Abstract

enFor a long time now, people have tried to understand, measure and characterize rivers. The water flow is an important parameter. In fact, it plays an essential role in the design of infrastructures but also in the protection of the population and the environment when extreme events occur. When the water flows are too high, traditional gauging methods are of no use. Besides, those methods are time-consuming and require specialized material which makes them expensive. In recent years, non-intrusive and contactless techniques have been developed and are of particular interest to the scientific community. However, those new techniques linking photogrammetry and hydraulics still involve a lot of adjustments to be completely functional. This work presents a comparison between photogrammetrical software, water surface detection methods based on 3D models and a database which allow a centralization of information collected on the field. The aim of this publication is to complete, improve and automate the method developed at UCLouvain over the past few years.
