  • For the assessment of climate change impacts for the Byeongseong stream, CGCM 3.1 T63 is selected as future climate information. The projections come from CGCM used to simulate the GHG emission scenario known as A2. Air temperature and precipitation information from the GCM simulations are converted to regional scale data using the statistical downscaling method known as MSPG. Downscaled climate data from GCM are then used as the input data for the SWAT model to generate regional runoff and water quality estimates in the Byeongseong stream. As a result of simple sensitivity analysis, the increase of CO2 concentration leads to increase water yield through reduction of evapotranspiration and increase of soil water. Hydrologic responses to climate change are in phase with precipitation change. Climate change is expected to reduce water yields in the period of 2021-2030. In the period of 2051-2060, stream flow is expected to be reduced in spring season and increased in summer season. While soil losses are also in phase with water yields, nutrient discharges (i.e., total nitrogen) are not always in phase with precipitation change. However, it should be noted that there are a lot of uncertainties in such multiple-step analysis used to convert climate information from GCM-based future climate projections into hydrologic information.

  • Field surveys were conducted from May 2016 to October and from April to October 2017 in Tributary Region of Middle Stream of the Nakdong River. The survey was carried out at 66 sites including Young-gang 11, Naeseong-cheon 21, Wi-cheon 16, and Gam-cheon 9, Byeongseong-cheon 9. As a result of investigation, 474 taxa in total ; 99 familly, 288 genera, 421 species, 4 subspecies, 39 varieties and 10 forma. Among them, 5 Korean endemic plants, 7 rare plants, 31 taxa were listed as Floristic Target Species in Korea. Naturalized plants was confirmed 73 taxa, their Urbanization Ratio 22.7%, and naturalization ratio 15.4% in the investigated area. The Life form(Dormancy form) review results as follows ; Therophytes 159 taxa, Hemicryptophytes 91 taxa, Hydrophanerophytes 68 taxa, Geophyte 52 taxa, Nanophanerophytes 35 taxa, Megaphanerophytes 32 taxa, Microphanerophytes 25 taxa, Chamaephytes 12 taxa, and Epiphyten 1 taxa.

  • Inhabitants make a specific cultural landscape in various ways according to his culture. In this paper, I consider the characteristics of cultural landscapes distributed in Sangju. I divide Sangju-City Area owing to physical criteria(relief and drainage basin}, appreciate them according to human criteria(administrative district of Joseon Period, dialects, periodical market area} and classify into 6 small regions: (1) Nakyang Region is the traditionally central place based on alluvial plain marginal to Byeongseong stream and Dong stream, and on hills of Sabeol. (2) Nakdong Region is the traffic center which the water transport of Nakdong river and the land transport of Yeongnamdaero cross each other. (3) The upstream region of Byungseong stream is the agricultural region connected with Nakyang Region. (4) Jungmo Region is a intermontane basin where grape cultivation using its specific climate flourish. (5) Wharyeong Region is a mountainous sightseeing district based on the beautiful scenery and Gyeonwhueon's remains of Sogni mountains and Yongyu valley. (6) Hamnyeong Region is the district of Goryeonggaya realm where 3 whites(cocoon, dried persimmon, rice) are abundant.
