  • Coccoid green algae collected from March to November 2015 from 79 freshwater ecosystem sites throughout South Korea, including lakes, ponds, swamps, streams, and rivers, were identified using light microscopy. A total of 218 taxa were identified, among which 11 were new species records in Korea; these 11 species were found at four sites (Hanagang River, Chukdong reservoir, Chukdong fishery, and Deokjin reservoir). The new species recorded were Fotterella tetrachlorelloides, Trochiscia naumannii, Keriochlamys styriaca, Placosphaera opaca, Siderocystopsis fusca, Siderocelis oblonga, Siderocelis estheriana, Pachycladella umbrina, Pachycladella zatoriensis, Crucigenia mucronata and Scenedesmus sempervirens.

  • Estuary lakes constructed for agricultural water resources development projects have encountered eutrophication problems. Natural water purification function of wetland is considered for nutrient removal from inflowing stream. A constructed wetland was designed and installed for pollutant loading abatement in estuary lake Koheung. Combined pond-wetland system was adopted. In this system primary and secondary ponds and six wetland cells were interconnected. Reed and cattail were selected for wetland vegetation and planted in the wetland cells. In this paper, design criteria of the pond-wetland system in temperate weather zone is presented.

  • Ten species of paramecia have been recorded up to the present , but there has been no report on paramecium in Korea. With the purpose of taxonomical study, paramecia were collected as materials at the several areas(ponds and streams) in Seoul from the first of March to the late of October , 1962. From the characteristics of the body-shape and the type and number of micronuclei, the six unrecorded species are identified on this paper as follows : Paramecium caudatum P.aurelia P.multimicromucleaturm P.bursaria P.trichium P.calkinsi

  • Studying on the shirpms produced out of the freshwater in Nam-hae Island , the four kinds of them were found as follows : 1. Paratya compressa (De Haan) 2. Neocaridina denticulata (De Haan) 3. Neocaridina denticulata koreana Kubo 4. Caridina leucostica Stimposon Among the said kinds of them, Paratya compressa and Caridina leucostica are to be listed for the first time in Korean shrimps fauna, and at the same time, Neocaridina denticulata and Neocaridina denticulata koreana were found distributed mostly in whole the rivers, lakes and ponds of this area.

  • In 2017, the freshwater algae were collected from reservoirs, small ponds, soil, and rocks in Korea. Eight taxa of Chlorophyta (Chlorophyceae and Trebouxiophyceae) have been newly reported in Korea. The unrecorded indigenous species were Chlorolobion braunii, Coelastrum pseudomicroporum, Coelastrum reticulatum var. cubanum, Monoraphidium nanum, Tetrachlorella incerta, Ecdysichlamys obliqua, Gloeotila scopulina, and Stichococcus jenerensis.

  • The objectives of this study are to develop a stormwater management system that would contribute to improving water circulation, recycling storm water and promoting biodiversity in urban areas, to apply the system in an actual site, and to verify its effectiveness in order to generate a stormwater management system applicable in Korea. This study reviewed former researches and case studies, categorized stormwater management system into pre-treatment, retention and infiltration phases, and analyzed the strength and weakness of the techniques by synthesizing unit techniques of each stage. As a result, the process of the stormwater management system includes the following phases: 1) a rubble filtration layer; 2) a retention pond; 3) a infiltration pond; and 4) a stormwater retention pool (recirculation and recycling). Then, an empirical study to design and create the generated system according to the features of a site and to verify its effectiveness was conducted. The future study direction is to verify the effectiveness of the developed stormwater retention and infiltration ponds. To this end, it is planned to perform hydrological monitoring using automatic measuring equipment and monitoring on habitat bases and the biota living on the base. Based on its outcome, the applied model would be refined and improved to develop an alternative stormwater management system that would allow to achieve the improvement of urban water circulation, increase of biodiversity and efficient use of water resources.

  • The place of South Weol Dynastys authorities exhumed in the region of KangChoWu, China lies adjacent to a stone ditch through which water streams crookedly, and a dark trough of stone pond in the north side. There is a sharply curved stone ditch and a crescent-shaped water entrance made by stones. The place was separated by using stone columns and stone walls. There is a beam of ditch, a crooked entrance, a flat bridge of slate, a stepping-stone, a sluice gate, and a crooked corridor. There are big and small artificial islands, and reinforcing stone drainage way in the palace pond recently exhumed at the building site for the pavilion of Hwang-Yong Temple in Kuhwang-Dong, Gyeongju city, Korea. There are four facilities assumed to be entrance and exits at four corners and an open space on which gravel was spread extensively. A narrow road and a middle road with indefinite curves at the south of Asukakyoseki exhumed by the first, second and third and two stone buckets which one is to fill with water and the other is to drain water off like fountain are there, and besides wave protecting dam and north pond and the part that water pass were excavated. Palace ponds that were extensively distributed at old residential cities are a general phenomenon of countries in eastern Asia. Anap pond of Silla and Gungnam pond of Baekje were in Kroea. We believe that Asutnkyoseki is on the extension. Although more investigations in the background of thought and the genealogical relation about the palace pond are required, it seems that an idea was surely received from China.
