Brief Bio

Dr. Dalia B. Kirschbaum is the Director of the Earth Sciences Division at NASA Goddard Space Flight Center, Greenbelt, MD. As Director she manages a staff of 200 civil servants and 1200 people serving as contractors, technicians, support staff and those on cooperative agreements, all dedicated to studying the Earth as an integrated system that includes the atmosphere, oceans, biosphere, cryosphere, and geosphere. Prior to this role, she was Chief of the Hydrological Sciences Laboratory, a group of scientists focused on conducting large-scale hydrological science research using data from NASA’s satellites, land surface models, and fieldwork. Dr. Kirschbaum’s research has focused on rainfall-triggered landslide modeling, monitoring and mapping using remotely sensed information to conduct landslide hazard and risk studies at multiple spatial and temporal scales. Previously, she also served as the Global Precipitation Measurement (GPM) Mission Deputy Project Scientist for Applications, and on the Atmosphere Observing System (AOS) Science and Applications Leadership Team. She has also supported the agency as a Disaster Response Coordinator, working with other NASA centers as well as domestic and international partners to bring satellite data and products to bear during natural hazard events to improve situational awareness and inform decision making. 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.

Research Interests

Landslide Hazard Modeling

Earth Science: Hydrology / Water Cycle

My 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. My current research focuses on advancing a regional landslide hazard and forecasting system with more quantitative and deterministic models to improve landslide hazard assessment. I am 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. This landslide interface represents the first regional/global interface to access landslide reports and contribute events to a global database. A prototype of our current system can be seen at

Application of remotely sensed precipitation data

Earth Science: Precipitation

This research involves evaluation and application of remotely sensed precipitation data from GPM and analyzing precipitation extremes as they relate to hydrometeorological hazards

Landslide Citizen Science

Earth Science: Human Dimensions

Dr. Kirschbaum and her team have developed a landslide citizen science system called "Landslide Reporter" that enables anyone to submit a report through the website: All reports are evaluated and then posted publicly on the Landslide Viewer portal.

Global Landslide Catalog

Earth Science: Applications

This work involves developing and maintaining a Global Landslide Catalog focused on rainfall-triggered landslides. Through this effort we are also working to developed a landslide citizen science portal, "Landslide Reporter" that will be an online portal to visualize, export, and edit this catalog and add additional events that is openly available to the public. This site will launch early in 2018.

Slope-stability modeling: sensitivity analysis and applications

Earth Science: Surface Properties

This work involves testing a physically-based slope-stability model over local and regional scales for improved assessment of landslide triggering conditions and sensitivity analysis of the inputs required to effectively model these processes.

Uncertainty evaluation of a regional real-time system for rain-induced landslides

May 15, 2015

A new prototype regional model and evaluation framework has been developed over Central America and the Caribbean region using satellite-based information including precipitation estimates, modeled soil moisture, topography, soils, as well as regionally available datasets such as road networks and distance to fault zones. The algorithm framework incorporates three variables: a static susceptibility map; a 24 rainfall triggering threshold; and an antecedent soil moisture variable threshold, which have been calibrated using historic landslide events. Dynamic thresholds are regionally heterogeneous and are based on the percentile distribution of the rainfall or antecedent moisture time series. A simple decision tree algorithm framework integrates all three variables and generates a landslide nowcast in real-time based on the previous 24 hours over this region.

This system has been evaluated using several available landslide inventories over the Central America and Caribbean region. Spatiotemporal uncertainty and evaluation metrics are presented here based on evaluation of landslides reported within the catalog as well as comparisons with other regional models. This work also presents a probabilistic representation of potential landslide activity over the region which can be used to further refine and improve the real-time landslide hazard assessment system as well as better identify and characterize the uncertainties inherent in this type of regional approach. The landslide algorithm provides a flexible framework to improve hazard estimation and reduce uncertainty at any spatial and temporal scale.

Uncertainty and Sensitivity analysis of a physically-based landslide model

May 17, 2015

Rainfall-induced landslides are hazardous to life and property. Rain data sources like satellite remote sensors combined with physically-based models of landslide initiation are a potentially economical solution for anticipating and early warning of possible landslide activity. In this work, we explore the output uncertainty of the physically-based USGS model, TRIGRS (Transient Rainfall Infiltration and Grid-Based Regional Slope-Stability) under both an a priori model parameter specification scenario and a model calibration scenario using a powerful stochastic optimization algorithm. We study a set of 50+ historic landslides over the Macon County in North Carolina as an example regional robust analysis. We then conduct a robust multivariate sensitivity analysis of the modeled output to various factors including rainfall forcing, initial and boundary conditions, and model parameters including topographic slope. Satellite rainfall uncertainty distributions are prescribed based on stochastic regressions to benchmark rain values at each location. Information about the most influential factors from sensitivity analysis will help to preferentially direct field work efforts towards associated observations. This will contribute to reducing output uncertainty in future modeling efforts. We also show how we can conveniently reduce model complexity considering negligibly influential factors to maintain example required levels of predictive accuracy and uncertainty.
