This video reviews the requirements and instructions for installing the Digital Shoreline Analysis System (DSAS) v5.0. For more information please visit the DSAS project page: https://woodshole.er.usgs.gov/project-pages/DSAS/ 

This video describes the high-water marks needed along with cross-section locations for critical depth indirect measurements. Critical depth computations are those performed when flow goes through a critical flow regime at a drop, such as at a waterfall. 
 

This video describes the survey requirements for culvert indirect measurements, specifically how to measure various aspects of the culvert itself. This video provides a general overview of how to survey culvert attributes, such as the invert and length.
 

See St. Joseph Bay in the Florida Panhandle through the eyes of two young adult female loggerheads as they swim, surface to breathe, dive, forage on underwater grasses and spend time with other sea turtles. Three species of threatened or endangered sea turtles congregate in St. Joseph Bay.

Mike Poland, Scientist-in-Charge of the Yellowstone Volcano Observatory, describes activity at Yellowstone during the month of June, 2019.

 

This video discusses how to measure various aspects of non-standard culverts, such as mitered culverts. Using the slope-area method inside a culvert is also discussed. 
 

This video details how to survey indirect measurements with GNSS. Both RTN and RTK setups are discussed, along with tips and tricks and troubleshooting.
 

Title: USGS Fire Science: Understanding why wildlands burn and what can be done about it

National Hydrography Advisory Call:

This video describes the survey requirements for culvert indirect measurements, including high-water mark and cross-section locations. 
 

This video demonstrates how to measure various aspects of pipe and pipe-arch culverts for culvert indirect measurements. The video includes tips and tricks for measuring the geometry, corrugations, and entrance types including rounded or beveled entrances.
 

This video demonstrates how to select an appropriate location for an indirect measurement. Theory and initial reconnaissance are discussed. 

This video shows how to survey a slope-conveyance indirect measurement using a conventional optical or digital level. 
 

This video details how to measure various aspects of a box culvert for a culvert indirect measurement. The video includes tips and tricks for measuring the geometry, wingwall angles, and entrance types including rounded or beveled entrances.
 

This video gives an overview of what it mean to be an International Cooperator, including information on what is an International Cooperator, who represents the International Cooperator community, what are the benefits of being an International Cooperator, and what does it mean to be an International Cooperator.

This video gives an overview of what it mean to be an International Cooperator, including information on what is an International Cooperator, who represents the International Cooperator community, what are the benefits of being an International Cooperator, and what does it mean to be an International Cooperator.

This video provides an introduction to the slope-conveyance method of indirect measurement. Theory and background are described as well as high-water mark and cross-section placement. 
 

Tribes have been actively engaged in efforts to anticipate and respond to climate impacts on their natural and cultural resources.

This animation takes the viewer down the Glen Canyon from Bullfrog Bay to the Rincon, in the Glen Canyon National Recreation Area. New high resolution multibeam bathymetry collected by the USGS in 2018 shows the submerged portions of Glen Canyon. 
 

The Marsh Arabs of southeastern Iraq have spent millennia traversing the waterways at the confluence of the Tigris and Euphrates rivers. The recent history of those wetlands, however, has been one of forced loss and uneven recovery.
