In SF Bay, even an exceptionally wet year can’t supply enough sediment to keep pace with rising seas, new study finds
2+ week, 5+ day ago (603+ words) Extreme rainfall can send huge amounts of sediment rushing off hillsides and into streams. But a new USGS study finds that even an exceptionally wet year may deliver only a small fraction of that sediment to San Francisco Bay—far…...

Morphodynamics of dune-based coastal flood mitigation under sea-level rise
1+ mon, 2+ week ago (545+ words) Natural and engineered sand dunes serve as barriers to protect against storms. Engineered sand dunes, called "Nature-based Solutions", are increasingly being used for coastal protection, yet their effectiveness remains understudied. New research finds that dunes' flood protection benefits depend not…...
