본 연구는 금호강 유역에 분포하는 생태관광자원의 지리적 특성을 밝히고, 생태관광자원의 교육적 활용방안을 모색하는 것이다. 금호강 유역이 생태관광자원을 파악하기 위해 금호강 유역에 관련된 여러 문헌들을 검토하여 생태관광자원을 유형별로 정리하였다. 생태관광자원은 지형 및 지질자원, 식물군락지, 야생동물서식지, 문화역사적 자원, 생태자원을 이용한 지역이벤트 등으로 구분하여 지역적 특성을 고찰하였다. 교육적 활용 방안은 뉴질랜드 생태관광의 실태를 참고하여 다음과 같이 제안한다. 생태관광은 지역주의의 주도적 활동으로 이루어져야 하며, 주민의 능력에 맞게 인원을 제한하여 보다 효과적인 교육이 이루어지도록 해야 하며, 생태자원을 효과적으로 관찰하기 위해 환경친화적인 탐방로와 생태학습관을 건립하고, 수준 높은 안내게시판을 설치하며, 계절에 관계없이 지속적인 활동이 이루어지도록 계절별로도 다양한 프로그램을 준비해야 하겠다.

A study on the water pollution of Gumho river by the relationship between physio-chemical conditions and water quality level by phytoplankton was examined at 6 sampling positions during the period from April 21 to August 11, 1982. Examination of physio-chemical water analysis such as temperature, pH, DO, BOD and biological analysis has shown 1. The average for Gumho river was 6.2 - 7.2 of pH, 2.6 - 9.4 mg/l of DO, 28.8 - 122.4 mg/l of BOD. 2. The phytoplankton identification in this survey period showed, Cyanophyceae is 7 genera 13 species, Bacillariophyceae 11 genera 32 species and Chlorophyceae 17 genera 27 species. 3. The results of biological water analysis were as follows: Banyawol was from oligosaprobic to $\beta$-mesosaprobic. Dongchon and Gumdan was from $\alpha$-mesosaprobic to $\beta$-mesosaprobic, 3rd gongdan was from oemesosaprobic to $\beta$-polysaprobic, Paldal was $\beta$-polysaprobic and Gangchang was repolysaprobic. 4. To appear dominant algae there were Microcycstis, Oscillatoria, Anabaena, Melosira, Nitzschia and Synedra.

The goal of this study is to forecast the trend of stream quality and to suggest some policy alternatives in Gumbo river. It used the five different monthly time series data such as BOD, COD, T-N and EC of the nine of Gumbo River measurement points from Jan. 1998 to Dec. 2006. Water pollution is serious at Gumbo2 and Palgeo stream measurement points. BOD, COD, T-N and EC data are analyzed with the exponential smoothing model and the trend is forecasted until Dec. 2009.

The purpose of this study is to analyze present condition and users' behavior on waterfront in local city. To analyze the current physical statues and behavioral issues, 3 cities including Jinju city(Nam river), Ulsan city(Taewha river), and Dae-gu city(Gumho river) has chosen as research areas, the questionnaire and field survey were conducted in research areas focusing on post occupancy evaluation. In this study, it was found that main behaviors of waterfront were rest and exercise and overall satisfactions of waterfront were related to the decision-making for revisitation. However, unsatisfactory physical factors of waterfront were the position and number of facilities related to the behaviors such as rest, exercise, and bicycle riding. Especially, most unsatisfactory factor was the inadequate lighting in respect of intensity of illumination and position although much people had been used each waterfronts at nighttime. In conclusion it was thought that it was necessary to reinforce the program related to culture and leisure such as public performance and to establish infrastructure related to life-time sport and various outdoor exercise for waterfront activation.

본 연구에서는 낙동강-금호강 합류부의 생태유량을 산정하기 위해 2차원 수치모형 River2D를 이용하여 가중가용면적(WUA, Weighted Usable Area)을 계산했다. River2D 모형의 검증을 위해 HEC-RAS모의결과와 비교하여 최적 매개변수를 결정했다. 그리고 낙동강의 우점종인 피라미와 갈겨니를 대상으로 낙동강과 금호강의 유량을 변화시키며 가중가용면적을 모의했다. 유량-WUA/A의 그래프로부터 생태유량을 산정한 결과, 낙동강의 경우 $33.3m^3/s{\sim}40.0m^3/s$, 금호강의 경우 $3.60m^3/s{\sim}4.32m^3/s$를 낙동강-금호강 합류부의 생태유량으로 결정하였다. 결정된 생태유량을 적용하여 낙동강 본류의 하상준설 이후 피라미와 갈겨니의 가중가용면적을 계산한 결과, 가중가용면적이 약 1/9로 감소했다. 그리고 준설 이후에 잉어에 대한 가중가용면적은 피라미와 갈겨니에 대한 것보다 2~3배 더 큰 것으로 계산됐다.

This study aims at the calculation of a variation of flow characteristics of main channel for tributary inflow in river junction. So this study was analyzed the variation of flow depth and velocity in main channel for a change of inflow degree. For this purpose, FLDWAV model are carried out for variations of $30^{\circ}$, $60^{\circ}$ and $90^{\circ}$ tributary inflow at junction. Results show that velocity ratio(V1/V3) increases and flow depth ratio(H1/H3) decreases for discharge ratio(Q1/Q3) of upstream and downstream when degree increases in junction. And FLDWAV model was applied at a real river junctions. Selected area is a junction of Gumho river and Sin stream. Results show that pattern is similar to a virtual channel.

Analyzing the water quality biologically by the biotic index ($\beta$) of Beck-Tsuda method, for four sites of the water system of Namcheon River which reaches a length of 19.5km and flows through the kyungsan-town and Namcheon-myun in Kyungsan-gun of the suburbs of Taegu and extends to the Gumho-river on the lower, the results are summarized as follows: 1) An indicator species collected from the water system of Namcheon River comprises 78 species. Among them, 27 species are intolerant species and 51 species are tolerant species to water pollution. 2) The water of 2 sites, Weondong-bridge, Sanjeon-iron bridge was clearly water, oligosaprobic zone. The water of Youngdae-bridge was slightly polluted water, $\beta$-measosaprobic zone. But the water of Maehoildong bridge was severely polluted water, polysaprobic zone. 3) The Namcheon River was mainly polluted with sewage from the kyungsan town, with industrial wastes and products from many factories surviving the town. 4) The pH wate system of Namcheon River was alkalescent. 5) The map showing a class of water quality analyzed biologically was also prepared for each site of the water system of Namcheon River, Kyungsan. 6) It is requested that a waste water disposal plant should be established near Youngdae-bridge and Maehoildong-bridge respectively.

Long-Term Hydrologic Impact Assessment (L-THIA) was modified to improve runoff and pollutant load prediction for Korean watersheds with changes in land use classification and event mean concentration produced from observed data in Korea. The L-THIA model was linked with SCE-UA, which is one of the global optimization techniques, to automatically calibrate direct runoff. Modified L-THIA model was applied to Gumho River Basins to analyze spatial distribution of nonpoint source pollution. The results of model calibration during 1991~2000 and validation during 1981~1990 for direct runoff represented high model efficiency of 0.76 for calibration and 0.86 for validation. As a results of spatial analysis of nonpoint source pollution, the BOD was mainly loaded from urban area but SS, TN, and TP from agricultural area which is mainly located along the stream. Modified L-THIA model improve its accuracy with minimum imput data and application efforts. From this study, we can find out the L-THIA model is very useful tool to predict direct runoff and pollutant loads from the watershed and spatial analysis of nonpoint source pollution.
