Amphibian monitoring in the National Capital Region
The National Capital Region Network has identified amphibians as a priority taxonomic group for its Inventory and Monitoring program. Amphibian monitoring was initiated in 2005, and is currently concentrated in Chesapeake and Ohio Canal National Historic Park (CHOH) and Rock Creek Park (ROCR), with stream sampling also occurring in Prince William Forest Park (PRWI).
Scenario-Based Assessments for Coastal Change Hazard Forecasts
A decade of USGS research on storm-driven coastal change hazards has provided the data and modeling capabilities needed to identify areas of our coastline that are likely to experience extreme and potentially hazardous erosion during an extreme storm.
National Assessment of Storm-Induced Coastal Change Hazards
This project focuses on understanding the magnitude and variability of extreme storm impacts on sandy beaches. The overall objective is to improve real-time and scenario-based predictions of coastal change to support management of coastal infrastructure, resources, and safety.
National Assessment of Coastal Vulnerability to Sea Level Rise
The original national coastal vulnerability index (CVI) assessment was motivated by expected accelerated sea-level rise (SLR) and the uncertainty in the response of the coastline to SLR. This research was conducted between 1999 and 2001, and is currently being updated using new data sources and methodology. This original study was part of the ...
Long-Term Coastal Change

Long-Term Response Monitoring of Suspended-Sediment Transport Characteristics on the Patapsco River near Ellicott City, Maryland, in Response to the Removal of Simkins Dam, 2010-present
For over 100 years, the Patapsco River has been impacted by the presence of several dams that were designed and built at the beginning of the 20th century. The objective of the project is to monitor suspended-sediment transport resulting from the removal of Simkins Dam on the lower Patapsco River in November 2010. The role of USGS in the project includes operation and maintenance of 3 stream...

Information about scientific data collected through field activities conducted by scientists in the USGS Coastal and Marine Hazards and Resources program

The NWIS mapper provides access to over 1.5 million sites contained in the USGS National Water Information System (NWIS), including sites where current and historical surface-water, groundwater, springs, and atmospheric data has been collected. Users can search by site type, data type, site number, or place.
Interactively explore assessment summary information for continuous (unconventional) assessments conducted at the USGS from 2000-2018. The assessment results data used to generate this visualization can be downloaded here in Excel Format. These data represent all assessment results for Continuous Assessments only from 2000-2018.

Obique photos offer a unique perspective of the coast. Features such as beach erosion or accretion, dune erosion and overwash can all be clearly characterized in this imagery. It also documents coastal infrastructure, as well as the damage that infrastructure may incur as the result of an impacting hurricane.

The National Water Information System (NWIS) web application provides access to real-time and historical surface-water, groundwater, water-quality, and water-use data collected at approximately 1.5 million sites across all 50 states.

The USGS Flood Event Viewer (FEV) is the public data discovery component of the Short-Term Network (STN) database. Data viewable and downloadable from this page are from the STN database. This application integrates with the USGS National Water Information System (NWIS) database for display of time-series water data.

USGS data portray selected structures data, including the location and characteristics of manmade facilities. Characteristics consist of a structure's physical form (footprint), function, name, location, and detailed information about the structure. The types of structures collected are largely determined by the needs of the disaster planning and response and homeland security organizations.

Boundaries data or governmental units represent major civil areas including states, counties, Federal, and Native American lands, and incorporated places such as cities and towns.

The National Hydrography Dataset (NHD) and Watershed Boundary Dataset (WBD) are used to portray surface water on The National Map.

The USIEI is a comprehensive, nationwide listing of known high-accuracy topographic and bathymetric data for the United States and its territories. The project is a collaborative effort of the USGS and NOAA with contributions from other federal agencies. The inventory supports the 3D Elevation Program and the Integrated Ocean and Coastal Mapping effort. This resource is updated in Spring and Fall.

The 3DEP products and services available through The National Map consist of lidar point clouds (LPC), standard digital elevation models (DEMs) at various horizontal resolutions, elevation source and associated datasets, an elevation point query service and bulk point query service. All 3DEP products are available, free of charge and without use restrictions.

Orthoimagery data typically are high resolution aerial images that combine the visual attributes of an aerial photograph with the spatial accuracy and reliability of a planimetric map. The National Map offers public domain, 1-meter orthoimagery for the conterminous United States with many urban areas and other locations at 2-foot or finer resolution.
This map shows the provinces assessed by the USGS for undiscovered oil and gas resources.

Amplification of earthquake ground motions in Washington, DC, and implications for hazard assessments in central and eastern North America
The extent of damage in Washington, DC, from the 2011 Mw 5.8 Mineral, VA, earthquake was surprising for an epicenter 130 km away; U.S. Geological Survey “Did-You-Feel-It” reports suggest that Atlantic Coastal Plain and other unconsolidated sediments amplified ground motions in the city. We measure this amplification relative to...
