Responses of Baseflow to Ecological Construction and Climate Change in Different Geomorphological Types in The Middle Yellow River, China
Round 1
Reviewer 1 Report
The paper is very interesting, brings some new information so in my opinion there is a neccessary novelty in the manuscript. The course of estimation, results and conclusions are shown properly and fully desribed. Text needs some editting corrections shown in attachted pdf file. After minor corrections I can recommend the paper to be published.

Reviewer 2 Report
The authors presented the response of the baseflow to ecological constructions and climate change. The paper organized well and the methods used also well presented. Appreciating the overall works, I would like to forward the following comments.
In recent years, the study of runoff in the region has mainly focused on water and sediment change [13]. If you want to show the trend/ focus of studies in recent years in the area, you need to put more citations. The authors mentioned the streamflow as watershed runoff, surface runoff, river runoff, and runoff (lines 9, 14, 37 …) in the paper. The term watershed runoff and surface runoff indicate the direct runoff (without baseflow). Therefore, the words describing the streamflow and direct runoff should be clearly identified. It is known that the construction of the terrace and check dam facilitates surface water infiltration by reducing water flow velocity. This could increase the groundwater recharge, which in turn increase the groundwater level and base flow to the river. But the authors found that one of the reasons for the reduction of the base flow is the construction of ecological structures (terrace and check dam). This should be checked again and/or should be justified. The reason for reduced baseflow could be mostly due to the availability of low precipitation and its loss in the form of evapotranspiration as a result of the increased vegetation coverage. It is also very important to check the sensitivity of the response of the reduction in baseflow to the ecological conservation factors (re-vegetation, check dam and terraces).
