in the revised version of the manuscript.


11- In general the approach is interesting and the subject important for the journal’s readers. However, the literature about the importance of soil loss and the existing models must be enlarged. Also, the selection of the databases must be justified and a better description is considered necessary. After all, I suggest major revision before publishing.
Authors’ response: Thank you for your comments and suggestions. We appreciate the time you spent reviewing our manuscript and the insight you provide in helping us strengthen the presentation of our work.
