Interactive comment on “Scalable Flood Level Trend Monitoring with Surveillance Cameras using a Deep Convolutional Neural Network” by

General comments: This paper proposed an approach to monitor flood level trend using DCNN. The topic is very interesting. However, in my opinion, it could be difficult for modelers, decision-makers and city planners to use the Static Observer Flooding Index (SOFI) directly. The authors should clearly explain what the direct or specific application scenarios of SOFI are. If SOFI or visible area of the flooding can be converted into water depth value or even class information on water depth, it would make
