A Bayesian Approach to Address the Structural Uncertainty of Hydrological Models in Ungauged Catchments

Reliable predictions of available water resources are essential for water management and its related economic activities. These predictions typically come from rainfall runoff models, yet in the vast majority of the catchments across the world, no streamflow measurements are available. Producing reliable predictions in ungauged catchments remains a major research and applied challenge for the hydrological community. 

This talk will focus on two aspects of predictions in ungauged catchments: 1) the assumption that the pre-selected model and regionalization technique are a suitable and adequate representation of the behavior in the ungauged catchment, and 2) the identification of dominant hydrological mechanisms to be represented in hydrological models. 

First, hydrological indices (also named hydrological signatures) are selected using a principal components analysis. Second, the most significant principal components are regionalized using random forests regression techniques. Third, these regionalized principal components are assimilated into hydrological models using a Bayesian approach. Fourth, two metrics are proposed to assess model and regionalization suitability and adequacy. Suitability measures whether the model and regionalization are able to reproduce catchment behavior with a high probability, while adequacy measures the relative gain of knowledge of including a model or regionalization procedure. And fifth, a new procedure is introduced, which enables the identification of dominant hydrological mechanisms from regionalized information and an ensemble of models using a Bayesian approach.

The methodological developments have been applied to basins in northern Spain with diverse hydroclimatological regimes. The results indicate that the prediction quality is sensitive to the model error, to the quality of the regionalized information, and to the available information content.

Earth Day is tomorrow and we want to honor the important work that all NCAR|UCAR staff do on a daily basis by offering discounts at local bike (and electric bike) shops! Simply flash your building access badge at any of these participating businesses.

In Other Bike News-

Don’t forget to take advantage of your FREE annual B-cycle membership ($88 value). Your B-cycle membership gives you access to hundreds of bikes locally and thousands more across the country. It’s highly recommended that you take 5 minutes to register for your membership now so that you’ll be able to easily use the bikes when you’re out and about and need them in a pinch. Your future self will thank you when your hair is blowing in the wind. Click here for your promo code.

Earlier this month, the League of American Bicyclists recognized UCAR with a Gold level Bicycle Friendly Business award, joining a cutting-edge group of over 1,300 businesses, government agencies, and Fortune 500 companies across the United States that are transforming the American workplace. Out of the 1,300 institutions recognized, only 180 have received the Gold level award. “The business community’s investment in bicycling is playing a central role in making the country a safer, happier, and more sustainable place to live and work,” said Amelia Neptune, Director of the Bicycle Friendly America program. “We applaud this new round of businesses, including UCAR, for leading the charge in creating a bicycle-friendly America for everyone.”

Thank you for your continued commitment to environmental stewardship. Together, our collective efforts make a difference!

Statistical Framework for Modeling the Spatial Distribution of Orographic Precipitation
Paola Marson
University of Venice
Euro-Mediterranean Center on Climate Change (CMCC)

Most precipitation in the mid-latitudes is attributable to convective clouds and frontal systems.  Although their development is not induced by the underlying terrain, the orography can play a substantial role in altering their features.  The orographic moist flow dynamic interacts synergistically with thermodynamic and microphysical processes as well as with the large-scale flow.  A potential consequence is the modification of the spatial distribution of precipitation at the ground, which likely exhibits a highly segmented nature in both space and time.

Observed precipitation data are in general too coarse in space to be representative of the topographic variations of the “true” precipitation field.

Aiming at describing the spatial distribution of precipitation over complex terrain, we specify a statistical model which does not solely rely on observed data but also incorporates established analytical descriptions of the physical processes involved.

This is still a work in progress and we will show how we are developing the methodology as well as some preliminary results.

The National Science Foundation (NSF) and University of Wyoming, Laramie, invite NCAR/UCAR staff to participate in the upcoming NSF Day to be held on Wednesday, May 3, 2017 at the University of Wyoming Marian H. Rochelle Gateway Center, 222 South 22nd Street, Laramie, Wyoming.

NSF Days provide basic insight and instruction on how to compete for NSF funding for science, engineering and education research. This day-long workshop will provide background on the Foundation, its mission, priorities and budget.

During the day, NSF staff will give an overview on proposal writing, NSF's merit review process, and programs that fall within the NSF's seven scientific and engineering directorates, as well as funding opportunities that cross disciplinary boundaries. NSF representatives will be on hand to answer questions and to host discipline- and program-specific breakout sessions to personally engage in discussions with attendees.

There is no registration fee. This event is being provided as a courtesy to the regional scientific community. Register here (no later than April 28). 

More information is available on the NSF Day site.

On weekdays in winter, while most people are still sleeping, Rory Kelly is driving to a ski area in the dark, slipping into his ski mountaineering gear, and training for two hours before heading back to Boulder for his job as a software engineer in NCAR's Computational and Information Systems Laboratory (CISL). Many outstanding athletes work at NCAR. But Kelly is in somewhat rarified air, literally and figuratively. (Story by Jeff Smith, Science Writer and Public Information Officer. Read more here.)
