This series of self-guided tutorials presents information on water, ecosystems, and energy resources. Animations of ecosystem processes enhance the text, and a summary of the important concepts covered in each topic as well as a glossary are provided. Topics include groundwater contamination and supply, the Great Lakes, coastal dunes, urban ecosystems, home energy use, energy resources, eecosystems ... Full description.

This site provides a variety of visual resources about waterfalls. Flash animations show how waterfalls, plunge pools and gorges are created by the erosion of underlying rock by flowing water. A QuickTime movie gives examples of large-scale waterfalls from around the world, and an interactive diagram illustrates how falling water is used to generate hydroelectric power. These resources are suitable ... Full description.

This site features Flash animations and QuickTime movies that illustrate some of the processes associated with river erosion, transport and deposition. Topics include sediment transport processes, such as saltation, sliding, rolling, suspension, and dissolved load; depositional processes, such as the spatial distribution of gravel, sand and clay as a stream enters a lake; and sediment transfer processes, ...

This Flash animated slide show is an illustration of spit formation. It shows how longshore currents pass headlands, slow, and deposit entrained sediment. It also shows how river mud is deposited behind the growing spit which is eventually only covered with water during high tide. Plants begin to grow and thus stabilize the mud. Homes or tourist facilities are often built on sand spits. The user can ... Full description.

This USGS news press release describes how the combination of shoreline erosion, land subsidence, anthropogenic infuences, and sea level rise are resulting in the loss of land in South Louisiana. It also discusses the value of Louisiana's coastal wetlands in terms of oil and gas infrastructure, shipping, fisheries, hurricane protection, and waterfowl. Full description.

This site from the "The On the Cutting Edge" workshop series features a wealth of ideas, teaching examples and web-based resources that are useful for teaching undergraduate hydrogeology. Full description.

The United States Global Change Research Program (USGCRP) was created as a high-priority national research program to: address key uncertainties about changes in the Earth's global environmental system, both natural and human-induced; monitor, understand, and predict global change; and provide a sound scientific basis for national and international decision-making. Some of the global change issues ... Full description.

This project seeks to understand the long-term interaction of humans, their culture(s) and their environment in southwestern Colorado, USA, from A.D. 600-1300. The research employs agent-based simulation to examine various models for how farmers locate themselves and use resources on this landscape. Agent-based models allow researchers from many disciplines to study a system that is characterized ... Full description.
