How to Solve 5 Common Discrete Water Sampling Challenges

It’s with great pleasure that I’m hosting this month’s webinar on February 28th about some of the most common discrete data management challenges. This topic comes up repeatedly in the field of environmental data management. Regardless of the size of your organization, I’m sure some of the challenges that we’re going to outline will resonate with you and your colleagues.

Linking the Flow of Data to the Flow of Water – Better Information Yields Better Outcomes

Inattention and imperfect information costs individuals, organizations and society in immeasurable ways. The relatively new field of information economics (infonomics) is revealing that great efficiencies can be gained by managing information as a strategic asset. All business decisions are made with the information available at the time. Yet, this availability is often a result of desperate scraping of whatever data happens to be readily accessible in real-time resulting in sub-optimal business outcomes. The new insight emerging from the study of infonomics is that decisions can be materially improved by anticipating needs and nurturing the information required to meet those needs.

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.

Shared Value - Hydrology Corner Blog

Creating Shared Value – Can Companies Solve the World’s Water Crisis?

It is increasingly the case that when I am talking to people about what AQUARIUS software ‘should’ do, I find that there are multiple motivations for what ‘should’ means. There are many different ways that value can be perceived and product development depends on this perception. The concept of “shared value” is where companies can solve society’s problems and make profit at the same time.

Water Nexus or Disjunction? Data will be the Difference

Much has been said about the water-energy-food nexus. The implication of many of these discussions is that we cannot disentangle policies for food and energy from each other because these sectors are inextricably linked by water. The nexus actually has many dimensions: you can add health, safety, economic activity, environmental sustainability, and social justice to…

The Economics of Hydrometric Data Quality

Data about water quantity and water quality are fundamental to some of the most important decisions made by engineers and in choices made by societies. Abundance and quality of water are critical factors in many aspects of our economy, our environment, and our social and physical well-being. It is the case than multiple water resources objectives must be simultaneously managed. The costs of sub-optimal water resources choices can be substantial. Uncertainty is antagonistic to optimization.

There Is Never Too Much Data!

There is more data to deal with than there used to be. However, dealing with it may require a different approach than simply working harder with the same tools. The new “Global Hydrological Monitoring Industry Trends” report confirms the rapid international adoption of continuous monitoring technologies. One of the questions asked of over 700 respondents…

Automation for Real-Time Hydrometric Data Production

Results from the 2012 Report – Global Hydrological Monitoring Industry Trends published by Aquatic Informatics Inc. The first Geostationary Operational Environmental Satellite (GOES) was launched in October 1975. The GOES launch initiated a sequence of events leading to a major re-design of hydrometric programs throughout North America. The relatively cheap and reliable data communication provided…
