Orthophoto survey drones help predict flash flooding

Orthophoto survey drones are offering new insights to scientists monitoring ice and water ranges in Alaska.

A analysis crew led by Gabriel Wolken of the College of Alaska Fairbank’s Local weather Adaptation Science Middle has been measuring rising and falling ice and water ranges in Suicide Basin glacial lake simply exterior Juneau.

By working to visualise and predict the glacial lake’s seasonal flux, the crew hopes to find out how the water interacts with the Mendenhall Glacier, which sits subsequent to the basin and holds it collectively.

“Mendenhall was as soon as linked to Suicide Glacier earlier than rising temperatures separated them, leading to Suicide Basin,” a spokesperson stated. “When basin waters rise to some extent, Mendenhall Glacier can’t maintain them anymore and your complete basin drains, instantly inflicting flash floods.”

Because of local weather change, flash flooding throughout Suicide Basin started in 2011, damaging native infrastructure within the valley a number of occasions.

“This flooding probably threatens a bridge that’s linked to the street system,” Wolken stated. “And that is the one street that may join residents on the north facet to hospitals and different important services, so if this bridge was impacted it might trigger some very critical points for lots of people.”

“The primary challenge is that it’s ice coated so we are able to’t actually see the water because it fills up the basin on a seasonal foundation,” he added.

The answer: The crew depends on orthophoto survey drones by Swiss UAV producer Wingtra to assemble digital elevation fashions and imagery. The info assist researchers assess adjustments to ice ranges atop Suicide Basin.

Wolken explains:

“Alaska is a giant place. There’s nearly nothing we tackle that we take into account small right here. So if it’s going to be a drone, we have now to have one thing that may really fly for a very long time, fly excessive sufficient to have the ability to deal with the advanced terrain that we’re always coping with and supply the decision that’s required for the analyses that we’re doing.”

A VTOL orthophoto survey drone mannequin, the WingtraOne, covers a big space effectively, offering high-quality knowledge when it comes to visualization and placement accuracy with out risking the security of a manned flight crew.

Final 12 months, Wingtra partnered with Statens Vegvesen, Norway’s Public Roads Administration, with vertical-take-off-and-landing drones to survey roads for knowledge evaluation and building projections.
