Large Scale image-based flow velocimetry techniques experienced a huge development over the last years. The purpose of this work is to introduce a new affordable, practical and user-friendly toolbox (RIVeR) for Large Scale surface flow velocity analysis of streams such as rivers, channels but also large phys-ical models. The toolbox uses the results from conventional 2D Large Scale image-based flow velocimetry techniques (LSPIV - Eulerian frame of reference, and LSPTV - Lagrangian frame of reference ) ortho-rectifying them instead of ortho-rectifying the images first, which reduce dramatically the computational cost. RIVeR is fully operational and has been already used in many applications with extreme conditions such as streamgaug-ing during flash-flood events and low water level where available conventional techniques used are not able to measure.
