St. Charles County, a suburb of St. Louis, Missouri, has undergone significant urban expansion in recent decades. Rapid urban sprawl in the Dardenne Creek watershed within the county has had a profound influence on surface runoff. The AA. examined the patterns of land use/land cover (LULC) change in this watershed using Landsat TM/ETM+ imagery in 1982, 1987, 1991, 1999 and 2003. Calibrated with the observed hydrological data in 2003, a Long-Term Hydrologic Impact Assessment (L-THIA) model was used to evaluate the effect of LULC change on surface runoff. Model simulations suggest >70% increase in average direct runoff in the watershed from 1982 to 2003, and the runoff increase is highly correlated with urban expansion
