Many studies have been conducted to develop new technologies for arsenic removal and to reveal the levels of arsenic and other chemicals in rivers, lakes and ground waters. However, there are few studies dealing with such compounds in the total water system of the city, and the way of management of these compounds in the water system. Because the occurrence of these hazardous compounds, which are geological origins, is almost impossible to control, it is very important to manage these compounds in the water system. In this research, it was revealed that the risk of arsenic in the water treatment system of S city in Japan. As a results, the parameters such as Q in river and E260 in drinking water treatment plant is proposed as a new indicator with simple and rapid method for controling arsenic level.

In this study we developed a turbidity management system to support the operation for effective turbid water management. The decision-making system includes various models for prediction of turbid water inflow, effective reservoir operation using the selective withdrawal facility, analysis of turbid water discharge in the downstream. The system is supported by the intensive monitoring devices installed in the upstream rivers, reservoirs, and downstream rivers. SWAT and HSPF models were constructed to predict turbid water flows in the Imha and Andong catchments. CE-QUAL-W2 models were constructed for turbid water behavior prediction, and various analyses were conducted to examine the effects of the selective withdrawal operation for efficient high turbid water discharge, turbid water distribution under differing amount and locations of turbid water discharge. A 1-dimensional dynamic water quality model was built using Ko-Riv1 for simulation of turbidity propagation in the downstream of the reservoirs, and 2-dimensional models were developed to investigate the mixing phenomena of two waters discharged from the Andong and Imha reservoirs with different temperature and turbidity conditions during joint dam operation for reducing the impacts of turbid water.

The Korea has high population density, so the precipitation per capita is only one tenth to world average. The water resource in Korea is insufficient. But the leakage in the water distribution system is about 25%, and it is lower than other countries where water utilities are managed well. The pipelines' management also is getting worse because the leakage in the pipelines lower the ground density surrounding pipes. So, managing the leakage in the water distribution system is very important in the view of increasing the water resources and doing the efficient management of the pipeline system. Accordingly this study aimed to conduct a cause-analysis with scientific approaches considering key local factor related to water loss of distribution system and derive better performance indicators which are able to evaluate the real state of water loss management reasonably. Also this research aimed to develop a methodology capable of judging condition of infrastructure of water distribution system.

A decision support system DSS-WQMRA (Decision Support System-Water Quality Management in Rural Area) was developed to help regional planners for the water quality management in a rural basin. The integrated model DSS-WQMRA, written in JAVA, includes four subsystems such as a GIS, a database, water quality simulation models and a decision model. In the system, the GIS deals with landuse and the location of pollutant sources. The database manages each data and supplies input data for various water quality simulation models. the water quality simulation model is composed of the GWLF( Generalized Watershed Loading Function), PCLM(Pollutant Loading Calculation Module) and the WASP5 model. The decision model based on mixed integer programming is designed to determine optimal costs and thus allow the selection of managemental practices to meet the water quality criteria. The methodology was tested with an example application in the Bokha River Basin, Kyunggi Province in Korea. It was proved that the integrated model DSS-WQMRA could be very useful for water quality management including the non-point source pollution in rural areas.

금강의 중ㆍ상류부에 위치한 인공호수인 대청호 유역의 경우, 최근 급격한 인구증가와 물자생산, 그리고 이들의 결과로 인한 각종 오염물질의 증가로 수질보전과 관리에 심각한 문제가 야기되고 있으므로, 이에 대한 집중적인 수질관리가 요구된다. 이들 문제를 해결하기 위하여 지난 수년간 많은 연구가 수행되었지만 근본적인 해결의 실마리를 찾지 못하고 있다. 뿐만 아니라, 현재 수행되고 있는 수질관리가 미흡한 것으로 나타나고 있어 이를 보완할 새로운 관리기법의 도입이 시급히 요구되고 있지만 이에 대한 체계적인 기술축적과 자료 및 경험의 부족으로 많은 어려움을 겪고 있는 실정이다. 본 연구는 WASP5 모형을 이용하여 대청호의 수질을 해석하고 GIS와 연계시켜 수질관리시스템을 구축함으로서 효율적이고 과학적인 수질관리가 이루어지도록 하는데 그 목적이 있다. WASP5 모형을 대청호의 실측치와 비교하여 모형의 보정과 검증을 수행하였고, 수질관리시스템 구축을 위한 GIS와의 연계는 ArcView의 Avenue를 이용하여 구성하였다. Avenue를 통한 다양한 메뉴 구성 및 이를 통한 모의수행은 사용자 요구나 편의에 맞게 손쉽게 처리할 수 있도록 구성하였다. 따라서, GIS 환경하에서 실제적이고 효율적인 수질관리 뿐만 아니라 장래수질의 예측도 가능하기 때문에 대청호 이외에 다른 유역에 대한 활용성도 매우 높을 것으로 판단된다.

Sapkyo Lake Watershed occupies about 19.3% of total area of Chungnam Province, and it is necessary to make a plan of counter-measure for the maintenance of public waterbody sound as well as to ensure water resources due to urbanization and industrialization in this area so densely populated and excessively developed. Conventionally water quality management has been enforced by concentration-based system which is not considered the carrying capacity of receptors, hence there are no proper measures for the prevention of an excessive pollutant load over a waterbody. So even though emission sources abide by the conventional permission regulation, then the quantity of wastewater is increased continuously and encountered water shortage to use finally. Therefore this research focused on the review of introduction of total water quality management system in Sapkyo Lake watershed to maintain public waterbody sound and to ensure water resources. By doing this research in introduction of the system in advance, it can contribute to establish the methodology on systematic water quality management. Also the application of this system in Sapkyo Lake watershed can promote the sustainable development of the area by harmonizing the environment and regional economy ultimately.
