CI-WATER for Science Educators workshop a success

Science educators will soon have another opportunity to participate in CI-WATER for Science Educators, a professional development workshop featuring resources developed with support from the NSF-EPSCoR projects CI-WATER and iUTAH.

On August 4, 2015, nine Utah science educators participated in the pilot workshop, developed and facilitated by Utah’s Hogle Zoo Education Center. Participants commented on the value of connecting overarching concepts to education resources, which were developed with input from CI-WATER researchers at the 2013 CI-WATER Summer Teaching Institute. Hogle Zoo will facilitate more sessions of the successful workshop, using distance learning technology to make it more accessible to educators outside the metro area.

To learn about upcoming workshop or for more information, email Utah’s Hogle Zoo’s, Academic and Community Programs Coordinator, Suzanne Zgraggen.

Hogle Zoo and CI-WATER team up to offer science educator workshop

Science teachers for grades 8 through 12 are invited to register for CI-WATER for Science Educators, a two-hour professional development workshop for integrating water science and modeling resources into the science curriculum.

The workshop will be held at the Utah’s Hogle Zoo Education Center on Tuesday, August 4 from 1 to 3 p.m. The event is free to participants but seating is limited, so reservations are required.

Participants will learn about CI-WATER educator resources and engage in activities they can bring to their students.

“Water is no longer something we can simply take for granted. This workshop will help teachers prepare students for the future in which computer modeling will play an even greater role in water resource management,” says Chris Schmitz, Education Director at Hogle Zoo.

To register for the workshop or for more information, email Utah’s Hogle Zoo’s, Academic and Community Programs Coordinator, Suzanne Zgraggen.

CI-WATER research advances hydrologic science & engineering

With support from the National Science Foundation’s Experimental Program to Stimulate Competitive Research (NSF-EPSCoR), CI-WATER researchers have found a new approach that may revolutionize large-scale water modeling methods.

The discovery is of an alternative to a partial differential equation (PDE) that was published more than eighty years ago by soil physicist Lorenzo Adolph Richards.

“Previous solutions to the Richards equation are computationally expensive to run, unreliable and suffer from convergence problems,” says Dr. Fred Ogden, a CI-WATER Principle Investigator and lead author of the paper reporting the discovery. “We were looking for a faster, more reliable approach that conserves mass and is continuous.”

It seems that Fred and his collaborators have found it. An eight-month test to compare the predictive capabilities of the Richards’ PDE to the new “Finite-Water Content” solution in loam soil resulted in a minor variance, yet the latter solution appears to be robust, complete and more computationally economical—important when running data-massive simulations such as CI-WATER’s high-resolution, large-scale ADHydro model.

Details of the work were published in “A new general 1-D vadose zone flow solution method,” recently appearing in Water Resources Research, a publication of the American Geophysical Union (AGU). ADHydro, and other CI-WATER products, will be featured during the CUAHSI 3rd Annual Hydroinfomatics Conference next month.
