New Model Shows Sea-level Rise Can Cause Increases in Groundwater Levels along California’s Coasts

A new model that combines sea-level rise scenarios and information about associated groundwater level responses shows that coastal water tables will rise as groundwater levels are pushed up by landward intrusions of seawater due to sea-level rise.

Recent Coastal and Marine Fieldwork - August-September 2020

USGS Coastal and Marine Hazards and Resources Program (CMHRP) scientists were able to safely venture out to collect beach elevations, geochemistry samples for wildfire contamination, water, soil, and meteorological data, offshore bathymetric and seismic data, ocean, lake, and bay sediment samples, and more, from Alaska, Washington, Oregon, and California, to Massachusetts, New York, and...

Spectral wave-driven bedload transport across a coral reef flat/lagoon complex

Coral reefs are an important source of sediment for reef-lined coasts by helping to maintain beaches while also providing protection in the form of wave energy dissipation. Understanding the mechanisms by which sediment is delivered to the coast as well as better constraining the total volumes generated are critical for projecting future coastal...

Littoral sediment from rivers: Patterns, rates and processes of river mouth morphodynamics

Rivers provide important sediment inputs to many littoral cells, thereby replenishing sand and gravel of beaches around the world. However, there is limited information about the patterns and processes of littoral-grade sediment transfer from rivers into coastal systems. Here I address these information gaps by examining topographic and...

Sediment export and impacts associated with river delta channelization compound estuary vulnerability to sea-level rise, Skagit River Delta, Washington, USA

Improved understanding of the budget and retention of sediment in river deltas is becoming increasingly important to mitigate and plan for impacts expected with sea level rise. In this study, analyses of historical bathymetric change, sediment core stratigraphy, and modeling are used to evaluate the sediment budget and environmental response of...
