San Francisco Bay Basic Tide Model

This web page provides files that may be used to run a basic depth-averaged (2DH) Deltares Delft3D version 4.00.01 astronomic tide model for San Francisco Bay. It was developed with the primary aim of assessing water level fluctuations and flow conditions in the vicinity of the Golden Gate (Elias and Hansen 2013).

Using Video Imagery to Study Coastal Change: Barter Island, Alaska

For a short study period, two video cameras overlooked the coast from atop the coastal bluff of Barter Island in northern Alaska. The purpose was to observe and quantify coastal processes such as wave run-up, development of rip channels, bluff erosion, and movement of sandbars and ice floes.

Preliminary Analysis of the April 2007 Solomon Islands Tsunami, Southwest Pacific Ocean

The tsunami that was triggered by a magnitude 8.1 earthquake on April 1, 2007, in the Solomon Islands caused significant damage and loss of life. In the hopes that disasters such as this can be avoided in the future, we attempt to understand the mechanism and impact of this tsunami. The information presented here is focused on geologic aspects of the disaster.

Estuarine Processes, Hazards, and Ecosystems

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....

Coastal Landscape Response to Sea-Level Rise Assessment for the Northeastern United States

As part of the USGS Sea-Level Rise Hazards and Decision-Support project, this assessment seeks to predict the response to sea-level rise across the coastal landscape under a range of future scenarios by evaluating the likelihood of inundation as well as dynamic coastal change. The research is being conducted in conjunction with resource managers and decision makers from federal and state...

Coastal and Estuarine Dynamics Project

Coastal and Estuarine Dynamics Project exists to support ocean, coastal and estuarine research. The staff have a broad set of skills; from instrument design and development to all forms of work at sea to software development and data management. The team has successfully deployed and recovered more than 1000 data collection platforms for research in the last 30 years.

Digital Shoreline Analysis System (DSAS)

Computer Software for Calculating Shoreline Change (or positional change of a boundary over time)

The Digital Shoreline Analysis System (DSAS) v5.0 software is an add-in to Esri ArcGIS desktop 10.4-10.6 that enables a user to calculate rate-of-change statistics from multiple historical shoreline positions. It provides an automated method for establishing...

Cross-Shore and Inlets (CSI) Processes

Exchange of flows, sediment, and biological particles between the inner shelf and back-barrier estuaries are significant for determination of extreme water levels, maintenance and formation of inlets, barrier-island evolution, and pollutant and larval transport. These connections are controlled by cross-shore processes including wave-driven inner-shelf and near-shore processes, dune...

Coastal Model Applications and Field Measurements

Numerical models are used by scientists, engineers, coastal managers, and the public to understand and predict processes in the coastal ocean. This project supports the development and application of open-source coastal models and has several objectives: 1) improve the code of numerical sediment-transport models by implementing new or improved algorithms; 2) obtain measurements of coastal...
