Development of Aerial Space Time Volume Velocimetry for Measuring Surface Velocity Vector Distribution from UAV

E3S Web of Conferences, 2018
Due to the remarkable development of unmanned aerial vehicle (UAV) in recent years, its application in river engineering increases widely mainly for the measurement of ground topography such as by the technique Structure from Motion (SfM) using a series ...

sUAS-Based Remote Sensing of River Discharge Using Thermal Particle Image Velocimetry and Bathymetric Lidar

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 ...

2DH modelling of a reservoir flushing compared with LSPIV measurements

, 2011
A reservoir flushing was completed on September 2008 in the Longefan reservoir (Arc en Maurienne River, France). This reservoir (approximately 300m×500m) is part of the EDF (French Electricity company) hydropower system. It is mainly used for the sedimentation of the water released from the upstream hydropower plant and for temporary storage for the ...

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 ...

Flow patterns in shallow rectangular reservoirs with open channel inlet or pipe flow inlet at various depths: An experimental study

International Journal of Sediment Research
This study experimentally assesses the influence of varying the inlet boundary condition on the flow patterns in rectangular shallow reservoirs. Two types of inlet boundary conditions were compared: a free surface inlet channel, and a pressurized ...
