Climate controls on longshore sediment transport and coastal morphology adjacent to engineered inlets

Coastal jetties are commonly used throughout the world to stabilize channels and improve navigation through inlets. These engineered structures form artificial boundaries to littoral cells by reducing wave-driven longshore sediment transport across inlet entrances. Consequently, beaches adjacent to engineered inlets are subject to large gradients in longshore transport rates and are highly sensiti

Shifting sands: The influence of coral reefs on shoreline erosion from short-term storm protection to long-term disequilibrium

Climate change is exacerbating shoreline erosion and flooding, posing significant risks to coastal communities. Although traditional coastal defenses such as seawalls, dykes, and breakwaters offer protection from these hazards, their high environmental and economic costs are driving interest in cost-competitive nature-based solutions. Coral reef restoration is a nature-based solution that may be p

Postfire sediment mobilization and its downstream implications across California, 1984 – 2021

Fire facilitates erosion through changes in vegetation and soil, with major postfire erosion commonly occurring even with moderate rainfall. As climate warms, the western United States (U.S.) is experiencing an intensifying fire regime and increasing frequency of extreme rain. We evaluated whether these hydroclimatic changes are evident in patterns of postfire erosion by modeling hillslope erosion

Habitat Vulnerability to Climate Change: Identifying Climate Change Induced Mass Mortality Events Across Large Landscapes of the United States

USGS researchers will characterize extreme climatic events across U.S. following a review of case studies of mass mortality events associated with climate extremes including drought, precipitation, freeze, heat waves, and storm events.

Eyes on Earth Episode 120 – Mapping the California Coastline

Coastline erosion can change your favorite beach. But it can also affect highways and buildings. Landsat, along with high-resolution data, can be used to model the past and predict the future of changes caused by sea level rise and coastal erosion.
