New findings reportedly extend Hack's law linking river length to drainage area
↗
A 2026 discovery has extended Hack's law, the 1957 scaling relationship stating that stream length is proportional to drainage area raised to the 0.6 power, which has held worldwide as satellite data improved.
The provided material cuts off before describing what the 2026 extension actually changed, so the concrete advance cannot be assessed. Hack's law itself is well-established and has been corroborated globally, but the specific new findings are not available in the extract given.

Hack's law, discovered in 1957 by a U.S. Geological Survey scientist, states that stream length is proportional to drainage area raised to the power of 0.6.
The law has held worldwide as more and better satellite data has accrued, regardless of geological or structural characteristics of the area.
A 2026 discovery reportedly extended the law further, but the provided extract cuts off before describing the extension.
