Dam Siting: A Review
Round 1
Reviewer 1 Report
Dear authors,
The present paper aims to highlight the factors that condition the selection of the appropriate location for the construction of dams and the most appropriate siting methods. Hydrological, geological, topographical, water quality, environmental, socio-economic factors and parameters are covered in a convincing way.
It is an interesting work and potentially publishable, with obvious practical implications in water resource management.
I recommend publication of this work with some minor considerations.
In my opinion, there are some aspects that could be revised, so that the manuscript should be more consistent.
I do not consider relevant the aspects related to mentioning the databases used to find in literature the issues of the location of the dams or of the journals in which the publication was made. Thus, I suggest giving up subsection 2: Investigation and Analysis of Related Literature.
Regarding the part on the use of remote sensing and GIS, references regarding the applicability of UAV photogrammetry and 3D mapping (3D surface models) could be added. The DEMs generated from the images taken from the drones have high resolution and can be used successfully to determine the most suitable location of the dams using topographic constraints. The digital elevation model represent an input to calculate the drainage model.
As for the bibliography, not all references follow exactly the editing rules contained in the author's guide.
I encourage the authors to work to improve their manuscript.
