Hurricane Harvey dumped added than 5 anxiety (1.5 meters) of baptize on southeast Texas in backward August 2017, authoritative it the wettest recorded blow in U.S. history. But afterwards the storm passed, area did all that baptize go?

In a new, NASA-led study, scientists acclimated Global Positioning Arrangement (GPS) abstracts to acknowledgment that catechism and to clue not aloof area Harvey’s stormwater concluded up on land, but additionally how continued it took to dissipate.

“We bent that in the aboriginal eight canicule post-landfall, 30 percent of Harvey’s stormwater was captured or stored on acreage — best as continuing baptize that sits on the surface. About 60 percent was absent or drained into the ocean and Galveston Bay over the aboriginal few canicule afterwards the storm, and the actual 10 percent was absent via evapotranspiration, or a aggregate of dehydration and bulb transpiration,” said aboriginal columnist Chris Milliner of NASA’s Jet Propulsion Laboratory in Pasadena, California.

The 30 percent of baptize that was stored on acreage again gradually blown over a aeon of about bristles weeks, acceptable through evapotranspiration, groundwater runoff into adjacent rivers and the bushing of aquifers.

How It Works

Made up of satellites, receivers and arena stations amid about the world, GPS allows scientists to admeasurement changes in Earth’s apparent acclivity to an accurateness of beneath than an inch (a few millimeters). It works abundant like GPS on your adaptable buzz but with greater accuracy. The abstraction aggregation acclimated circadian acclivity abstracts from about 220 of these arena stations, from western Texas to Louisiana, to clue changes in the bulk of stormwater on acreage afterwards the hurricane.

“When you sit on a mattress, your weight depresses its surface. Earth’s band is additionally adaptable and behaves in a agnate way beneath the weight of water,” said Milliner. “GPS is barometer the bulk of subsidence (or depression), which tells you how abundant baptize accumulation charge be acute on the apparent and area that baptize is distributed.”

The aggregation bent that in the aboriginal several canicule afterwards Blow Harvey, the acreage about Houston bargain in acclivity by as abundant as 20 millimeters. The GPS abstracts additionally tracked a bright arrangement of acreage subsidence that migrated beyond the Gulf Coast over a seven-day period, constant with the position of Blow Harvey. Afterward this antecedent acreage subsidence, abstracts from GPS stations begin that Earth’s apparent gradually rose aback up, advertence baptize was clarification and abbreviating from acreage — aloof as a mattress behaves back you boring angle up and aish your weight from it.

To ascertain Earth’s mattress-like acknowledgment to changes in baptize mass, the aggregation aboriginal had to action the GPS abstracts to aish analytical errors alleged accepted approach absurdity (CME). CME acts about as “noise” that masks the hydrologic signal. Using an absolute component-analysis filter, the aggregation was able to statistically abstracted the raw GPS abstracts into CME and hydrologic signals. This accustomed them to abandon the arresting that was babble and abstract the attenuate hydrologic arresting they sought.

With the filtered GPS data, scientists were able to actuate the circadian consequence and area of the apparent abasement and from this account the circadian accumulation of baptize that acquired it.

The abstraction demonstrates — for the aboriginal time — that it is accessible to robustly quantify circadian changes in baptize accumulator afterward acute precipitation contest like above hurricanes. It allows us to see how abundant baptize is briefly stored on acreage afterwards a above hurricane, area it is stored, and how continued it takes for stored baptize to blow over time.

Scientists absent to accept how the hydrologic arrangement behaves in acknowledgment to ample storms account from this information, but so do baptize and flood managers. If they apperceive how abundant baptize was stored on acreage and how continued it took for the baptize to blow afterwards a above precipitation event, they accept a clearer compassionate of what to apprehend back the aing major, rain-intensive storm hits — and can adapt accordingly.

The study, blue-blooded “Tracking the Weight of Blow Harvey’s Stormwater Using GPS Data,” was afresh appear by the account Science Advances.
