This study investigates the processes of the "Production of Nature" and the preservation and exploitation of nature in the local festival. The recent discussions in tourism geography address the neoliberalization of nature with its political-ecological interpretation. Yangyang-gun has been one of the main regions that have made efforts to make salmon back to the streams. Also, the Yangyang Salmon Festival was organized to celebrate and symbolize the successful restoration of nature. In fact, however, the festival focuses on the commercialization of salmon. Moreover, it is hard to consider Namdaecheon as the successfully restored ecosystem for salmon. As the returning number of salmon has not significantly increased and the festival itself has not been successful to attract many tourists, the local people show declining interest on the conservation of salmon. Contrast to the catchphrase of the festival to emphasize the conservation of nature and restoration of ecosystem, there are still many hurdles that jeopardize returning of salmon. This controversy leads diverse actors into conflict over the conservation of salmon and Namdaecheon. The players in the dispute encompass local people, local and national governments and international organization. Nature appropriated for ecotourism is selectively defined, used and emphasized by the interests of agencies at multiple scales. The findings of this study show that the concept of "Produced Nature" is more useful than intrinsic or original perspective on nature as long as we try to understand the commercialization of nature that is appropriated for the repertoire of local festival.

일반적으로 자갈하천의 하상에는 여울, 소의 연쇄 구조(Riffle-pool sequences)가 발생한다. 여울은 수심이 얕아 유속이 빠른 부분이고 소는 수심이 깊어 유속이 느린 부분에 해당한다. 여울과 소의 연쇄구조는 모래하천에서는 보이지 않는데, 여울에서는 빠른 유속으로 인하여 하상의 조립화가 진행되며, 반대로 소에서는 하상이 세립토로 구성된다. 그리고 여울은 하도의 경사에 따라 발생하며, 유속의 빠름과 느림에 따라 크게 평여울과 급여울로 구분할 수 있다. 본 연구의 대상하천인 양양 남대천은 국내에서는 보기 드물게 개발이 거의 되어있지 않으며 조사대상 구간인 어성전(법수치) 계곡을 포함한 양양 남대천 상류 약 0.4 km은 산지하천 구간으로 비교적 자연하천의 상태를 유지하고 있다. 본 연구는 자갈하천의 구간에서 연속적으로 발생하는 여울, 소를 대상으로 하상경사, 하상재료, 수심, 유속 등 물리적 특성을 조사하였다. 이 구간에서의 나타난 여울 구간은 11개소로 구분할 수 있으며, 급여울이 시작되는 구간에서부터 여울과 소는 반복적인 형태로 나타났다. 하상경사는 평여울 구간에서 0.0011-0.0057, 급여울 구간에서 0.0143-0.0201로 나타났다. 하상재료는 $D_{50}$의 경우 평여울 구간에서 3.66-4.63 mm, 급여울 구간에서 3.61-4.63 mm로 나타났다. 이와 같은 연구는 자연하천이 갖는 여울, 소 연쇄구조의 물리적 특성을 이해하고, 자연형 여울, 소를 조성하거나 복원 시 설계를 위한 기초자료로 활용될 것으로 기대된다.

The Yangyang Pumped Storage Power Plant is being constructed by Korea Electric Power Corporation in Namdae-Chun River, Korea. The Yangyang Pumped Storage Power Plant has 1000MW capacity with upper reservior, lower reservior, hydrauric tunnel and underground power plant facilities. But NGO(Non Governmental Groups) and residents are worried about the power plant construction because of some problems, as follows. (1) Namdae-Chun River is principal salmon returning river in Korea. (2) Namdae-Chun River is main water supply source of the Yangyang country. So, brief explanation of Environmental Impacts Assessment executed by Korea Electric Power Corporation, main environmental impacts and countermeasures will be introduced.

에듀테인먼트는 교육(education)과 오락(entertainment)의 합성어이다. 교육적인 내용을 놀이와 접목시킨 것을 말한다. 최근 하천개발은 치수적인 면에 개발과정을 넘어서 친수적인 면, 환경적인 면을 부각시켜 보다 질높은 삶을 살아가는 방향으로 발전하고 있다. 치수사업에 있어서도 과거의 제방중심의 사업에서 보다 다양하고 진보된 대책의 개발과 적용이 이루어지고 있다. 이러한 치수적인 안정을 기반으로 친수적인 면이 부각되면서 보다 접근성이 용이하고, 친수적인 하천의 개발이 지속적으로 이루어지고 있다. 최근의 지역축제로 성공적인 하천 축제로 강원도 양양군 연어축제(남대천), 경상북도 봉화은어축제(내성천)등이 있다. 이러한 축제들은 주요내용이 물고기를 잡는 체험과 관계기관의 적극적인 참여와 관리로 전국의 관광객들이 찾는 축제로 발전하고 있다. 일반적으로 이러한 축제들은 대상어종에 대해 설명하고 있으며, 물고기를 잡는 체험으로 진행되고 하천에 대한 스토리를 접목시키지만, 하천변 개발로 이루어지는 것은 부족한 실정이다. 본 연구에서는 하천개발에 있어 다양한 소재를 접목시켜 친수적 하천개발에 교육적 요소를 결합하여 스토리 텔링기법으로 하천을 개발하는 방안을 제안하였다.

Standard length (SL) and gonadosomatic index (GSI) of Plecoglossus altivelis were investigated from March to October 2007 in Seomjin River and streams flowing to the East Sea, Korea. Water temperatures were $17{\sim}23^{\circ}C$ during the spawning season, which ran from late September to early November in Seomjin River and early August to mid-October in streams flowing to the East Sea. The GSI and HSI variations of ayu population in Seomjin River increased earlier than in populations in streams flowing to the East Sea with similar variation in water temperature. Histological study of ovaries showed that the start of spawning of P. altivelis in Seomjin River was later than in streams flowing to the East Sea. Overall, fecundity increased with increase in SL and not by site specificity. The SL of P. altivelis increased as the river scale increased. Mean length of specimens from Seomjin River (river length: 223.86 km, river area: $4,911.89km^2$) was $194{\pm}15.3mm$, from Osip Stream (55.76 km, $393.78km^2$) $185{\pm}15.5mm$, from Yangyang Namdae Stream (54 km, $474.08km^2$) $142{\pm}11.8mm$, and from Joosoo Stream (21.1 km, $141.47km^2$) $136{\pm}16.7 mm$.

In August 2022, even though flood damage occurred in the metropolitan area due to heavy rain, drought warnings were issued in Jeolla province, which indicates that the regional drought is intensified recent years. To cope with regarding intensified regional droughts, many studies have been conducted to identify spatial patterns of the occurrence of meteorological drought, however, case studies of spatial clustering for water shortage are not sufficient. In this study, using the estimations of water shortage in the Han River Basin in 2030 of the Master Plans for National Water Management, the spatial characteristics of water shortage were analyzed to identify the hotspot areas based on the Local Moran's I and Getis-Ord Gi^*, which are representative indicators of spatial clustering analysis. The spatial characteristics of water shortage areas were verified based on the p-value and the Moran scatter plot. The overall results of for three anayisis periods (S0(1967-1983), S1(1984-2000), S2(2001-2018)) indicated that the lower Imjin River (#1023) was the hotspot for water shortage, and there are moving patterns of water shortage from the east of lower Imjin River (#1023) to the west during S2 compared to S0 and S1. In addition, the Yangyang-namdaecheon (#1301) was the HL area that is adjacent to a high water shortage area and a low water shortage area, and had water shortage pattern in S2 compared to S0 and S1.

태백산맥의 중심부인 중앙산맥을 경계로 하여 동쪽에 위치하고 있는 영동지방은 서쪽으로 태백산맥이, 동쪽으로는 동해바다와 바로 인접해 있는 지리적인 특성으로 인해 지역적 특성이 매우 강하며, 이에 따라 국지적 기상현상이 계절적 변화와 함께 빈번히 발생하는 지역이다. 2002년 태풍 루사가 영동지방을 강타했을 때 영동지방의 대표도시인 강릉지방에서는 기록적인 폭우(일최다 강수량 870.5mm)가 내렸으며, 그 다음해인 2003년 매미 뿐 아니라 최근발생하고 있는 국지적인 호우로 인한 영동지방의 피해가 지속적으로 발생하고 있다. 이러한 상황에서도 수문학적 관점에서의 홍수유출 및 강우특성에 대한 분석 및 연구가 거의 전무한 실정이다. 이것은 대상지역인 영동지방 특히 삼척오십천 유역내의 강우 및 수위 관측소가 간헐적으로 분포되어 있으며, 강우 및 수위(유량)자료의 확보가 용이하지 않기 때문으로 사료된다. 본 연구에서는 동해 강릉 기상레이더(2010.5 동해기상레이더 교체 이전)의 레이더강우자료와 지상강우 및 수위(유량)자료를 활용하고, 집중형 모형에 비해 더 정확한 강우-유출 현상 모의가 가능한 것으로 분석되고 있는 분포형 모형(Vflo$^{TM}$)을 이용하여 분석하였다. 먼저 영동지역 중 첫번째로 삼척오십천유역에 대한 유출분석을 하였으며, 과거 큰 홍수피해를 준 태풍 루사 매미 및 최근의 호우사상을 대상으로 하였다. 본 논문에서 연구된 삼척오십천유역에 대한 유출특성 분석을 시작으로, 양양남대천 강릉남대천에 대한 유출특성에 대한 연구를 추가로 수행된다면, 영동지방의 국지적 기상현상(집중호우 및 태풍)으로 인한 홍수피해를 최소화 할 수 있는 방재측면에서의 홍수대응방안을 마련하는데 본 연구내용을 충분히 활용할 수 있을 것이다.

We analyzed the aquatic insects and stomach contents of chum salmon (Oncorhynchus keta) fingerings which were collected at Namdae stream in Yangyang. A total of 6 orders, 25 family, and 52 species of aquatic insects have been found in the study area. The majority of prey eaten by chum salmon fingerlings was Diptera, which occupied 91.7% of prey items by number and 40.9% by wet weight. The food items from juvenile salmon stomachs were matched with living organisms in the river. Therefore it seemed that there was no food selectivity of juvenile chum salmon in Namdae stream. The stomach contents of masu salmon fry showed a similar pattern to the fingerlings of chum salmon. This result will provide information on the carrying capacity of Namdae stream for chum salmon.

The ichthyofauna and fish community structure were investigated at eleven stations in Namdae stream, Yangyang during April, 2004 and March 2005 monthly. During the surveyed period thirty five species belonging to fifteen families were collected. Dominant species in number was Triboblodon hakonensis (relative abundance : 27.9%) and subdominant was Zacco koreanus (15.0%). There were five Korean endemic species including Rhynchocypris kumgangensis. Eleven species including Pungtungia herzi are first recorded in this study. There are stabilized fish community structure with dominant species R. kumgangensis in upstream, Z. koreanus and Z. platypus in midstream and T. hakonensis in downstream respectively. But, it is very worried the change of ichthyofauna in foreseeable future because of pumped storage power station construction in midstream.

The water qualities of Namdae-stream, Yeongok-stream and Sacheon-stream were examined, by using physicochemical factors, trophic status and epilithic diatoms from May 2008 to February 2009. The physicochemical water qualities of three streams were, except for some construction areas and sites of downstream, generally good, having less concentration than BOD of $2\;mg\;L^{-1}$. As for the sites of downstream, there were ongoing pollution such as graduation of nutrients in Namdae-stream and Sacheon-stream, due to salinity of seawater and topographical feature of the closed estuary. The examination of trophic status of Namdae-stream showed mesotrophic status in all the sites. Also, eutrophication was in progress as from the upstream to the downstream of Yeongok-stream, and Sacheon-stream showed eutrophic status in all its sites. As a result of the biological water quality assessment, Namdae-stream, excluding the downstream site, came out to be $\beta\sim\alpha$-oligosaprobic, and biological water quality was good, having TDI less than 50. Some construction sites and downstream site of Namdae-stream are $\beta$-mesosaprobic, and with the TDI over 70, the biological water quality assessment came out to be polluted. Yeongok-stream is $\beta\sim\alpha$-oligosaprobic, and its biological water quality is good, having TDI less than 40. Sacheon-stream, excluding the upstream site on May 2008 and February 2009, is $\beta\sim\alpha$-mesosaprobic, and its TDI over 70 shows that it has been polluted. The correlation analysis showed a high correlation in both DAlpo and TDI. Also, biological assessment of water quality (DAIpo, TDI) showed higher correlation with TSI rather than BOD.
