Wet Soils Increase Flooding During Atmospheric River Storms

Patterns and drivers of soil microbial carbon use efficiency across soil depths in forest ecosystems

Subsoils below 30 cm store more than half of global soil carbon. Microbial carbon use efficiency (CUE) serves as a key indicator of microbial control over soil carbon turnover, but the general patterns and drivers of microbial CUE across soil depths remain poorly understood. Here, we report a decreasing trend in microbial CUE with increasing soil depths through large-scale soil sampling across 60 sites spanning tropical to boreal forests. Using …

Wet soils increase flooding during atmospheric river storms

Atmospheric rivers are responsible for most flooding on the West Coast of the U.S., but they also bring much-needed moisture to the region. The size of these storms doesn't always translate to flood risk, however, as other factors on the ground play important roles. Now, a new study helps untangle the other drivers of flooding to help communities and water managers better prepare.

Wet Soils Increase Flooding During Atmospheric River Storms

A new study examined decades of atmospheric river storms across the West Coast to pinpoint the conditions that lead to catastrophic flooding. The research, published June 4 in the Journal of Hydrometeorology, analyzed more than 43,000 atmospheric river storms across 122 watersheds on the West Coast between 1980 and 2023.
