The Impacts of Climate Change on Snowpack and Streamflow in the Western U.S. Webinar

Learn about the impacts of climate change on snowpack and streamflow in the western U.S. with WWA researchers Dr. Noah Molotch and Dr. Ben Livneh. Dr. Molotch presents his research mapping snow water equivalent in real time using satellite data, models, and ground stations. His presentation drew on collaborations with water resource stakeholders from across the western U.S. Dr. Livneh examined “snow drought” in the Colorado River Basin over the past century. He evaluated the importance of how snow drought is defined, its historical variability, as well as its role in modulating streamflow. He also summarized recently completed work that examines the impact of anomalously low snowpack on streamflow prediction across the West and discusses ongoing efforts that explore new tools in seasonal water supply prediction.

Snowpack Monitoring in the Rocky Mountain West Webinar, Part 1: Observations

Part 1 of a two-part webinar in which we shared Snowpack Monitoring in the Rocky Mountain West: A User Guide. Guest speakers Karl Wetlaufer (NRCS) and Jeff Deems (CIRES) discussed the details of snowpack observations, both in situ and remotely sensed: Where, how, and what data are collected, how are they organized, and how are they accessed?

WWA WebinarsThis third installment in the Colorado River Basin Climate and Hydrology: State of the Science report webinar series focused on Chapter 2, which covers moisture sources, storm tracks, seasonality of precipitation, the influence of topography and elevation, snowmelt, groundwater, mechanisms of variability, and recent trends. After summarizing the current understanding in these areas, Jeff Lukas and Liz Payton concluded with research challenges and opportunities, followed by Q&A.

Western Water Assessment's Jeff Lukas and Liz Payton, along with Steph McAfee (University of Nevada, Reno), took a closer look at the observations of weather, climate, and hydrology that are fundamental to Colorado River water supply, water demand, and system condition forecasts and projections.

This second installment in the Colorado River Basin Climate and Hydrology: State of the Science report webinar series focused on Chapters 4 & 5, which cover weather observation networks, procedures for developing gridded climate datasets, snowpack observation techniques, streamflow naturalization methods, and models for estimating evapotranspiration and soil moisture. Jeff Lukas, Liz Payton, and Steph McAfee discussed these topics and offered key challenges and opportunities for improving the data, followed by Q&A.

The Colorado River Basin Climate and Hydrology: State of the Science report was conceived and commissioned by a group of federal, state, and local water agencies working to advance scientific understanding in the Colorado River Basin. By serving as a common knowledge base and identifying challenges and opportunities, the report is intended to support ongoing efforts to improve near-term forecasts and longer-term projections of water supply and system conditions, and also inform broader discussions about planning for the basin's water future.

Western Water Assessment's Jeff Lukas and Liz Payton discussed an overview of the recently released report, Colorado River Basin Climate and Hydrology: State of the Science, followed by Q&A.

The report aims to create a shared understanding of the physical setting and the latest data, tools, and research underpinning the management of Colorado River water resources. With support and guidance from more than a dozen federal, state and local water agencies, the 17-author team led by WWA’s Jeff Lukas and Liz Payton integrated nearly 800 peer-reviewed studies, agency reports and other sources to assess the state of the science and the technical methods relevant to managing water resources in the Colorado River Basin.
