A Study on Factors Influencing Ground Subsidence and a Risk Analysis Method Using the Attributes of Sewer Pipes

Round 1

Reviewer 1 Report

The authors investigated the factors affecting ground subsidence and risk assessment using sewer pipe data. In general, the prediction accuracy is not high and this is understandable because the analysis relies heavily on the data obtained. Hence, it is important to ensure integrity and accuracy of the data. First, the method in data collection is not clear; the sample size, the location, and does the pipe data applies to the same batch of pipes or is it a collective data? Authors should also show samples of raw data and explain how the numbers (pipe age, diameter etc) were obtained. Second, the assumptions and limitations used in the analysis should be clearly stated, and the rationale in choosing these analysis method must be explained. Third, since no actual data is collected by the authors, the primary source(s) must be clearly stated. Is the data available to the public? Third, the application of the proposed solution may not be feasible before pipe data is adequately and accurately collected.

L46 - "facilities" should not be used to describe pipes.

L78 - CCTV should be spelt in full when first appear
