A two dimensional explicit finite difference circulation model with appropriate boundary condition is developed to solve the linear shallow water equations. The finite difference grid is a staggerd distribution of variables and computed vertically-integrated flow per unit width in a computational domain. The proposed circulation is applied to SANG KWAN reservoir. Computed results are as follows; 1) It is easy to understand mass conservation that parameter took discharge per unit width. 2) In numerical results, it is represented the flow pattern very well and demonstrative purpose. 3) It is considered wind effect in order to explain physical behavior in reservoir.

This study was carried out in order to estimate the domestic sewage quantities-qualities from combined sewer in Iksan and Hameol. To investigate the domestic sewage quantities-qualities from combined sewer, sample were collected 2 times during this study period at ten points. Flow rate analysis demonstrates a major morning and evening peak between 08:00∼10:00 and 19:00∼22:00, respectively. The concentrations of BOD were in the range of 23∼340㎎/ℓ and 28∼318㎎/ℓ, respectively. The highest concentrations of BOD occurred in the point 1. The concentrations of suspended solids were in the range of 18∼330㎎/ℓ and 13∼85㎎/ℓ, respectively. The pollution loading runoff after a rainy season decreased compared to that made before the rainy season. Comparisions with data for second survey show lower than first survey, from domestic sources, of many dilute water often regarded as having a mainly groundwater origin.

This study formed a scenario to improve a water quality by expecting and analyzing a water quality of Jeollabuk-do Seomjingang water system, so calculated a result. As a result, it was analyzed that a water quality is improved at 15.32 % of the maximum BOD, 7.17 % of T-N, and 62.86 % of T-P according to domestic and livestock cut amount by reinforcing discharge water of sewage disposal plant and improving pollutant management plans. It was analyzed that supplementing various cut plans such as establishment of efficient cut plans, plans to decrease pollution loading amount, plans to increase sewage disposal efficiently, pollutant decrease through an expansion of sewage disposal area, and energy recovery from animal dung of Total Pollutant Load Management System, and developing a study on more efficient improvement plans of water quality by considering natural increase and economic development are efficient in an improvement in a water quality. 본 연구는 전라북도 섬진강수계의 수질을 예측 분석하여 수질을 개선하는 시나리오를 구성하여 결과를 산출하였다. 결과적으로 공공하수처리시설의 배출수 관리강화 및 오염물질 관리 개선과 국내 축산계 감소에 따라 수질이 최대 BOD 15.32 %, T-N 7.17 %, T-P 62.86 %로 개선된 것으로 분석되었다. 효율적인 감축 계획수립, 오염부하량 저감계획, 하수 처리 효율 증대 계획, 공공하수처리시설 확대로 인한 오염물질 감소 및 총 오염 부하 동물 배설물 에너지 회수 등 다양한 삭감계획을 보완한 것으로 분석되었다. 자연증가 및 경제발전을 고려한 수질 개선 계획에 대한 연구개발은 수질 개선에 효율적이다.

The entire duration of the research work was from December-2000 to July-2002. Site measurement were conducted during various season, in a dry season(December), in rainfall, in seed-sowing time and also collecting data from the rural public organizations related to water management was done and examined during the mid of research work. Generally, the Dong Jin River watershed contains small three Creeks, KoBu, DongJin(including JeongEup and ChilBo, WonPyong). It was further divided into 32 sub-watersheds which comprises of further 5, 18, 9 watersheds in the creeks respectively. Inflow loading to the river was calculated from measurement of general water quality and quantity and these field surveys were made thrice times in agricultural drainage channels, where fertilizers and pesticides leaching from the surface have an direct effect for the deterioration of the several creek and river. Estimation of contaminant loading has been done by using unit loading based on the notification No. 1999 - 143 of the Ministry of Environment. Most of estimated loading data reported during the research work were slightly higher when compared with the notification of the Ministry but they do not have any significant effect. It was assumed that sub-watersheds have considerable field survey loading data, which were affected due to non-point source pollution load as compared to point source. For investigation of surface rainfall ranging from .50㎜ during non-farming or .10 rainfall on the period of farming, BOD loadings in the field during farming showed slightly higher levels in comparison with discharge loadings, T-N also showed the similar trend as discussed earlier.

Nonpoint source pollution(NSP) arises due to agriculture activity and it is quite an extensive and complicated problem in order to control and has received a great deal of concern during the recent years, whereas point source are known to originate from an estimated volume of contaminant discharged from a distinguishable source. Extensive research work have been conducted and presented in the past with regard to the various characteristics of watershed on Dong Jin River(DJR), however there are certain drawbacks of existing survey for determining important polluting sources, distribution features of pollutants and estimated load of the organic and nutrients from the creeks. Unfortunately, investigation for loadings originating due to agricultural drainage was not satisfactory, although the regional consideration for DJR across Kim Je Field(KJF) as an agricultural area receives a reasonable source point in the agri-pollution management. Therefore it was necessary to carry out a thorough investigation into the diffuse sources resulting, to form the pollution-developing estimation and to evaluate the output roperties and determining various factors in the generation of non-point pollution. Eventually, this research work would serve as an useful tool for the development of predictive pollution management for DJR. Non-point sources in the present work were classified as municipal non-treated sewage water discharged into the river, loadings through agricultural drainages in the dry/wet field and inadequate treatment of wastewater generated from livestocks. The entire duration of the research work was from December-2001 to July-2002. Site measurement were conducted during various season, in a dry season(December), in rainfall, in seed-sowing time and also collecting data from the rural public organizations related to water management was done and examined and examined during the mid of research work. Similarly, domestic wastewater loadings due to population was based on area unit, as City, Country, Up, Myon, Dong, Ri. The Dong Jin River watershed contains small three Creeks, KoBu(KB), DongJin(DJ, including JeongEup(JE) and ChilBo(CB), WonPyong(WP). It was further divided into 32 sub-watersheds which comprises of further 5,18,9 watersheds in the creeks respectively. The results obtained from research work are presented as follows. Animal productions have marked differences in the rate of pollutant loadings reported in the following sequence: DJ(only CE)>WP>CB>KB, in a case of Korean cow and milk cow. However, it was revealed that WP creek became significantly higher than any other livestocks. According to statistical data for land use, rice field(369.0㎢) and forest(378㎢) have much occupation prior to dry paddies(125.0㎢), residential land(32.0㎢) and others(5.0㎢). Especially, rice fields receives 2.5∼3 times than dry paddies in size.
