Water level, flow and quality: how to prepare the measurement point, the level reference and the sensor installation in rivers, wells and reservoirs.
In a study off the southern Baltic coast, a conductivity sensor moored at 2 m with a used TBT cell was out of specification at the first comparison after deployment, on day 32; with a UVC emitter, the last references, after 237 days, were within the margin. What this changes when planning visits and references.
A study in a Swiss apple orchard compared dendrometer-driven irrigation with irrigation driven by soil moisture sensors over two seasons: the dendrometer treatment used 38% less water in 2022 and more than 45% less in 2023, with no significant difference in yield. What it allows us to conclude, what it does not, and what it changes in deciding what to measure.
Five decisions for installing a water temperature logger in a river: compare the sensors, look for shade, look for moving water, plan for the level dropping and choose the interval. With the limits of each source.
The week in four signals and the tipping-bucket rain gauge guide, three European signals with their sources (Spain's warmest summer since at least 1869, Spanish reservoir storage and the new European Water Academy) and the close of the hydrological year on 30 September.
A tipping-bucket rain gauge loses rain to wind and to its own mechanics, and the second loss grows with intensity. What four peer-reviewed studies say about installation height, dynamic calibration and maintenance.
A study published in May 2026 calibrated low-cost capacitive sensors in the laboratory and then moved them to real plots. The laboratory curve drifted in the field, and a single reference measurement on site recovered much of the accuracy.
On 10 September, Copernicus published its August 2026 bulletins: exceptionally dry surface soils and river flows well below average across much of Europe. What those maps support deciding, and what they do not.
What to document about the site, level reference and installation before selecting a sensor.
