Monitoring small streams is not as easy as it seems
One issue is the growing number of climate-related extreme weather events. Another is the fact that these waterways are essential for mountain regions, and demand for monitoring equipment is increasing, especially during heavy rainfall. Various solutions exist for measuring the flow rate of small streams, but none are without their drawbacks: satellite imaging, for example, does not allow for adequate temporal and spatial sampling (generally once a week) and cannot generate alerts. Moreover, it requires direct human intervention, large quantities of equipment, and a complex procedure. For their part, industrial solutions for automated gauging (such as flowmeters, pressure valves or weirs) use reinforced installations (canalized waterways) but these are not environmentally-sound solutions suited to general deployment. Partial solutions such as radar certainly generate alerts in the event of floods, but these systems only offer a single measurement point, i.e., the water height; there is no way to directly estimate the flow rate (velocity needed) and this cannot account for variations in the width of the waterway. Lastly, imaging systems are primarily designed for large waterways and require large-scale installations, making them more expensive as a result..
