Stream Velocity Rod – The Low-Cost, Low-Tech Tool That You Need in Your Field Truck

There are several highly sophisticated technologies available for measuring streamflow. However, no amount of electronic wizardry will guarantee that you come home with a good discharge measurement. There are many things that can wrong such as with the electrical power or electronic communication between the system components. In the event as an electronic failure you are screwed because these devices are so expensive that no one can afford to carry a spare.


Sensible Sense-Making From Sensor Observations for Sensitive Environmental Decisions

The theme of the CWRA 2016 conference in Montreal was “Water Management at all Scales: Reducing Vulnerability and Increasing Resilience”. Three days of presentations related to this theme got me thinking about what we need to be doing better in order to be better custodians of damaged, threatened and pristine water systems. We are the inheritors of a legacy of misguided decisions that have left many water sources (e.g. hillslopes, springs, wetlands), waterways, and sinks (e.g. oceans and deep aquifers) in an unhealthy state.

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…
