The study by Heejun Chang, a geography professor in PSU's College of Liberal Arts and Sciences, and Janardan Mainali, a Ph.D. student in geography, was published online in the Journal of Hydrology in June. It was supported by a grant from the National Science Foundation.
The study used spatial data from the early 1990s through 2016 to examine seasonal water-quality trends in the Han River basin, the largest and most populous river basin in South Korea. The river had become synonymous with pollution as factories, farms and city sewer systems poured waste into its waters. But ahead of the 1988 Seoul Olympics, the government launched efforts to begin cleaning it up.
Study - Relationship - Water - Quality - Nitrogen
The study examined the relationship between water quality -- as measured by total nitrogen (TN), total phosphorus (TP), chemical oxygen demand (COD) and suspended soil particles -- and topography, population density, soils, and land cover such...
