ModelMuse screen capture to be used as a thumbnail for a video about creating meshes.

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.

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.

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.
