지난 2008년 11월 중앙정부와 팔당수계 7개 시 군은 수질보전과 더불어 지역사회의 개발을 위해 2008년 '수질오염총량관리제도'(이하 오총제)의 의무제 도입을 합의하였다. 오총제의 의무제 도입에 따라 수행되어야 할 각 유역별 토지이용 특성 분석 및 배출되는 오염물질의 정도의 명확한 규명이 이루어지지 않고 있기 때문에 유역관리의 방향 설정이 어려운 상황에 놓여있다. 이에 본 연구는 기존의 농도규제에서 좀 더 과학적 수질관리 기법인 총량관리 개념의 '수질오염 총량관리제도'의 도입에 따라 효율적이며 과학적인 소유역 관리를 위해, 토지이용과 오염물질 유출 간의 관계를 파악하고자 하였다. 대상유역은 앞서 언급한 7개 시 군의 각각 주요 하천 3개소를 선정하여 총 21개소를 2009년 6월부터 12월까지 7개월 동안 월 3회씩 BOD 및 COD를 모니터링하였다. 또한 그 유역을 전수조사를 통해 토지이용도를 조사하였다. 연구결과를 요약하면, 토지이용에 따른 산림지역이 가장 많은 지역은 가평군 남양주시로 나타났고, 도시 및 주거지가 많은 지역은 여주군, 용인시 및 이천시이며, 농지가 많은 지역은 양평군 여주군으로 나타났다. COD 및 BOD의 배출 정도는 농지와 도시 및 주거지가 많은 지역에서 높은 수준(p<$0.05^*$)으로 나타났으며, 특히 도시 및 주거지가 많은 유역에서 그 정도가 더욱 심각한 것으로 나타났다. 이에 반하여 임지의 토지 이용률이 증가할수록 BOD 및 COD 평균농도는 감소하는 것으로 나타났다(p<0.001).

In this study, we performed 8 times of water quality sampling and continuous measurement of flow to identify wastewater flow characteristics for wastewater treatment basins of Namyangju city. The field survey has been conducted 6 times in dry weather period and 2 times in wet weather period. Each survey conducted 24-hr water quality sampling in the interval of 2-hr. From the analysis of flow data and water quality data, the following conclusions can be drawn. For Namyangju-1 station, which represents residential and commercial mixed area, flow rises early in the morning before office-going hour and moves up and down within narrow range, and lasted after office-leaving hour, resulting from continuous commercial activity. In case of Namyangju-5 station representing community and Namyangju- 6 station representing residential area, the flow immediately falls down after rising early in the morning and later rises again at the office-leaving hour, and arrives at peak flows around late evening. In the analysis of wastewater characteristics for weekdays and weekends, without landuse types the flow rate of weekends is higher than that of weekdays because it reflects population, being not contributed to generate wastewater during the working hours of weekdays, stay home and produce wastewater for weekends period.

Over- and under-excavation are factors that increase construction cost of tunnels, which makes management essential. Total stations have been used for tunnel surveying because GNSS is difficult to use in tunnels. However, it takes much time to acquire data using total stations. In this study, a total station was integrated with a 3D laser scanner and used for tunnel surveying in Namyangju-si, Gyeonggi-do. The scanning total station reduced the work time compared to the conventional method. Furthermore, reports were effectively generated for overbreak and underbreak for each section and compared with the design. In addition, we could analyze both the cross section and scanned area effectively by using the scanning data. This method can improve the efficiency of tunnel surveying work by combining the advantages of a conventional total station and a 3D laser scanner.
