Delaware River Basin Project
 Delaware River Basin Project Home Page Links to individual projects: Modeling Urban Expansion in the Philadelphia Metropolitan Area; A Cellular Automata Approach Historical land-use data from the twentieth century was used as input to the SLEUTH land-use change model, a Cellular Automata model developed by Keith Clarke at the University of California at Santa Barbara, to produce projections of urban expansion in the Philadelphia metropolitan area. Twentieth-Century Land Surface Changes in the Delaware Water Gap Basin, a GIS Snapshot Approach Methods of integrating land-surface data and measuring change with time are being tested on historical land use/land cover data of the Delaware Water Gap watershed area in Pennsylvania. |
Urban Growth ModelingThe Clarke Urban Growth model (see "Project Gigalopolis") is being used together with the Philadelphia temporal mapping database to create foreseeable scenarios for urban growth planning purposes. Growth projections for the entire Philadelphia metropolitan area are planned to be calibrated on Beowulf cluster.Modifications to the Clarke model are being made at Mid-Continent Geographic Science Center (MCGSC) to allow experimentation with various urban growth factors for input to the model.
