Floods

The USGS Pacific Coastal and Marine Science Center (PCMSC) in Santa Cruz, California, has been growing our post-fire research contributions since 2017, through studies of post-fire sediment movement that address the Natural Hazards Mission Area objectives for understanding wildfire hazards.

The U.S. Geological Survey (USGS) uses observations of flooding in communities to monitor hazard conditions and support research by the USGS and its partners into a variety of hazard processes in Alaska. Local observations of flooding at a flood staffs are used to document flood elevations, improve flood models, and support floodplain management decisions.

At the USGS Astrogeology Science Center we conduct research on Planetary Defense. Planetary Defense involves predicting potential impactors (asteroids, comets), and studying how to deflect or divert them, as well as the potential effects of an impact. Effects include short-term effects such as blast damage, but also long-term effects such as climate and social impacts.

Sea level is rising faster than projected in the western Pacific, so understanding how wave-driven coastal flooding will affect inhabited, low-lying islands—most notably, the familiar ring-shaped atolls—as well as the low-elevation areas of high islands in the Pacific Ocean, is critical for decision-makers in protecting infrastructure or relocating resources and people.

The Coastal Storm Modeling System (CoSMoS) makes detailed predictions of storm-induced coastal flooding, erosion, and cliff failures over large geographic scales. CoSMoS was developed for hindcast studies, operational applications and future climate scenarios to provide emergency responders and coastal planners with critical storm-hazards information that can be used to increase public safety...

Coastal flooding and erosion from extreme weather events affect thousands of vulnerable coastal communities; the impacts of coastal flooding are predicted to worsen during this century because of population growth and climate change. Hurricanes Irma and Maria in 2017 were particularly devasting to humans and natural communities. The coral reefs off the State of Florida and the Commonwealth of...

The Elwha River Restoration Project has reconnected the water, salmon, and sediment of a pristine river and coast of the Olympic Peninsula of Washington.

CoSMoS v3.1 for central California shows projections for future climate scenarios (sea-level rise and storms)

Estuarine processes, hazards, and ecosystems describes several interdisciplinary projects that aim to quantify and understand estuarine processes through observations and numerical modeling. Both the spatial and temporal scales of these mechanisms are important, and therefore require modern instrumentation and state-of-the-art hydrodynamic models. These projects are led from the U.S. Geological...

A modeled scenario of U.S. West Coast winter storm events induced by the formation of Atmospheric Rivers (AR) and capable of causing massive and devastating flooding.
