This research was conducted to investigate the influences of the solifluction soil and amount of flow on the stream water quality of the Bukhansan National Park from March to october, 2002. The average pH of stream water was higher than that caused by solifluction soil. The average electrical conductivity of upstream water was about 2.1~2.8 times lower than that of downstream water. Linear regression analysis showed that pH and amount of anion($Cl^-$, ${NO_3}^-$, ${SO_4}^{2-}$) of stream water were very significantly correlated with those at the caused by solifluction soil. Structures for erosion control along both sides of stream channel should be designed in order not to influence upon solifluction soil and stream water quality.

This research was conducted to investigate the influences caused by solifluction soil on the physicochemistry of stream water quality at the riparian area four points in the northeastern part of the Bughansan National Park from March to May of 2001. The average pH of stream water was higher than those in the caused by solifluction soil. The average electrical conductivity of upstream water was about 0.8~1.7 times lower than those in the caused by solifluction soil, but the average electrical conductivity of downstream water was about 1.6~3.8 times higher than those in the caused by solifluction soil. Therefore, these results showed that the water quality of downstream was worse than that of upstream. Twelve factors including the physicochemistry on the stream water and caused by solifluction soil were analyzed by spss/pc+ for the data collected from during March to May of 2001. pH of stream water was very significantly correlated with pH and electrical conductivity at the caused by solifluction soil. And the electrical conductivity of stream water was very significantly correlated with electrical conductivity and the amount of cation($Na^+$, ${NH_4}^+$, $Mg^{2+}$) at the caused by solifluction soil.

This study aims to clarify the effect of forest management practices(thinning and pruning) on soil physical properties and water quality to get the fundamental information on the facility of purifying water quality after forestry practices. Rainfall, throughfall, stemflow, soil and stream water were sampled at the study site which consists of Pinus rigida in Jinju National University Experimental Forest for 4 years from Mar. 1, 2002 to Nov. 30, 2006. Averaged tree height of the management site increased by 1.6m, compared to the value of the non-management site in Pinus rigida. Increment of averaged D. B. H. at the management site showed 4.2cm more in Pinus rigida compared with that at non-management sites. Mesopore ratios (pF2.7) and total porosities of A layer soil at the management site increased more than those at the non-management sites in both stands. Otherwise, soil bulk density resulted in being reversely. Water qualities of throughfall, stemflow and buffered soil water were influenced more positively by the management practice. The average electrical conductivity of stream water was $32.9{\mu}S/cm$ within the range of non-polluted stream water.

Monitoring techniques for afro-ecological environments were studied, Hydrologic and ecological components in conjunction with water quality were monitored in the Balkan watershed. The hydrologic monitoring program consists of four water level gauging stations along creeks and stream at the watershed having 26.5 km2. Stage - storage relationship of reservoir, rainfall amount of the watershed, and rating curve of the stream gauging stations were established. Soil type, land use, hydrologic soil group, population and economic activities within the watershed were surveyed. Water quality data from the streams were sampled weekly and chemical analysis was conducted. Temporal variations of water quality were investigated and water quality map of each reach of stream was made to identify spatial variations. Seasonal and spatial variations of vegetation densities along stream in the watershed were investigated using grid, Density variations of insect species such as arthropod, flying insect, spider spices, rice insects were also monitored to determine seansonal surveying density. These monitored data will be used to develop monitoring techi%ues and afro - ecological environment models.

This research was conducted to establish the conservation strategy of stream water quality by analyzing the factors influenced on stream water quality in the northeastern part of Mt. Bughansan National Park from July 1998 to October 2001. The number of visitors resulted in the significant increase of electrical conductivity, which affected on pollution of the stream water quality. According to the multiple regression analysis, the pH of the stream water was related to dissolved oxygen and temperature of water at the 1% significant level. The electrical conductivity of the stream water was related to number of visitors, amount of $K^+$ and ${NO_3}^-$, total amount of ions, percentages of $Cl^-$ and $Na^+$ caused by solifluction soil at the 1% significant level. The anions($Cl^-$, ${NO_3}^-$ and ${SO_4}^{2-}$) of the stream water were related to number of visitors, electrical conductivity, air temperature, hardness, amount of ${NO_3}^-$, ${SO_4}^{2-}$, total ions, percentage of $Cl^-$, ${NO_3}^-$, ${SO_4}^{2-}$, amount of $Ca^{2+}$ caused by solifluction soil at the 1% significant level. To prevent the pollution of stream water in the northeastern part of Mt. Bughansan National Park, it is recommended that the number of visitors in the park should be managed and rehabilitated rapidly by measure to eco-friendly during the spring season.

To understand runoff Phenomena in Jeju island, some streams are monitored automatically about stream stage, and water quality in Jeju Provincial Water Resources Management Office. Rating curves for stream discharge are reviewed. Stream stages respond very quick to some rainfall events, and parameters influencing runoff phenomena such as landuse, soil condition, preconditoned rainfall, and vegetables will be studied. A few thousand to ten thousand ml/day are estimated from 6 permanent streams in Jeju island.

최근 물환경에 관련된 광범위한 문제들을 해결하기 위한 대안으로 유역관리의 관심이 증대되고있는 시점에서, 본 연구는 금호강 유역을 모니터링하기 위한 환경정보의 구축과 소유역 단위의 환경특성이 하천 수질에 미치는 영향을 분석하였다. 소유역 단위의 환경특성을 분석하기 위한 GIS 데이터베이스는 축척 1:25,000의 지형도, 정밀토양도, 토지이용도, 10m 해상도의 DEM, 도로망도, 수계망도, Landsat TM 영상에서 산출된 식생지수(NDVI), 강우량, 그리고 RUSLE 모형에 의한 토양유실량으로 구성되었다. 소유역 단위의 환경특성과 하천 수질간의 상호관련성을 분석한 결과에 따르면, 유역의 도시화 또는 산업화에 관련된 주거 상업지역, 공업지역, 도로지역에 관련된 변수들은 BOD, COD, SS, T-N, T-P의 수질자료와 음(-)의 상관성을 가지는 것으로 분석되었다. 이와는 달리, 자연환경상태와 관련된 산림피복과 식생상태 변수들은 수질자료와 양(+)의 상관성을 가지는 것으로 분석되었다. 그러나, 농업적 토지이용과 농약 및 비료사용량, 토양유실량은 수질자료와 유의한 상관성을 가지지 않는 것으로 나타났다.

이 연구는 계류에 설치되어 있는 사방공작물이 계류수질에 미치는 영향을 구명함으로써 계류복원을 위한 사방공작물의 설치방향을 정립하기 위한 기초자료를 제공하기 위하여 수행하였다. 북한산 우이동 계곡에서 사방공작물이 설치되어 있지 않은 상류지역의 평균pH는 6.32(5.73~6.90)로 사방공작물을 통과한 계류인 하류지역의 평균pH[6.53(6.25~6.82)]와 유사하였으며, 상류지역에서의 평균용존산소량은 10.3(9.6~10.6) mg/L로 사방공작물을 통과한 하류지역에서의 평균용존산소량 10.2(9.9~10.4) mg/L와 유사하였다. 평균전기전도도는 상류지역에서는 $62.2(40.3{\sim}89.5){\mu}S/cm$, 하류지역에서는 $63.9(32.6{\sim}120.4){\mu}S/cm$로 유사하였고, 평균음이온총량은 상류지역에서 4.51(2.56~4.29) mg/L, 하류지역에서 5.94(3.43~7.98) mg/L로 유사하였다. 산청군 홍계계곡에서 평균pH는 상류지점에서 6.89(6.61~7.12), 하류지점에서 6.86(6.50~7.10)으로 유사한 값을 나타내었고, 평균용존산소량은 상류지점에서 12.2(11.6~12.6) mg/L, 하류지점에서 11.9(11.5~12.3) mg/L로 유사하였다. 평균전기전도도는 상류지점에서 $32.7(31.4{\sim}34.3){\mu}S/cm$, 하류지점에서 $33.4(31.6{\sim}34.6){\mu}S/cm$로 유사하였고, 평균음이온총량은 상류와 하류지점에서 1.0(0.1~2.2) mg/L로 매우 유사한 값을 나타내었다. 북한산 우이동계곡과 산청군 홍계계곡을 대상으로 사방공작물이 설치되어 있지 않는 자연계류와 사방공작물이 설치된 하류지역에서의 계류수질을 분석한 결과 상하류간의 수질은 큰 차이가 나타나지 않았다. 사방공작물은 시공과정에서 계류수질에 영향을 미치므로 계류복원을 위하여는 각 개별 사방공작물에 대하여 시공 전후의 계류수질변화과정을 시계열적으로 심도 있게 연구할 필요가 있다.

A study was conducted to investigate the seasonal changes in water quality of watershed in the Agricultural Environment Promotion Zone. Samples collected were 12 GW (ground water), 2 IW (irrigation water), 2 SW (stream water) in An-Dong City, 4 GW, 6 IW, 11 SW in Young-Yang Gun, and sampling was conducted separately during dry and rainy season. In the ground water, EC and ionic species, except pH, were higher than those in stream water, and especially $NO_3-N$ concentration exceeded the limitation of drinking water. Concentration of ions decreased as the sampling depth was far from the soil surface. During a rainy season, the concentrations of $NO_3-N$ and K in the stream water were slightly higher than those during season. COD was lower during dry season in Yong-Yang, while the trend was contrasted to An-Dong. These results suggest that ground water was polluted by fertilization and compost while streamwater was polluted by loss of soil and organic during the rainy season. Principal chemical components related with changing water quality were EC, $NO_3^-$, Ca, Mg, Na, $Cl^-$, $Cl^-$, $SO_4^-$ in ground water, whereas $NH_4-N$, K, Mg, $Cl^-$, $SO_4^-$ in stream water.
