Better prediction and monitoring of flood events are key factors contributing to the reduction
of their impact on local communities and infrastructure assets. Flood management involves …

Enhanced and effective hydrological monitoring plays a crucial role in understanding water-
related processes in a rapidly changing world. Within this context, image-based river …

Image velocimetry has proven to be a promising technique for monitoring river flows using
remotely operated platforms such as Unmanned Aerial Systems (UAS). However, the …

An automatic workflow to measure surface flow velocities in rivers is introduced, including a
Python tool. The method is based on particle-tracking velocimetry (PTV) and comprises an …

Large-scale image velocimetry is a novel approach for non-contact remote sensing of flow in
rivers. Research within this topic has largely focussed on develo** specific aspects of the …

Since the turn of the 21st Century, image based velocimetry techniques have become an
increasingly popular approach for determining open-channel flow in a range of hydrological …

The scarcity of water can result in a direct conflict between the protection of aquatic
resources and water use. For many agencies, environmental flow (EF) methods are …

Streamflow data is often the most critical input for hydrologic and hydraulic research,
modeling, and design studies. Streamflow measurement using close range non‐contact …

This paper describes a novel velocimetry method we call infrared quantitative image
velocimetry (IR‐QIV), that uses infrared (IR) images of thermal patterns advecting on water …

Because digital image data acquisition has become low cost and various image analysis
tools have become available, the number of image‐based measurement applications is …
