Effects Of Land Cover Change On Water Quality In Urban Streams At Two Spatial Scales, Sonia Singh, Heejun Chang

International Journal of Geospatial and Environmental Research

This study examines the relationships between land cover change and water quality change in three urbanizing watersheds in the Pacific Northwest region of the United States: Burnt Bridge Creek, Salmon Creek, and the Tualatin River. All three watersheds have had many of their water quality parameters exceeding Total Maximum Daily Loads as required by their state’s environmental agencies in the past decades. By using the National Land Cover Datasets classified by the United States Geological Survey (USGS) for 1992, 2001 and 2006 and water quality data for a period between 1991 and 2010, this paper aims to examine whether changes …
