  • Long-Term Estimation on Nitrogen Flux in the Yamato River Basin Influenced by the Construction of Sewerage Treatment Systems
    AHW32-P08 JpGU-AGU Joint Meeting 2020 Long-term Estimation on Nitrogen flux in the Yamato River Basin Influenced by the Construction of Sewerage Treatment Systems *Kunyang Wang1, Shin-ichi Onodera1, Mitsuyo Saito2, Yuta Shimizu3 1. Graduate School of Integrated Arts and Science, Hiroshima University, 2. Faculty of Environmental Science and Technology, Okayama University, 3. National Agriculture and Food Research Organization The quantification of the nitrogen discharge in water were most important indicators of the water environment in coastal area because these processes are related to the transport of large nutrient loads. The nitrogen pollution sources of the surface water environment are divided into point source pollution and non-point source pollution according to the different spatial distribution (Niraula et al. 2013; Lee et al. 2010). Nonpoint source nitrogen pollution is a leading contributor to world water quality impairments. (Steffen et al 2015). Sewage treatment system can significantly reducing pollutant emissions by multiple methods. The construction of sewage treatment systems does not happen overnight, it is divided into two parts: construction of sewage treatment plant and laying of underground pipelines into buildings. Especially for plumbing system, it is a long process. During this period, non-point source pollution from urban areas will be gradually transformed into point sources. Yamato river is a very important river in west Japan. It has a watershed area of 1067 square kilometers, covering almost half area of Nara prefecture. These have 5 sewage treatment plant in the watershed, 3 of them are located in Osaka Prefecture and others are in Nara Prefecture. These sewage treatment plants were successively constructed and put into use between 1974 and 1985.

  • Some Characteristics of Heavy Rainfalls in the Yamato River Basin Found by the Principal Component and Cluster Analyses
    Extreme Hydrological Events: Precipitation, Floods and Droughts (Proceedings of the Yokohama Symposium, July 1993). IAHS Publ. no. 213, 1993. 75 Some characteristics of heavy rainfalls in the Yamato river basin found by the principal component and cluster analyses M. KADOYA & H. CHIKAMORI Disaster Prevention Research Institute, Kyoto University, Gokasho, Uji, Kyoto 611, Japan T. ICHIOKA Sogochosasekkei Co., Ltd., Umedakita building, Shibata 1-8-15 Kita-ku, Osaka 530, Japan Abstract In this paper, characteristics of spatial distribution of heavy rainfalls causing floods in the Yamato River basin located in the Kinki district are examined by applying the techniques of both principal component and cluster analyses. The result of the principal component analysis shows that rain gauge stations in this basin can be arranged into eight groups from the common characteristics of rain storms. On the other hand, the result of cluster analysis differs slightly from the former, but supports it in the practical sense. Finally, the correlations of flood peak discharges at Kashiwara with 12-, 24-, and 48-hour maximum rainfalls averaged over a basin are examined. The result shows that the flood peak discharges have strong correlation with areal 12-hour rainfalls, especially with those in new urbanized areas along the main channel. INTRODUCTION Clarifying the characteristics of heavy rainfalls is the fundamental importance in the planning of flood control or the design of river structures. In this paper, the Yamato River basin located in the Kinki district is chosen as an objective research basin, and the relation between characteristics of heavy rainfall in the basin and flood peak discharges at Kashiwara is examined by applying the techniques of both principal component and cluster analyses to the rainfall data obtained in the basin.

  • Buraku Mondai in Japan: Historical and Modern Perspectives and Directions for the Future*
    Buraku Mondai in Japan: Historical and Modern Perspectives and Directions for the Future* Emily A. Su-Ian Reber** INTRODUCTION Arguments: An Overview The current state of legal, political, and sociological affairs in Japan con- stitutes an unfit stage for the eradication of discrimination against burakumin and the improvement of socioeconomic conditions among burakumin. First, federal law affords no protection to victims of discrimination1 : no anti- discrimination law exists, and access to certain government documents that can alert prospective employers and marriage partners to one's family lineage is not adequately restricted.2 Second, the limited nature of debate on buraku mondai constrains the possibility of a democratic and resourceful solution to the problem. Two opposing political organizations dominate the discourse regarding buraku mondai. Moreover, many people in Japan believe the best remedy for prejudice and discrimination is to ignore these problems. Third, the form of political redress regarding buraku mondai ironically propogates, while in other ways counters, discrimination against burakumin. Single bu- raku organizations, varying by community, but most often the Buraku Kaihi D6mei, or Buraku Liberation League (BLL), have been delegated almost full control over the administration of government-sponsored programs for bura- kumin. The BLL (nearly exclusively) offers the available relief to victims of * Portions of this Note have appeared in the March 1998 issue of the JoURNAL OF DOwA-MoNDAI [20 DOwA-M ONDAI KENKYO (JouRNAL OF DOwA-MoNDAi) 45 (1998)].

  • Modeling of Water Quality in Tidal River Network in Osaka, Japan
    Journal of Water and Environment Technology, Vol.13, No.3, 2015 Modeling of Water Quality in Tidal River Network in Osaka, Japan Masayasu IRIE, Tomo YAMAGUCHI, Shuzo NISHIDA, Yusuke NAKATANI Department of Civil Engineering, Division of Global Architecture, Graduate School of Engineering, Osaka University, 2-1 Yamadaoka, Suita, Osaka 565-0871, Japan ABSTRACT An urban tidal river network is one of the most difficult targets to simulate the flow and water quality in various kinds of water areas because the model must simulate both the vertical feature of the intrusion of sea water and the horizontal feature of water quality that is affected by human activities. In this paper, we determine the applicability of a three-dimensional flow and water quality model when reproducing the process of water with high concentrations of nitrogen, phosphorus and other constituents flowing through an urban tidal river network. We applied a three-dimensional model to Neya River, its tributaries and its downstream rivers in Osaka. The model can simulate well the vertical stratification of temperature and salinity near three river mouths, the mixing process of two different sources of water originating from Yodo River, and Neya River and its tributaries, the longitudinal profiles of chemical oxygen demand (COD), dissolved oxygen (DO), total nitrogen and phosphorus. Calculated water levels in the upstream area of Neya River system, however, are not coincident with the observations. A 3D water quality model, which is a potent tool in ocean and lakes, proved to be a versatile enough tool to simulate complicated and tidal urban river networks. Keywords: Neya River, three-dimensional water quality modeling, tidal river, urban river network, water quality INTRODUCTION Most rivers flowing through large cities have been influenced by drainage water and loadings after human water usage.
