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 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.
