GISS Seminar, 2024-01-17: Augusto Getirana

GISS Lunch Seminar, 2024-01-17 Speaker: Augusto Getirana (NASA/GSFC/SSAI) Topic: Recent progress on flood modeling at NASA Goddard: From model development to capacity building Inland surface waters play an important role in global hydrology and water supply. It is also a main player in climate-induced disasters, as floods occurrences become more often worldwide. The development of advanced tools to represent, monitor and predict flood events at different spatial and temporal scales is crucial. At NASA Goddard Space Flight Center’s Hydrological Sciences Lab, we develop state-of-the-art hydrological modeling and data assimilation tools within NASA’s Land Information System, which is a modeling framework widely adopted by the international community. One of those tools is the Hydrological Modeling and Analysis Platform (HyMAP) global-scale flood model. In this seminar, HyMAP capabilities and three study cases using the model will be presented. In the first case, HyMAP is coupled to a land surface model and used to quantify the contribution of rivers and floodplains to global terrestrial water storage variability. The second case is a regional application where HyMAP is used to determine climate and human impacts on flood risk in Southern Louisiana. The third case is a local application with a capacity building component where an urban flood monitoring system is developed for the city of Rio de Janeiro, Brazil, and transferred for operations. The seminar will end with final considerations and prospects for future work.
