Round 1

Reviewer 1 Report

Comments and Suggestions for Authors

In the manuscript, the chronological changes, cycles and influencing factors using M-K trend analysis, wavelet analysis, PMP test, were analyzed ,then quantified the role of precipitation and human activities in changes in sediment transport. It is important for water resources use in the basin, it has important results and can be accepted after minor revision.

Some comment:

In data sources:Annual precipitation and sediment load data from 1956 to 2020 were obtained from the hydrological data of HRB. Figure 2 give average monthly precipitation and sediment. Annual or monthly?

3.2 Anthropogenic factors:human activity?

3.2.2 Impact of changes in water use in a watershed on sediment load: the data are from 1984,why not from 1956. maybe some changes have been at the year before 1984.(figure 12:1965)

Why not analyse runoff’s impact on sediment?

The research Human activities have altered sediment transport in the Yihe River, the longest river originating from Shandong Province, China itself is very informative but needs comprehensive changes for further process.

 

• What makes your research novel? Could you provide a research gap from the body of existing literature for the introduction section?

• The section's final paragraph ought to discuss the paper's summary and scientific contributions.

• Figure 1 is not professional, the /m ... Should be (m), and KM....should be km.

• Could you please share the URLs to the data utilized in the section on data sources? 

• For better understanding, it is requested to change Figure 13 to a spatial pattern by using the interpolation technique.

• What I have observed, all the discussion section is already known, what are the new discussions from your research that are in in-line with the already published article? 

• There is a huge scope of conclusions and results illustrations. 

• I observed a lot of similarity ratios in your research. For instance, it cannot be more than 5% from a single source.

My final decision will be major revisions for further process.
