Women in Water, Week 3: Onwards and Upwards

For the final week in our Women in Water series, started on International Women’s Day, we are interviewing women across the world who are dedicated to the protection of the water and the environment, and the use of technology to do so. This week, we met with Tamara Roberts, a Linko user at the City of Bloomington Utilities in Bloomington, IN, USA, and Angela Perks, an AQUARIUS user from the Bay of Plenty Regional Council in New Zealand.

Women in Water, Week 2: Making a Difference

As part of our Women in Water series, started on International Women’s Day, we are interviewing women across the world who are dedicated to the protection of the water and the environment, and the use of technology to do so. This week, we met with Kirsten Adams, an AQUARIUS user at the Department of Primary Industries, Parks, Water and Environment (DPIPWE), and Lynn Landry, a WaterTrax user at Metro Vancouver.

This week, we met with Donna Hollis, an AQUARIUS user from TasWater, and Alice Ohrtmann, a Linko user from Rock River Water Reclamation District.

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 – 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.
