An image with digital imaging tools that relate to hydrology.

The Riverflow 2016 conference had a full session on recent research in image-based measurements and video analysis. It is exciting to watch innovation in process as these researchers learn to exploit the capabilities of emerging consumer technologies. Never mind that the primary use of these technologies is so that people can instantly share their sense of place in the ‘real world’ within the virtual world...

An illustration of stage-discharge rating curves.

Almost everything we know about our global freshwater resources is due to the humble stage-discharge rating curve. The vast majority of all flow data ever produced is the derived result of a transform from a variable that is easy to monitor continuously (stage) to a variable that is impossible to directly measure continuously (discharge). This means we are dependent on rating curves for advancements in...

Water For Food, Global Water Withdrawals Graphic.

By 2050, a world population of 9 billion will require 60% more food. The security of our global food supply is highly reliant on adequate water supply. According to the United Nations, “agriculture is the biggest water user, with irrigation accounting for 70% of global water withdrawals.” While the global population is growing, water supply is not. So to meet 2050 food demands, it’s important...

Water monitoring training resources with large play button.

Water monitoring is a place-based activity. The work is wherever the water is, which is all over the planet. A stream hydrographer can cover a very large geographic area so regional offices typically only concentrate a small number of hydrographers at any one location and there are many locations. Water monitoring agencies have limited resources available to develop specialized training material or to send hydrographers...

An illustration for water news 2016.

Last month was a busy one for water news. The biggest story of the month has to be that 2015 was the hottest on record. This is true globally with the WMO reporting that 2015 broke all previous records by a strikingly wide margin at 0.76° C above the 1961-1990 average. This marks the first time that global temperatures have been 1° C above the...

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...
