Sedimentary evidence of prehistoric distant-source tsunamis in the Hawaiian Islands Sedimentary evidence of prehistoric distant-source tsunamis in the Hawaiian Islands
Over the past 200 years of written records, the Hawaiian Islands have experienced tens of tsunamis generated by earthquakes in the subduction zones of the Pacific "Ring of Fire" (e.g., Alaska-Aleutian, Kuril-Kamchatka, Chile, and Japan). Mapping and dating anomalous beds of sand and silt deposited by tsunamis in low-lying areas along Pacific coasts, even those distant from subduction...

A revised continuous surface elevation model for modeling A revised continuous surface elevation model for modeling
A digital elevation model (DEM) is an essential component of any hydrodynamic model. The Delta Modeling Section (Section) has maintained a database of bathymetry soundings and levee surveys for decades and published a 10-meter (10m) DEM for the San Francisco Bay and Sacramento-San Joaquin Delta (Delta) (California Department of Water Resources 2012). In collaboration with the U.S...

Slough evolution and legacy mercury remobilization induced by wetland restoration in South San Francisco Bay Slough evolution and legacy mercury remobilization induced by wetland restoration in South San Francisco Bay
Coastal wetlands have a long history of degradation and destruction due to human development. Now recognized as one of the most productive ecosystems in the world, substantial efforts are being made to restore this critical habitat. While wetland restoration efforts are generally viewed as beneficial in terms of providing wildlife habitat and flood control, they are often accompanied by...

Organic geochemical investigation of far‐field tsunami deposits of the Kahana Valley, O'ahu, Hawai'i Organic geochemical investigation of far‐field tsunami deposits of the Kahana Valley, O'ahu, Hawai'i
Far‐field tsunami deposits observed in the Kahana Valley, O'ahu, Hawai'i (USA), were investigated for their organic‐geochemical content. During short high‐energy events, (tsunamis and storms) organic and chemical components are transported with sediment from marine to terrestrial areas. This study investigates the use of anthropogenic based organic geochemical compounds (such as...

Bed shear stress estimation under wave conditions using near-bottom measurements: Comparison of methods Bed shear stress estimation under wave conditions using near-bottom measurements: Comparison of methods
Understanding the influence of waves on bed shear stress is critical for predicting morphodynamical behaviours in coastal areas. Near-bed flow was measured on the middle and lower intertidal mudflats along the Jiangsu coast, China, using a three-dimensional acoustic velocimeter that collected a 3.5-cm vertical profile at 1mm resolution and sample rate of 25 Hz. On the lower and middle...

Modeling morphodynamic development in the Alviso Slough system, South San Francisco Bay, California Modeling morphodynamic development in the Alviso Slough system, South San Francisco Bay, California
Alviso Slough area, South San Francisco Bay, California, is the site of an ongoing effort to restore former salt production ponds to intertidal habitat. As restoration proceeds and the levees surrounding the former salt production ponds are breached, the increase in tidal prism and associated sediment scour in the sloughs will remobilize legacy mercury deposits. A numerical model that is...
