USGS hydrologic technician Jim Caldwell uses an aluminum tube and scale to measure snow depth, snow water content and snow density as part of the Maine Cooperative Snow Survey. This survey is conducted throughout Maine in the spring to aid in the evaluation of flood potential by the Maine River Flow Advisory Commission.

Screen capture of ModelMuse with the words "Objects are used to specify boundary conditions and observations."

Screen capture of ModelMuse with a mesh and the words "In SUTRA, some data are specified at nodes and some data are specified at elements."

ModelMuse screen capture with the text "This is the first of several videos that give an introduction to working with SUTRA in ModelMuse."

This video describes some of the most obvious changes to ModelMuse when working with SUTRA models.

This image shows a 3D SUTRA mesh that has layers that pinch out. The image is intended to be used as the thumbnail for a video.

ModelMuse screen capture with the words "This video will show how to run SUTRA and view the model results."

Scott Bendtson, a hydrologic technician with the Maine Office of the New England Water Science Center, is seen here making a discharge measurement through the ice on the St. John River at Ninemile Bridge, USGS station number 01010000.

Nick Stasulis, a hydrologic technician with the Maine Office of the New England Water Science Center, is seen here making a wading discharge measurement on the East Branch Wesserunsett Stream near Athens, USGS station number 01048220.

An ice jam on the East Branch Wesserunsett Stream in Athens, Maine in January 2014 left 3-5 ft ice walls on the riverbanks. On a January 21, 2014 site visit Nick Stasulis and Charlie Culbertson chisled away some of the ice wall so a discharge measurement could be made.

USGS hydrologic technician Bob Reaves collects streamflow measurements from the cableway at the USGS streamgage on the Snake River near Moran, WY. Jackson Lake Dam is shown in the background. Location: USGS streamgage station 13011000, Snake River near Moran, WY, Grand Teton National Park.
