Cheryl Nenn (Milwaukee Riverkeeper) explains to Faith Fitzpatrick (U.S. Geological Survey) how a Riverkeeper coordinates programs, communication, monitoring, maintenance, and volunteer organization related to urban stream restoration and protection.

This video shows how to ensure that the edge of one object in ModelMuse lines up exactly with the edge of another object.
 

In the USGS software ModelMuse, the user must assign spatially varying data to data sets, This video describes how to assign values to data sets in ModelMuse.
 

This video shows how to use ModelMuse to check that streams in a MODFLOW model and linked properly.
 

This video shows how to visualize spatial data in the USGS software ModelMuse by coloring cells or contouring the data.
 

This video shows how to plot of the residuals between the observed heads and the simulated heads in ModelMuse.
 

In the USGS software ModelMuse, "Objects" are used to specify spatially varying data. Sometimes it is useful to be able to edit several of these objects at the same time. This video shows how.
 

This video demonstrates how to export an image from ModelMuse into an editable image of the top, front, or side view of your model.
 

This video shows how to to import a MODFLOW-2005 model into ModelMuse
 

This video describes how to import Shapefiles into ModelMuse and use them to help set up a groundwater flow model.
 

This video illustrates differences among the various interpolation methods in ModelMuse.
 

This video shows how to use ModelMuse to specify layers in MODFLOW that vary in elevation.
 

This video shows how to measure distances in a model using ModelMuse
 

This video describes how to set up quasi-3D models in ModelMuse.
 

This video shows how to use the status bar in ModelMuse to obtain information about your model.

America has questions about climate change, and the USGS has real answers. In this episode of Climate Connections, USGS scientists answer questions gathered from Puerto Rico. Questions include:

- Why has the rainy season been so long in Puerto Rico?

- How is global warming impacting the island of Puerto Rico?

In this briefing USGS demonstrated a new and innovative online decision support system used to identify sources of nutrients to downstream waters, such as the Gulf of Mexico, Long Island Sound and others. The decision support system provides access to six newly-developed regional models that describe how rivers receive and transport nutrients to sensitive waters.

Following the Condit Dam removal, a significant amount of bedload sediment was transported downstream. As the material moved along the river bottom, dunes began to form then collapse. This dune formation is seen through the waveform action as the stream's normal laminar flow is replaced by whitecap wave forms before returning, once again, to laminar flow.
