New study provides rule of thumb to estimate land sustainability in river deltas

Phys · · 502 words · By Lois Yoksoulian

Researchers from the University of Illinois Urbana-Champaign have identified a predictable pattern in river delta sediment deposition, similar to Hack's law. This finding may assist engineers and policymakers in estimating land build-up and optimizing coastal restoration and flood protection efforts.

“The new study, inspired by a 1950s-era finding called Hack's law—which states that the length of the longest tributary near the start of a river system is proportional to the size of its drainage basin—finds that coastal river deltas appear to follow a similar predictable pattern when it comes to sediment deposition.”
SINGLE SOURCE
The provided evidence consists of general information about the Mississippi and Ganga rivers and does not mention Hack's law or the specific study regarding coastal river deltas.
