Hydrometry Hydrology Next Generation

Hydrometry & Hydrology – The Next Generation

At Aquatic Informatics we are encouraged to take an active role in the community and so I was quick to agree when I was recently asked do a short course on hydrology for a conference on Global Stewardship at a local private school. It turned out to be a lot of fun, for me at least. I took a look on a map and realized that because the school is located at the crest of a hill and on the edge of a large forested park it provided an excellent opportunity to do a comparison and contrast between forest and urban hydrology. There is a lovely stream running through the forest, which provided an excellent contrast to an adjacent stream course that has been completely built over with housing.

Water Data Truth

Internet Truth vs Verifiable Truth – The Importance of Traceable Provenance in Water Information

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!

Is Time-Series Data Analysis an Endangered Activity?

Is Time Series Data Analysis an Endangered Activity?

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 down the list of urgencies before you come to the requirements of future generations of hydrologists who have not yet been born.

Drones Hydrometry Perspective - Hydrology Corner Blog

Drones – Providing a New Perspective on 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 information needed to complete the job.

2016 Challenges & Opportunities in Hydrometry

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 I was in the field.
