Computing for Sustainable Water

The Computing for Sustainable Water (CFSW) project is one of three water-related projects selected to run on the IBM World Community Grid. This project evolved from the UVa Bay Game as a very detailed, simulation-only model of the Chesapeake Bay. Not a game, the CFSW model simulates over 34,000 spatial areas; 1,069 river and stream segments; and 4 million households over a 20-year period on a monthly basis. The model explores the potential outcomes of various practices ("Best Management Practices") on the nutrient loads reaching and impacting Bay health.

The CFSW project launched publicly on April 17, 2012 and is available for execution on the World Community Grid, a network of nearly 2 million contributed computers. The model runs in the background of these volunteered computers using otherwise idle cycles and not interfering with the owner's applications. There will be over 1.3 million experiments distributed to computers on the World Community Grid, each requiring approximately 7 hours of computing time. If this work were done on the UVa Cross-Campus Computing Grid (XCG), it would take about 90 years to complete; with the power of the IBM World Community Grid, it will require less than one year.

The UVA Bay Game

The UVa Bay Game® is a large-scale participatory simulation of the Chesapeake Bay Watershed in the United States. Players in each of the seven sub-watersheds take the roles of crop farmer, livestock farmer (beef, dairy, pork, and poultry), land developer, waterman (crab fishing), and various regulators. At each round of game play, decisions are input and the model is advanced. Based on the results, players can modify their decisions for subsequent rounds. The Bay Game has been used in college classrooms, among public officials, and with large U.S. industries that are becoming increasingly aware of the environmental impact of water quality and quantity on their future operations.
