Remote Sensing, 2019 This paper describes a non-contact methodology for computing river discharge based on data collected from small Unmanned Aerial Systems (sUAS). The approach is complete in that both surface velocity and channel geometry are measured directly under field ...

Dealing with LSPIV questions on the field: An approach for autonomous flood gauging using UAVs
, 2020 In an era when flood phenomena intensify worldwide, the scarcity of proper and systematic flood flow measurements has become a conundrum. As an answer, the non-intrusive Large-Scale Particle Image Velocimetry (LSPIV) method has recently advanced to a contemporary gauging alternative, though several limitations in the field application pose questions ...

Application of LSPIV method to home movies for flood discharge estimation
, 2015 In the context of flash floods, or in ungauged basin, we propose to use the acquired video and posted online by witnesses. The preliminary work carried out since 2012 on this issue were used to develop and validate an image sequence processing methodology to overcome the difficulties related to the amateur nature of video capture : camera movements ...
