Rainfall-triggered landslides occur in nearly every country around the world, produce billions of dollars of damages and cause thousands of fatalities, and that is just in one year. Understanding and modeling the dynamics of rainfall-triggered landslides is a challenging task due to precipitation variability and the higher complexity of land hydromechanics compared to typical land surface hydrologic representations. Satellite data provides a unique perspective to estimate landslide triggering, but the accuracy of the modeling is highly reliant on the scale and methodology at which the evaluation is considered. This presentation outlines several different on-going efforts to model landslide behavior at different spatial and temporal scales using deterministic, statistical and empirical methodologies. From a single hillslope in Washington to the entire region of Central America to a global landslide cataloging effort, we will explore the trials, tribulations, and triumphs of modeling landslide hazards over various climatologic, topographic and political settings.
Dr. Dalia Kirschbaum is a Research Physical Scientist in the Hydrological Sciences Lab at NASA Goddard Space Flight Center, Greenbelt, MD. Her research interests center on rainfall-triggered landslide modeling, focusing on applying remotely sensed surface and precipitation information to landslide hazard models at multiple spatial and temporal scales. Her current research focuses on advancing a regional landslide hazard and forecasting system with more quantitative and deterministic models to improve landslide hazard assessment. She is also developing a web-based interface for visualization of landslide hazard and remote sensing products for improved situational awareness of landslide hazards and reported events. Dr. Kirschbaum is also the Applications Scientist and Education and Outreach Coordinator for the Global Precipitation Measurement (GPM) Mission. As GPM Applications Scientist, she provides scientific support for applications research and activities for the Precipitation Measurement Missions (PMM). She coordinates GPM’s education and public outreach projects and leads a team of scientists, educators, and technical specialists to communicate the science and societal applications of the GPM mission to the general public. Dr. Kirschbaum received her M.S. and Ph.D. in Earth and Environmental Sciences from Columbia University with a focus in Natural Hazards and Remote Sensing. She received her A.B. in Geosciences from Princeton University.
