This study identified the sedimentary environment of the abandoned paddy wetlands in the Jang-gumegi wetland in Yeongyang-gun through climate data and sediment grain size analysis. The analysis of climate data revealed that the annual mean temperature is a significant factor by potentially impact on the ecosystem and sedimentary environment in the study area. There was no statistically difference in annual mean temperature or annual precipitation between the two periods(A: 1997-2009, B: 2010-2022). However, during the seasonal mean temperature change, the annual mean temperature was higher in period B. The greatest amount of change occurred during the summer, and the results were statistically significant at the 5% level. In the analysis of sediment grain size, the average grain size is fine sand, average sorted is very poorly sorted, and the skewness were typical characteristics of river origin sediments. As a result of physicochemical analysis, it was found that soil acidification had been caused by suspended matter f lowing from ponds and valleys in the upper part of the wetland, and that salts and organic matter had accumulated. The results of this study can be used as basic data for the further research on the development process of abandoned paddy wetlands.

본 연구는 부산광역시・울산광역시・경상남도(이하 부・울・경)지역 상부소리에 사용되는 악기 유형별 공간 분포 특성을 분석하여 지역별 문화지역을 구분하였다. 연구결과, 부・울・경 지역 상부소리에 사용된 악기는 총 3개이며, 악기 없이 부르는 상부소리유형을 포함하여 소리 문화 지역을 총 4개로 구분하였다. 세부적으로, 북부평야지역은 주로 낙동강과 그 지류인 황강 유역의연속된 평야지역을 따라 상부소리에 북을 주로 치는 지역이 다수 분포한다. 서부산지지역은 핑경을 사용하는 문화가 주를 이루고있으며, 소백산맥 일대의 거창, 함양, 산청, 하동에서 나타났다. 동부산간 및 해안지역은 악기 없이 상부소리를 부르는 지역이분포하며, 일부 낙동강 유역에 해당하는 지역에서는 북을 사용하여 부르는 지역이 나타났다. 마지막으로, 중부 및 남부해안지역은주로 꽹쇠를 치며 부르는 지역이 분포하며, 일부 낙동강 일대와 가화천 일대에서는 북과 핑경을 이용하여 부르는 지역이 나타났다. This study analyzed the spatial distribution characteristics of the types of musical instruments used in the funeral songs in the Busan Metropolitan City, Ulsan Metropolitan City, and Gyeongsangnam-do (abbreviated as Bu-Ul-Gyeong) to classify cultural regions. As a result, a total of three funeral songs were used in the funeral songs of the Bu-Ul-Gyeong region, and a total of four sound culture regions were categorized, including the type of the funeral songs sung without musical instruments. In detail, the northern plains region is mainly distributed along the continuous plains of the Nakdong river and its tributary, the Hwang river basin, a large number of areas where drums are mainly used for the funeral songs. The western mountainous region is characterized by the Pingkyung culture, found in Geochang, Hamyang, Sancheong, and Hadong in the Sobaek mountains. The eastern intermontane and coastal region is characterized by the singing of the funeral songs without instruments, with some areas along the banks of the Nakdong river using drums. Finally, the central and southern coastal areas are mainly characterized by the use of the Kkwaenggwari, with some areas along the Nakdong river and Gahwacheon using the drum and Pingkyung.

This study analyzed the spatial distribution characteristics of songs for each type based on the data of the weeding songs recorded in the Gangwon region, so as to classify cultural areas. As a result, the areas of sound culture were divided into a total of six cultural areas, focusing on the eight typical types of weeding songs in the Gangwon region. To be specific, Short Deongeori Type is distributed in the northern Yeongseo region and connected to the adjacent Pocheon in the Gyeonggi province, and sound diffusion was made along the Chugaryeong Tectonic Valley and the Hantan River basin. In the central Yeongseo region, weeding songs such as Sangsa Type and Bangasori Type mainly appear and are mostly distributed in the plains of the southwestern area. On the other hand, in the southern Yeongseo region, Danheori Type is distributed in the neighboring cities and counties with Wonju and Hoengseog as centers of sound culture, while Arari Type appears in Jeongseon and Pyeongchang in the Taebaek Mountains region. In the northern Yeongdong region, Minari Type is mainly distributed in the plains around small streams. In the central Yeongdong region, Odokttegi Type and Minari Type are mainly distributed, and Gangneung is the center of sound culture for Odokttegi Type. In the southern Yeongdong region, Minari Type appears to some extent. However, it is adjudged that in this area, Ipmal Type with Uljin located in Gyeongsangbuk-do as the center of sound culture appears and sounddiffusion is made.

This study analyzed the changes of the Jang-gumegi wetland using multi-temporal aerial images, and proposed an objective method of delineating wetland boundaries. The result of the study indicated that the Jang-gumegi wetland were formed in paddy fields in the early 1900’s, and the number of households and paddy area continued to increase by the government’s 5-year plan for agricultural production enhancement and the baby boom thereafter. On the other hand, the study area gave up on agricultural production when the number of households decreased due to migration from rural to urban area after the 1980’s, and the fields have been abandoned since then. Meanwhile, the wetland boundaries were re-detected based on the location information by GPS and soil depth data and sediment samples were updated in the Jang-gumegi wetland. The soil depth between the regions was proportionated to the period of paddy cultivation, and the grain size of the sediment consisted mostly of clay, silt and partially sandy particles. This reflected poor drainage of paddy fields, and it indicated that the sediment supplied from the slope after fallow was deposited along a gentle slope. The derived result is expected to serve as a guideline for the establishment of preservation and management measures for abandoned paddy wetlands and a better methodology for wetland boundary settings.

In this study, the changes and characteristics of sedimentary environment in Geum River channel by opening gate of Sejong Weir were analyzed using aerial photos and drone images. Sedimentary landform was classified during the study period and it has been found that the changes of area in some classes such as mid-channel island of divided type, mid-channel island of undivided type, sand barrier, and sand island were larger than that of other classes. In addition, the characteristics of area changes of the sedimentary landform were analyzed in this study. As a result, it was determined that erosion and deposition of sediments in the river was depended on the increase of flow rate and velocity by the increase of precipitation particularly during the summer rainy reasons as well as typhoons, growth of vegetation, and efficiency of dam. The results can be used as data to identify the process of conserving endangered wildlife and restoring the naturalness of the river environment.

This study analyzed the characteristics of in-channel sedimentary environment changes in Hwang River basin of Hapcheon Dam downstream using multi-temporal aerial photographs. In particular, the study area was subdivided into five sections to detect recent changes in the riverbed since the construction of Hapcheon Dam. The results showed that the Hwang River basin has experienced a significant increase in the area of fluvial sedimentation sites(mid-channel islands and sand bars) by more than 56% between 2019 and 2022. This is partly due to the relatively lower river level in the Hwang River basin downstream of the Hapcheon Dam during the same period, which exposed some of the in-channel sand deposits, but also because fluvial sediments supplied by upstream and tributary rivers were deposited in addition to the existing mid-channel islands and sand bars, resulting in the growth of new sand bars around them. In terms of sections, A section was dominated by erosion during the whole period, B section was balanced between erosion and deposition, C section was dominated by deposition, D section was dominated by deposition, and E section was slightly dominated by deposition. The results of this study can be used as a basis for analyzing the effects of dam construction and discharge on the transport and deposition of river sediments, and for predicting changes in the sediment deposition sites in rivers lost to man-made structures in the future.
