Einstein headshot with Aristotle quote.

The most passionate people involved in the water monitoring industry all care deeply about the preservation of traceable provenance for their data. To people on the outside this can seem like an indulgence that adds a burden of work to the data management process with little apparent benefit. The benefit is ‘verifiable truth’, a distinction with little value. Until it matters!...

Magnifying glass on a Dodo bird, an extinct species.

I have been playing around with Paul Whitfield and Jennifer Dierauer’s Flowscreen R package designed for detecting trends and changepoints in hydrological time series and it got me thinking about how time series data analysis may be becoming an endangered activity. The immediate priority for any monitoring agency is to provide data for urgent requirements. Real-time data dissemination is king. You need to go well...

An image showing drones for hydrometry.

A different point of view changes nothing but it can change everything. Last week I wrote about how unmanned Aerial Vehicles (UAV), also known as drones, could be used for Large Scale Particle image Velocimetry (LSPIV) to get surface velocity measurements, which when combined with surveyed cross-sections can produce extreme flow gaugings. That same drone, equipped with the same camera, can also provide the cross-sectional...

2016 challenges and opportunities in hydrometry graphic.

Incremental change is an insidious thing. Like a frog in a pot of water on the stove it can be difficult to know what is going on when your attention is moment-to-moment. It could be that from day-to-day there is no noticeable change but year-to-year there is major change and decade-to-decade there is transformative change. The business of water monitoring is vastly different than when...

Two moons hanging over the earth.

The spacecraft New Horizons is on schedule to get a good view of Pluto on July 14th 2015. We should soon have some measurements that will help determine how much of the icy planet is made up of water. On board New Horizons are instruments like Ralph, Alice, Rex, and Lorri. The requirements for these devices are that they need to be small, lightweight, powerful and...
