How to Simulate the Future of a Watershed

University of Wisconsin: Water Sustainability and Climate

Using a tool similar to a computer game, Melissa Motew is peering into the future. Motew is a modeler. She uses computers and mathematics to simulate ecosystems and make sense of nature.

Her task is to shed light on what the Madison area’s environment could be like by the year 2070 and what this might mean for human well-being—how much food could we grow, how well could the land withstand floods and will we have clean lakes yet?

“We want to track what’s happening through time, so we can understand all of the changes,” says Motew.

The steps the article outlines are helpful: (1)start with stories, (2)simulate the system, and (3)ask what-if questions.
