Socioeconomic Impact Evaluation for Near Real-time Flood Detection in the Lower Mekong River Basin
Flood events pose a severe threat to communities in the Lower Mekong River Basin. The combination of population growth, urbanization, and economic development exacerbate the impacts of these events. Flood damage assessments, critical for understanding the effects of flooding on the local population and informing decision-makers about future risks, are frequently used to quantify the economic losses due to storms. Remote sensing systems provide a valuable tool for monitoring flood conditions and assessing their severity more rapidly than traditional post-event evaluations. The frequency and severity of extreme flood events are projected to increase, further highlighting the need for improved flood monitoring and impact analysis. In this study we integrate a socioeconomic damage assessment model with a near real-time flood remote sensing and decision support tool (NASA's Project Mekong). Direct damages to populations, infrastructure, and land cover are assessed using the 2011 Southeast Asian flood as a case study. Improved land use/land cover and flood depth assessments result in rapid loss estimates throughout the Mekong River Basin. Results suggest that rapid initial estimates of flood impacts can provide valuable information to governments, international agencies, and disaster responders in the wake of extreme flood events.

SWOT Applications in Alaska
Use of SWOT for model calibration and assimilation are encouraging, but further work is needed: account for uncertainty in meteorological forcing (calibration) and apply ensemble Kalman Smoother (data assimilation). Lessons learned can inform development of operational NOAA National Water Model Alaskan domain and other SWOT applications.

Hybrid Electric Turbofan Example Model
This powerpoint will be presented at a monthly Numerical Propulsion System Simulation (NPSS) Consortium monthly meeting. The presentation covers a simple example model that is being proposed to demonstrate how to model electrified propulsion systems in NPSS. The NPSS consortium expects to see its members modeling more electrified propulsion systems in the future and sees a need for a comprehensive example model for these systems, to demonstrate and standardize how these models are constructed.
