하이퍼센서 정보를 이용한 태화강지역의 비점오염원 분석 = Analysis of Non-Point Pollution Sources in the Taewha River Area Using the Hyper-Sensor Information

다국어 초록 (Multilingual Abstract)

In this study, multi-image information for the central Taewha River basin was used to develop and analyze a distribution map of non-point pollution sources. The data were collected using a hyper-sensor (image), aerial photography, and a field spectro-radiometer. An image correction process was performed for each image to develop an ortho-image. In addition, the spectra from the field spectro-radiometer measurements were analyzed for each classification to create land cover and distribution maps of non-point pollutant sources. In the western region of the Taewha River basin, where most of the forest and agricultural land is distributed, the distribution map showed generated loads for BOD(kg/km²×day) of 1.0 - 2.3, for TN(kg/km²×day) of 0.06 - 9.44, and for TP(kg/km²×day) of 0.03 - 0.24, which were low load distributions. In the eastern region where urbanization is in progress, the BOD, TN, and TP were 85.9, 13.69, and 2.76, respectively and these showed relatively high load distributions when the land use was classified by plot.
