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

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.

What happened

New study provides rule of thumb to estimate land sustainability in river deltas Stephanie Baum Scientific Editor Robert Egan Associate Editor As densely populated coastal communities struggle to keep up with rising sea levels, new research reveals a way to…

Why it matters

This insight will help engineers and policymakers estimate how much new land can be created or maintained when human intervention is used to redirect river channels, making these efforts more effective for coastal restoration and flood protection.

Common ground

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…
