Happy holidays from all the contributors here at Hydrology Corner! It’s been another busy year at Hydrology Corner with many insightful and important discussions on a range of themes such as water resource management, estimating alpha, and women in the water industry.
Laboratory analysis of a water quality sample links a lot of data to a singular point in time and space. However, the objectives for monitoring may span scales from point (e.g. at an outfall) to watershed (e.g. to characterize waters; identify trends; assess threats; inform pollution control; guide environmental emergency response; and support the development, implementation, and assessment of policies and regulations).
Evidence-based decision-making is a useful framework for the development of policies and practices to ensure water security, ecosystem resilience, and productive societies. The term “evidence-based” is gradually yielding to the term “data-driven” as focus shifts from specified data (i.e. fit-for purpose) to data discovery (i.e. big data) as the source of evidence.
I was recently asked to explain why I recommend starting from a value of 1 (i.e., unity) as a first guess for the velocity coefficient for unconstrained alluvial channels. This probably does deserve an explanation (or 4) because I’ve never heard anyone else recommend the unity conjecture, in spite of the inherent elegance of such simplicity.
A new report, “Future Water Priorities for the Nation: Directions for the U.S. Geological Survey Water Mission Area,” speaks to water science and resources challenges for the next 25 years. While written specifically for the Water Mission Area (WMA) for the United States Geological Survey (USGS), the driving forces for change are applicable to any region of the world.
The African continent is characterized by diverse geographic features, climates, and cultures but a common denominator is that African nations are working hard to improve social stability, economic security, public health, and environmental sustainability. Solutions emerging from various political adventures seem to be evolving toward a mix of governance approaches sourced from the west (based on an ideal of democratic capitalism) and those sourced from the east (based on an ideal of progressive socialism).
Water has always been important. The perception of its importance is closely linked to episodes of too much, too little, or the wrong quality. Climate change, urban growth, and agricultural intensification are just three examples of pressures that are contributing to an unprecedented global awareness of the importance of water.
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.
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.
