Complex Monitoring of Vertical Land Motions Corresponding to Geological Structure of Coastal and River Areas in Northwestern Poland
Round 1
Reviewer 1 Report
Dear authors,
Overall, the manuscript is of good quality and structure and clearly written. However, the discussion and conclusion are partly incomplete without an explanation of the causes for the displacements. Thus, a simple correlation of the results with the geological structure of the terrain can be added (at least brief considerations from available research). Also, a critical view of the used methodology missing (for example when compared with InSAR). There is a technical error in line 239 (combi-nations).

Reviewer 2 Report
The work is devoted to the description of the approach to the integrated monitoring of the vertical movement of geological formations in North-Eastern Poland. The authors have collected a huge amount of data describing such movements in specific areas. A distinctive feature of this study is the linking of observational data with the geology of the underlying structures.
I believe that the work will be interesting, at least due to the presentation of unique data collected by the authors and their conclusions about the features of the vertical movement of a number of structures in North-Eastern Poland, which must be taken into account when performing construction work.
I recommend the work for publication.

Reviewer 3 Report
The manuscript reports the comprehensive study of vertical land motions related to geological structure in North Western Poland. Detailed study on the height changes of benchmarks is presented followed by GNSS 3D measurements. The results reported represent a notable advance in the understanding of complex monitoring of vertical land motions in coastal areas.
The title and abstract are appropriate for the content of the text. Furthermore, the manuscript is well constructed and analyses are well performed. In abstract, the authors summarized the main research question and key findings. The description of study subject and results are detailed and correct.
This manuscript reads well, the figures are clear and readable and support the findings, but need improvments. The reference list needs to be completed. The research is interesting and my main concerns are the lack of some justifications in data interpretation. All the remarks are also listed in comments in PDF:
Lines 14-15: Layers refer to sedimentary rocks which are common for the Earth crust, so "Earth crust" should be deleted. It should be indicated the type of rock to which this layer refer to.
Line 42: In figure 1 it is not clear the position of research area within the Poland. The map of Poland indicating the exact position of Szczecin area is necessary.
Line 75: According to map it may be concluded that the study area lies on Permian-Mezosoic deposits. Please provide data regarding this unit. The authors start the geological setting with Upper Cretaceous unit, what about the older underlying rocks? In figure 5 is also presented the Mesozoic basement. What about the mentioned Permian?
Line 139: Correct the spelling of "sands and gravels" in a legend. It should be indicated the age of these deposits which are also mentioned in lines 82-86.
Line 197: Correct the spelling of "Mesozoic" and “organic soils".
Line 199: To what the "unstable geological structure" refers to? As it can been seen in figure 5 the only difference in a cross section is a presence of organic soils in Miedzyodrze area. How these deposits affect the unstability of this area?
Line 254: This chapter should discuss and explain the difference in vertical movements of benchmarks, especially in the area of Miedzyodrze.
Line 301: The Refernce list may be expanded by related topic papers published in MDPI journals.
