CI-WATER research advances hydrologic science & engineering
With support from the National Science Foundation’s Established 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.More Information...

ADHydro workshop offered at CUAHSI Hydroinformatics Conference
Participants in the 3rd Annual CUAHSI Hydroinformatics Conference will have the opportunity to engage in a hands-on exploration of a powerful new model for water resource researchers: ADHydro.
Created by a CI-WATER team led by University of Wyoming’s Dr. Fred Ogden, ADHydro has been designed from the ground up to operate in a massively parallel computing environment for efficient, large-scale simulations. The innovative model uses an unstructured mesh that allows users to direct high resolution visualization only where needed.
CI-WATER is holding a one-day workshop at the 3rd Annual CUAHSI Conference on Hydroinformatics on Friday, July 17, 2015. Due to time restrictions, participants in this free workshop must have Linux and other experience as detailed here.
