In July heavy rains triggered landslides and floods in Nepal that ultimately killed more 130 people. Equally soon as the pelting started falling, BYU professor Jim Nelson knew things could get bad.
That's because the h2o-modeling software created by Nelson and colleagues from NASA under the Grouping on Earth Observations Global H2o Sustainability (GEOGloWS ) Partnership can predict the ascent and fall of every river on the confront of the planet. And in the case of Nepal, the streamflow forecasts were warning of astringent flooding throughout the country.
Fortunately, the predictive models, accessible through the BYU software, fabricated it into the hands of emergency agencies in Nepal, saving many lives in what could have been a catastrophic loss of life.
Nepali officials existence able to access this vital information through Nelson's large-scale visualization hydrologic data services was not a lucky break — it was by blueprint. The models are a key tool in a chop-chop expanding initiative from NASA and the U.S. Agency for International Development called NASA SERVIR , whose vision is to bring "Space to Hamlet," past leveraging satellite-based Earth monitoring, imaging and mapping systems that help people worldwide appraise ecological threats and apace respond to natural disasters.
"Our tools assist directly assess both flood risk and drought risk," said Nelson, professor of ceremonious and environmental engineering at BYU and principal investigator with the NASA SERVIR Practical Sciences Team. "Most communities effectually the globe alive around rivers, so having advanced notice becomes really important. We are providing the data then local governments and agencies can make intelligent, informed decisions."
SERVIR is up and running in more than 30 countries and includes more than 40 custom tools for local agencies to use in determination making. Spider web-based satellite imagery, conclusion-support tools and interactive visualization capabilities previously inaccessible across many regions at present enable stakeholders to combat floods, wildfires, superstorms and other calamities.
The real genius of SERVIR — which ways "to serve" in Castilian — is in making the data available to increasingly remote locations where access to information and cyberinfrastructure is limited. Cheers to additional NSF funding, Nelson and his colleagues were able to transition to open-source software, allowing for a shift from desktop computing to cloud calculating. Now regional h2o agencies across the world need not run programs that require significant estimator and information resources they don't have; they just login and admission location-specific and relevant data from cloud servers that are updated daily
Nelson describes it as a portal arrangement that operates similar to apps on a smart phone — just as you open up one app to bank check the conditions and some other to check messages, the portal has several different tools that can be accessed: 1 provides rainfall info, another groundwater levels and yet another forecasts streamflow. Local agencies can customize the applications and get the data they want to make the nearly informed decisions.
"Through his work with SERVIR, Jim has developed new and innovative techniques to downscale and visualize the latest streamflow forecasts, thus making them actionable at the local level and resulting in uptake from several governments in the Himalayan region," said Dan Irwin, global program managing director for SERVIR. "Jim is a world-class scientist, merely what'south particularly heady is his applied focus and passion to brand his science actionable to people in the developing globe. He strives to securely understand the issues in the region in which he is working, and then apply the best and most appropriate science."
And Nelson isn't the only BYU kinesthesia member involved with SERVIR. Fellow civil and environmental technology professor Norm Jones was role of Nelson'southward starting time Applied Sciences Team for NASA and has at present been selected for a SERVIR projection in West Africa addressing groundwater challenges. Professors Dan Ames and Gus Williams, besides in the same section, and Amanda Hughes of the School of Technology are co-Investigators on these two projects.
Ames is too working on a critical piece of earth scientific discipline cyberinfrastructure for the GEOGLOWS software ecosystem to overcome the limitations of storage, processing speed, transmission bandwidth and platform dependency associated with desktop computing.
GEOGloWS co-chair Angelica Gutierrez talked well-nigh the complication of the water crisis around the world and highlighted the collaborative approach nether GEOGloWS to provide a user-driven solution to the lack of streamflow forecasting information.
"The BYU activities within this try, have been the mucilage to keeping such a big consortium of influential organizations — USAID-NASA-SERVIR, the European Centre for Medium-Range Weather Forecasts (ECMWF), the National Oceanic Atmospheric Assistants (NOAA), The World Bank, and many others — tied together in an effective partnership to provide water information where trivial or none exists," said Gutierrez, who is also a atomic number 82 scientist at the NOAA. "The complex task of delivering information through services, requires a vision that only strong organizations and leaders in their fields, are pursuing under this partnership to brand great things happen."
