“"We determined that in the first eight days post-landfall, 30 percent of Harvey's stormwater was captured or stored on land -- most as standing water that sits on the surface. Around 60 percent was lost or drained into the ocean and Galveston Bay over the first few days after the storm, and the remaining 10 percent was lost via evapotranspiration, or a combination of evaporation and plant transpiration," said first author Chris Milliner of NASA's Jet Propulsion Laboratory in Pasadena, California.”
