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 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. And yet, some tribes have faced difficulties initiating and completing the critical first step of the climate adaptation planning process: an assessment of locally-specific climate risks that accounts for the unique priorities, values, and

This video provides basic information about the HydroLink Tool to get you up and running with the basic tool capabilities.
 

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. 

The marshes once stretched across nearly 5,800 square miles. This Landsat 5 image from 1986 shows lush vegetation and dark waters both

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

This is an animation showing the changing conditions of USGS streamgages from January 1, 2019 to June 1, 2019. The conditions shown range from the driest condition seen at a gage (red open circles) to the wettest (blue closed circles). There is also a purple ring added to indicate gages that are flooding. During the animation, three locations in TN broke record water

Title: New Mapping of the Rodgers Creek Fault: It's longer and more complex than we thought

• Remote sensing technology reveals surface traces of the fault covered by trees and buildings.
• Greater fault length and linkages to neighboring faults make larger earthquakes possible. 
• Fault complexity has implications for hazards from ground shaking

LP360 is a family of tools for visualizing, manipulating and editing point cloud data and are offered both as an extension for ArcGIS, and as a standalone desktop platform for Window. By the end of this lesson, you will be able to open LiDAR point cloud LAS data files in the LP360 Viewer, visualize the data in 2-D and 3-D, change the visualization using toolbar functions,

Global Mapper is a software package for visualizing, analyzing, manipulating, and exporting a wide variety of GIS data. By the end of this lesson, you will be able to open LiDAR point cloud LAS data files in Global Mapper, turn on all or specific LiDAR point Classes, visualize the data in 2-D and 3-D, and change the visualization using toolbar functions.
 

USGS Storm Tide Sensors are specialized scientific instruments used to measure the depth and duration of storm surge during coastal storms. The data these sensors collect before, during and after a storm will help public officials assess storm damage, and improve computer models used to forecast storm surge and coastal change. FEMA and other federal, state and local

USGS scientists are studying water-quality conditions and harmful algal blooms—known as HABs—in Owasco, Seneca and Skaneateles lakes in New York. The USGS monitoring effort will provide a better understanding of HAB growth and severity and allow for near instantaneous detection of changing water-quality conditions that might be indicative of HAB development. This will

Scientists with the USGS Yellowstone Volcano Observatory use satellite and aerial imagery to map hot springs, geothermal vents, and geysers at Yellowstone National Park. They recently found an entirely new thermal area miles from the nearest trailhead. Landsat 8's thermal infrared sensors captured the change in a nighttime image from April of 2017. Aerial images reveal a

This animation is the third video in a series explaining different aspects of the Phragmites Adaptive Management Framework (PAMF). This video focuses on the machine learning model that PAMF uses to systematically learn from participant's data and then provide site-specific management guidance in return. More information about PAMF can be found at our websites:

This timelapse sequence of webcam images over a 24-hour period shows a typical day at the summit of Mauna Loa. The webcam (MLcam) is located on the northeast rim of Moku‘āweoweo, Mauna Loa's summit caldera. This sequence begins in the dark, with the moon rising (white dot at left in images), then brightens as the sun rises. Clear skies in the morning shift to cloudy

In the Arctic, rivers are often thought to freeze completely during winter. Since fish need liquid water to survive, there are few places where they can live. Fish usually inhabit deep river channels and areas where springwater enters a stream. However, this video shows that winter habitat occurs in places we didn't expect, below the ice in the delta of a shallow river. 

Title: The Story of California's Changing Ecosystems: As observed from space

• How can we use images from space to help us understand changes to our coasts, rangelands, forests and wildlife habitats?
• How can they help to predict future changes?
• What more can we learn from advances in earth observing technologies?

Climate change is predicted to alter sport fish communities in Midwestern lakes, but managers currently have limited information on individual lakes that can be used to set local expectations or intervene with mitigation strategies. Northeast and North Central CASC supported researchers, with strong participation from the Midwest Glacial Lakes Partnership, have combined
