A Critical Review on Water Level Measurement Techniques for Flood Mitigation

Flood related disasters have been the cause of millions of misplaced people and casualties worldwide. Hence it is necessary to develop monitoring systems capable of measuring water levels and depths by means of sensors or camera surveillance. Contact measurement sensors have disadvantages of regular maintenance and high operational costs, whereas camera surveillance combined with computer vision and image processing outweighs the advantages of the former measurement systems. In this study, traditional image processing and some more advanced and current state-of-the-art computer vision techniques have been compared and analyzed according to their implementation.
