Ecosystem Dynamics, Project Chief: Coastal Habitats in Puget Sound - The goal of these projects is to develop scientific information and tools to support natural resource managers in the adaptive management of critical nearshore ecosystems in Puget Sound
Large-Scale Coastal Change, Project Chief: Southwest Washington Coastal Erosion Study - Research involves understanding complex relationships among sediment supply, littoral processes, and shoreline erosion or accretion in a high-energy coastal environment. Studies encompass multiple time and space scales of coastal evolution, and successfully differentiate natural and anthropogenic influences on coastal change.
Catastrophic Geologic Hazards, Co-Principal Investigator: Tsunami Hazards Study - Research effort to improve our understanding of tsunami hazards through identification and interpretation of sediments deposited from tsunamis

Large-scale dam removal on the Elwha River, Washington, USA: coastal geomorphic change
Two dams on the Elwha River, Washington State, USA trapped over 20 million m3 of mud, sand, and gravel since 1927, reducing downstream sediment fluxes and contributing to erosion of the river's coastal delta. The removal of the Elwha and Glines Canyon dams, initiated in September 2011, induced massive increases in river sediment...

Large-scale dam removal on the Elwha River, Washington, USA: source-to-sink sediment budget and synthesis
Understanding landscape responses to sediment supply changes constitutes a fundamental part of many problems in geomorphology, but opportunities to study such processes at field scales are rare. The phased removal of two large dams on the Elwha River, Washington, exposed 21 ± 3 million m3, or ~ 30 million ...

A survey of benthic sediment contaminants in reaches of the Columbia River Estuary based on channel sedimentation characteristics
While previous studies have documented contaminants in fish, sediments, water, and wildlife, few specifics are known about the spatial distribution of contaminants in the Columbia River Estuary (CRE). Our study goal was to characterize sediment contaminant detections and concentrations in reaches of the CRE that were concurrently being sampled to...

Little late Holocene strain accumulation and release on the Aleutian megathrust below the Shumagin Islands, Alaska
Can a predominantly creeping segment of a subduction zone generate a great (M > 8) earthquake? Despite Russian accounts of strong shaking and high tsunamis in 1788, geodetic observations above the Aleutian megathrust indicate creeping subduction across the Shumagin Islands segment, a well-known seismic gap. Seeking evidence for...

Time-dependent onshore tsunami response
While bulk measures of the onshore impact of a tsunami, including the maximum run-up elevation and inundation distance, are important for hazard planning, the temporal evolution of the onshore flow dynamics likely controls the extent of the onshore destruction and the erosion and deposition of sediment that occurs. However, the time-varying...

Validation of a coupled wave-flow model in a high-energy setting: the mouth of the Columbia River
A monthlong time series of wave, current, salinity, and suspended-sediment measurements was made at five sites on a transect across the Mouth of Columbia River (MCR). These data were used to calibrate and evaluate the performance of a coupled hydrodynamic and wave model for the MCR based on the Delft3D modeling system. The MCR is a dynamic...

Coastal processes of the Elwha River delta: Chapter 5 in Coastal habitats of the Elwha River, Washington--biological and physical patterns and processes prior to dam removal
To understand the effects of increased sediment supply from dam removal on marine habitats around the Elwha River delta, a basic understanding of the region’s coastal processes is necessary. This chapter provides a summary of the physical setting of the coast near the Elwha River delta, for the purpose of synthesizing the processes that move and...

Starting in September 2011, the removal of two large dams on the Elwha River will begin an unprecedented river restoration project because of the size of the dams, the volume of sediment released, the pristine watershed upstream of the dam sites, and the potential for renewing salmon populations. Ecosystem studies of the Elwha watershed indicate...
