This lecture by Prof. Reed Maxwell will discuss how computational advances are shaping our simulation capabilities, changing the questions that we are able to ask as scientist, and changing how we educate our students.
We are in the midst of a revolution in computing and data. In the past 50 years we have moved from electrical analog models to massively parallel computer systems. The fastest computers in the world when landmark papers such as Freeze and Harlan were written are much slower than the average smartphone of today. Hydrology is taking advantage of this revolution in many ways. Computational Hydrology seeks to leverage modern computing capacity to study water and energy fluxes and stores across the hydrologic cycle at spatial scales and complexity not previously possible. Integrated hydrologic simulations that couple boundary layer, vegetation, and land energy processes with surface and subsurface hydrology have great potential to advance our understanding of terrestrial hydrology spanning small catchments to the continental scale. Several movements within hydrology, such as the so-called hyperresolution approach, have organized and accelerated this goal. Hydrologic simulation from a historical perspective, starting with the early watershed models to more modern, integrated approaches that realize blueprints laid out fifty years ago will be presented. The lecture will discuss how computational advances are shaping our simulation capabilities, changing the questions that we are able to ask as scientist, and changing how we educate our students. High-resolution, continental-scale simulation is an exciting component of computational hydrology forecasting and scientific discovery. It will outline a path to move beyond our traditional siloed simulation platforms and to leverage these large datasets and massive community development investments to better connect our hydrologic models to the communities outside of hydrology.
About the Lecture Series
The Henry Darcy Distinguished Lecture Series in Groundwater Science fosters interest and excellence in groundwater science and technology. It was established in 1986 in honor of Henry Darcy of France for his 1856 investigations that established the physical basis upon which groundwater hydrogeology has been studied ever since. Each year, a panel of scientists and engineers invites an outstanding groundwater professional to share his or her work with their peers and students through an international lecture series.
2020 Darcy Lecture: Hydrology from the bottom up: how groundwater shapes the water cycle
This lecture by Prof. Reed Maxwell will explore the linkages between groundwater and the rest of the hydrologic cycle. It will discuss some fundamental relationships that describe groundwater's interconnections with land surface fluxes and how recent advances in our understanding these feedbacks can help us more holistically manage our watersheds.
2020 Darcy Lecture: Killer Beetles, Naked Trees, and Dirty Water: Understanding Hydrology and Water Quality Impacts from the Mountain Pine Beetle Infestation in the Rocky Mountain West
This lecture by Prof. Reed Maxwell will present research from a six-year project that brought together hydrologists, environmental engineers, social scientists and education and outreach specialists to study the broad water quality, quantity and social impacts of the MPB epidemic.
