Climate Change in Colorado: Impacts to Water Resources

Laurna Kaatz – Denver Water

Climate change, once considered a problem for the next generation, is one of the greatest challenges facing 21st century water resources. This presentation is an overview of climate change observations and projections for Colorado, and will set the stage for two technical presentations.

The development of cold content in a seasonal, mid-latitude snowpack and how it relates to melt timing and water availability

Keith Jennings  – PhD Student at University of Colorado Boulder

Cold content is the energy required to warm a sub-freezing snowpack to 0°C and is a key determinant of melt timing at daily and seasonal time scales. However, little is understood about seasonal snowpack cold content dynamics as calculating cold content requires depth-weighted snowpack temperature and snow water equivalent (SWE) measurements, which are scarce. In this study, we challenge current snow hydrology assumptions that cold content is acquired through cooling at the snow surface and that ground heat flux is a negligible component of the snowpack energy budget.

Analysis and comparison of the effects of climate change, mountain pine beetle infestations, and direct anthropogenic alterations on streams in the Rocky Mountains of Colorado, and a methodology for fusing multiple land cover products in space and time

Nicolas Rodríguez Jeangros – PhD Student at Colorado School of Mines

The Rocky Mountains (RM) have suffered various disturbances including unprecedented beetle infestations, water pollution, wildfires, and harvesting. Activities like urbanization and forest logging have highly affected the RM and climate change has provided optimal conditions for the mountain pine beetle (MPB) to shift its impacts from periodic and localized outbreaks to widespread epidemic infestations, affecting more than 5 million hectares of forest in North America.  The land cover (LC) is a critical variable driving many environmental processes, so its assessment, monitoring, and characterization are essential inputs to study those processes. In this study we developed a method for fusing multiple existing land cover (LC) products to evaluate the range anthropogenic impacts to the streams in the Colorado RM.

Speakers

Laurna Kaatz – Denver Water

Laurna Kaatz is the climate science, policy, and adaptation program director for Denver Water. Her primary responsibility is to lead climate investigations and implement findings to inform planning and policy. Laurna’s work incorporates many areas of water resource planning, including climate and drought planning, operational and water rights analysis, and long range integrated resource planning. Before her career at Denver Water, Laurna was a Professor of Physics at Sweet Briar College, and then went on to work as a climate science researcher with Aurora Water. Laurna has a Master’s degree in physics and a Bachelor’s in physics and mathematics.

Keith Jennings  – PhD Student at University of Colorado Boulder

Keith is currently a PhD student in the CU Boulder Geography Department and the Institute for Arctic and Alpine Research. His master’s degree is from Oregon State University in Water Resources Science where he was awarded the Provost’s Distinguished Fellowship and completed a thesis examining the importance of snowmelt-precipitation timing in generating extreme peak flows during rain-on-snow. Keith’s bachelor’s degree is in Environmental Science from the University of Vermont. In between his undergrad and master’s programs, he took a detour through Europe to race bikes for the US National Cycling Team.

Nicolas Rodríguez Jeangros – PhD Student at Colorado School of Mines

Nicolas is a Colombian Chemical and Environmental Engineer pursuing a doctorate degree in Environmental Engineering Science at Colorado School of Mines. He obtained his BS and MS from Los Andes University in Bogota, Colombia, where he researched the water quality of the Bogotá River and the urban drainage system of the city of Bogotá. He also worked as a researcher at Texas A&M. During his spare time, he enjoys spending time with his wife Amanda, doing triathlons, and learning about astrophysics.
