Hydrology Corner Blog

Hydrology Corner is a place for water industry experts to read and discuss best practices. This forum allows you an opportunity to voice your opinions about what can and should be done to build toward a desired future where decisions concerning water are well informed by adequate data.

Virtual Observatories and Snakes in the Grass

I ended my last post “Amazing GRACE” with a segue to virtual observatories with a call to “… start thinking about our methods of measurement and data management to figure how to combine what remote sensing does well (extensive coverage) with what field observations do well (high resolution).” Virtual observatories are a blend of the…

Is Rock Snot Affecting Your Rating Curve?

Didymo is a northern circumpolar species preferring cold, clear water. It is spreading rapidly with the primary mode of dispersion suspected to be contaminated fishing/wading gear. It is a problematic invasive species because it’s effect on the food web of a stream starting with the displacement of common macro invertebrates and native alga. Attempts to…

Making Connections: Where Does Your Water Come From?

My previous post was in response to an argument against the proliferation of dams and diversions. Therefore I should also offer a response to this diametrically opposite perspective written by Richard Black, in the article “Drought summit: Why not pipe the water from north to south?”, calling for engineered solutions to droughts in southern England….

Man vs Nature – Aqueduct vs Stream: Monitoring, Understanding and Protecting

Aqueducts are to natural streams what wheat fields are to tall grass prairies. There is an undeniable elegance in form that comes from simplification of function to unity. Whereas any pristine stream serves many ecological, geomorphic, social, spiritual and economic functions, an aqueduct exists for the sole function of moving water from one place to…

The Future of Water Data Sharing – Discoverable, Searchable and Accessible

The Open Geospatial Consortium (OGC) is seeking public comment on part 1 of the new WaterML 2.0 data standard for time-series data encoding Aquatic Informatics is actively participating in the Hydrological Domain Working Group, which has a mandate from both the OGC and the World Meteorological Organization (WMO), to explore issues of hydrological data interoperability….

North American Stream Hydrographers

Measuring and monitoring streamflow is a place-based activity. Hydrographers are isolated from each other because of the size of the geographic domain each one can cover. Training opportunities and technology workshops are often organized along institutional lines. Hydrographers often have closer communication with distant colleagues in the same institution than they have with those operating…

62nd OGC Technical Committee Meeting – Boulder, Colorado

I attended 62nd OGC Technical Committee meeting in Boulder, Colorado with my colleague Stuart Hamilton in September. As most of you probably know, the Open Geospatial Consortium (OGC) is an international industry consortium of 438 companies, government agencies and universities participating in a consensus process to develop publicly available standards for geospatial data exchange protocol…
