The Colors of Water – Observing, Modeling and Understanding Precipitation Processes Across the World’s Mountains

Abstract: Water prediction at the temporal and spatial scales to make decisions that matter for resilience and prosperity of human and natural systems remains a quintessential civil and environmental engineering quest in the 21st century.  For those of us among the early generation of scientists and engineers who benefitted from NASA’s Mission to Planet Earth vision in the last quarter of the 20th century, the advent of ever-higher performance computing and Big Data, and met with the inevitability of interdisciplinary science, it’s been the most challenging and yet optimistic of times. Over the last two decades, my research group operated monitoring networks and conducted long-term water-cycle studies in mountainous regions high and small, including some of the most biodiverse hotspots in the world, that provide water resources to nearly two billion people and counting.  In this presentation, I will focus on selected research findings from our work in the Himalayas, the Andes, and the Appalachian Mountains that reveal the complex multi-scale multi-physics interactions at the interface of Ecology, Atmospheric and Hydrologic Sciences with implications for re-thinking engineering frameworks to address global water security and climate adaptation problems.

Hydroclimate Modeling and Water Resources Systems Engineering and Management: Expectations, Promises, Reality, and Prospects

Abstract: Addressing the needs of water resources management and hydrologic hazards requires information either from predictive models or traditional statistical methods. With the recent exponential growth in the number of publications related to the use of climate models and regional downscaling studies in water resources, it begs the question of how effective and valuable the results of these studies are to the “user community”. This presentation reviews the expectations, promises, reality and prospects of the applications of Hydroclimate modeling in addressing hydrologic and water resources problems. Recent advances in hydrometeorological high resolution observations of precipitation will also be discussed.

Hydrology in the Public Interest: Journey to Improve US Federal Guidelines for Flood Frequency Analysis

Abstract: US Federal agencies agreed on uniform floodflow frequency procedures in 1976 with publication of Bulletin 17, updated to Bulletin 17B in 1982, and finally Bulletin 17C in 2018. The interagency (HFAWG) Workgroup spent a decade testing and developing new robust methods adopted in Bulletin 17C. Important differences between Bulletin 17B and 17C are use of the Expected Moment Algorithm (EMA) that allows appropriate treatment of historical data, zero flows, censored crest-stage records, and Potentially Influential Low Floods (PILFs). Correct uncertainty analysis calculations were adopted. Recommended Bayesian regional GLS skew estimators indicate regional skews are much more accurate that previously described.  


Jery received a B.A. in Applied Mathematics from the University of California at Berkeley in 1972, and a Ph.D. in Environmental Systems Engineering from Harvard University in 1977. Since that time he has been a professor in Cornell’s School of Civil and Environmental Engineering. He spent his 1983-84 sabbatical at the U.S. Geological Survey’s national headquarters in Reston, Virginia, and his 1999 sabbatical at the US Army Corps of Engineers Institute for Water Resources at Ft. Belvoir, Virginia. He spent his 2005 sabbatical at the US Army Corps of Engineers Hydrologic Engineering Center (HEC) in Davis, California, and his 2010 sabbatical again with the U.S. Geological Survey in Reston, Virginia. His Fall 2017 sabbatical was with the Technische Universität Wien in Austria.

Dr. Stedinger’s research has focused on statistical issues in hydrology and optimal operation of water resource systems. Research projects have addressed the value of historical and paleoflood data in flood frequency analysis, regional hydrologic regression and network analyses, risk and uncertainty analysis of flood-risk reduction projects, calibration and uncertainty analysis for rainfall-runoff models, stochastic simulation of water resource systems, and efficient multiple-reservoir and hydropower system operation considering dynamic energy markets and stochastic inflows and forecasts. Other efforts address statistical issues associated with characterization of geothermal resources as part of the planning and risk assessment for such renewable energy projects.

Wood in Rivers: Insights from the Headwaters

Abstract: Drawing on three decades of field-based research in mountain streams of the Colorado Front Range, I summarize spatial and temporal patterns of large wood distribution in channels and floodplains and examine the implications with respect to fundamental river processes including hyporheic exchange, habitat, biomass, and organic carbon storage. Using the natural wood regime and wood process domains as a conceptual framework, I touch on implications for river management and restoration.


Ellen Wohl received a BS in geology from Arizona State University and a PhD in geosciences from the University of Arizona before joining the faculty at Colorado State University in 1989. Her research focuses on physical process and form in river corridors, including interactions with biotic and human communities. She has focused particularly on rivers in bedrock canyons and in mountainous regions, and she has conducted field research on every continent but Antarctica. She has written more than 200 scientific papers and book chapters, as well as 16 books, and is a Fellow of the American Geophysical Union and the Geological Society of America. Much of her current research examines how physical complexity associated with the presence of instream wood and beaver dams influences the form and function of river ecosystems.

Ellen’s research has followed an anabranching path through time. Her dissertation research focused on sedimentary records of ancient floods along bedrock canyons in northern Australia. Working in these canyons, she became intrigued by their channel morphology and the processes that created and maintained this morphology, so for several years she worked primarily on bedrock canyons. Many of these canyons occur in mountainous environments. Living in Colorado, the Front Range and Rocky Mountain National Park are the ‘backyard’ research sites, so my research focus shifted gradually toward mountain streams. The mountain streams of Colorado include a fair amount of instream wood. At some point she realized that most of the existing research on instream wood had been done in the very different environment of the Pacific Northwest, so that led her to focus on wood dynamics in Colorado and in headwater neotropical streams of Panama and Costa Rica. Wood dynamics in mountainous headwater streams are intimately connected to carbon cycling, stream metabolism, and river ecosystem productivity, and now several research projects focus on these aspects of mountain streams. In the course of mapping logjams in Rocky Mountain National Park, she kept coming across abandoned beaver dams, and began to wonder about the effects of these dams on carbon cycling and watershed-scale biogeochemistry. That’s a big component of the fun of research: you start on one path, but never know exactly where it will take you.
