A Study on Efficient Management Strategy for Soil Erosion
황정배,김남찬,임창인,강윤민 한국토양비료학회 2018 한국토양비료학회지 Vol.51 No.4
Soil value was estimated 26 trillion Korean won and recent climate change due to global warming is highly affecting soil erosion. Especially, about 10% of surface soil was annually eroded because of massive construction in Korea. Main purpose of this research was i) to investigate occurrence, mechanism, affecting parameters of soil erosion especially focused on wind erosion and ii) to conduct wind tunnel experiment for evaluating feasibility of dry fog system in stabilizing wind erosion. Result of wind tunnel experiment showed that wind erosion could be reduced about 22-38% after applying dry fog system. Two parameters, soil particle size and spreaded water drop size, are main parameters to affect efficiency of wind erosion stabilization and smaller water drop size is more effective to prevent wind erosion than soil particle size. In terms of wind erosion management, evaluation of soil erosion should be conducted for environmental impact assessment (EIA) when land usage is changed or massive construction was conducted. Since there is no evaluation form of soil erosion in EIA, not only soil erosion but also wind erosion evaluation should be included in the EIA. In addition, transaction of soil and rock open portal recycle system (TOCYCLE) could be utilized to recycle surface soil and consequently, prevent wind erosion and conserve value of soil. Overall, dry fog system is an effective technique for wind erosion preventing system and it could be combined with natural and/or artificial soil conservation system to enhance wind erosion prevention. Furthermore, policy and management system for preventing soil erosion should be thoroughly reviewed to make better soil conservation.

This present study describes an application of UV scanning spectrometer O4 data for retrieval of aerosol vertical profiles in Seoul during the measurement period that includes two Asian dust event days. The results show large variations of aerosol load in vertical and temporal scales. Large variations in aerosol were observed at 1 km in height during the daytime in the measurement period when the Asian dust events took place. The aerosol load, however, was found to be largest at the surface compared to those retrieved at the higher atmospheric layers. The results also clearly identified the diurnal patterns of aerosol vertical distributions. The aerosol load was high in the morning and noon whereas it was low in the afternoon. This study demonstrates that UV scanning spectrometer observations of the oxygen dimer can serve as a potential method for determination of atmospheric aerosol vertical distributions and optical properties.

This study’s purpose is to establish the water quality improvement measures of the Nakdong River water system by determining pollutant sources and causes of the Nakdong river basin subwatershed (standard watershed). For this purpose, the water quality data of the inflow river according to the characteristics of the watershed are acquired for the eight dams of the Nakdong river system (Sangju, Nakdan, Gumi, Chilgok, Kangjeong-Goryung, Dalsung, Hapcheon-Changryung, Changryung-Haman) and obtained all the data necessary to identify the pollution sources. After identifying the current status and causes of pollution sources in the Nakdong River basin subwatershed (standard watershed), we selected priority to reduce pollutant load on subwatershed and improve water quality. 본 연구의 목적은 낙동강 수계 소유역(표준유역)별 오염원 발생 현황 및 원인을 파악한 후 소유역 오염부하량 삭감 및수질개선 우선순위를 선정하여 낙동강수계의 수질개선대책을 수립하는 데 있다. 이를 위해 낙동강수계 8개 보(상주·낙단·칠곡·구미·강정고령·달성·합천창녕·창녕함안)에 대하여 유역별 특성에 따른 유입하천의 수리·수질 자료를 확보하고, 유역내 점·비점오염원 파악에 필요한 제반 자료를 취득하여, 낙동강 수계 소유역(표준유역)별 오염원 발생 현황 및 원인을 파악한 후 소유역 오염부하량 삭감 및 수질개선 우선순위를 선정하였다.

The objective of this study was to propose the best methodology for estimating soil organic carbon stocks during environmental assessment for development projects. We compared three methodologies which were developed by Korea Environment Corporation(2010), Korea Forest Research Institute (2006), and Jin-Hyun Jung (1998). We found that the methodology developed by Jin-Hyun Jung (1998) shows the worst performance and the methodology of Korea Forest Research Institute (2006) does not reflect a variety of soil types and land use characteristics shown in development project plans. Therefore, we propose that the methodology developed by Korea Environment Corporation (2010) is the most reasonable one because it is internationally accepted and used for local governments to make the inventory of greenhouse gases as well as to set up its reduction strategy.

Recently, soil has been recognized as a crucially important resource that even can change the quality of life. Also, recent studies have gradually mentioned the importance of assessing soil impact induced by development plans and projects. In this study, after detailed soil assessement items were selected from our national environmental policies and international agreements, they were tested for the long-term dam construction planning in order to ensure more suitable implementation of strategic environment assessment(SEA). We found that soil resources can be impacted by diverse factors such as soil erosion, soil organic matters, soil moving, soil biodiversity, and others. Such detailed factors are found to be overlapped with the pervious EIA factors. Accordingly, additional studies would be required for finding out more reasonable connection between assessment factors during any SEA progress.
