About the workshop

In collaboration with the Flood Forecasting and Warning Centre (FFWC)/Bangladesh Water Development Board (BWDB) in Bangladesh, we are organizing an orientation workshop on our flood inundation monitoring service. The workshop will introduce HydroSAR’s HYDRO30 surface water extent product along with its visualization capabilities to relevant stakeholders in Bangladesh. The workshop will also showcase a step-by-step method for accessing the product via the web-based application and solicit feedback from participants.


  • Provide information on the capabilities and limitations of the HYDRO30 surface water extent product and related products
  • Provide hands-on training on the web application
  • Solicit discussion and feedback on the customization of the web application and inclusion of additional features

Expected outcomes

By the end of the workshop, participants will have sufficient understanding of the capabilities of the surface water mapping products included in the service and will be able to use the associated web application.


HydroSAR is a NASA SERVIR Applied Sciences Team (AST) project that develops products, tools, and services to support monitoring hydrological hazards in the HKH region. A cloud-based SAR data analysis service, HydroSAR taps into research expertise from the University of Alaska Fairbanks, the NASA Marshall Space Flight Center, the NASA Goddard Space Flight Center, the NASA Jet Propulsion Laboratory, and ICIMOD. Derived from weather-independent Sentinel-1 SAR data, HydroSAR’s HYDRO30 surface water extent product provides near real-time information on flood water extent and is available within hours as a flood event progresses. This product can be extended throughout the lower plains of the HKH region. Floods are the most significant natural disaster affecting the HKH region because of their frequency, financial costs, and most importantly, the impact on populations and disruption of socio-economic activities. During flood events, remotely sensed geospatial data serves as a critical resource for information on surface inundation. Combined with information on demography and infrastructures, this information can aid line agencies in making informed decisions during their disaster risk reduction response and mitigation efforts.
