An integrated EIA tool was developed to analyze present and future environmental quality status of Youngwol Basin using ArcView and FEMWASP. All the input data and computational results were prepared and graphically displayed on the basis of ArcView. FEMWASP and ArcView were integrated using the command "system.execute" in script of Avenue. Modeling items were inserted in the GUI of ArcView. The modeling result showed that the water quality of the proposed Yougwol Lake would be at the stage of eutrophication. The developed system can be applied to the water quality management of drinking water resources to set up the regulatory acts and project plan of governmental policy.

We investigate the groundwater distribution and chemical characteristics for 3 or 5 districts every year and make the hydrogeologic map on a scale of 1:50,000. We draw the hydrogeologic digital map based on "The Handbook for the Drawing and Management of Hydrogeologic Map" which was published by MOCT and KOWACO in 1998. But, the Stiff diagram and well's notation are difficult to be presented in the digital map using the commercial Arcview GIS tools. So we develop the script file with Avenue language to represent them in Arcview GIS tool. At first, we design the database for the chemical analysis result of groundwater and well identification, and make the program code with Avenue language to display them on the digital map. And next we test the usefulness of the program code. As a result, we find that the script file is very useful for drawing the symbols and diagrams in hydrogeologic digital map using ArcView GIS.

An integrated sewer management system was developed for the analysis of sewer flow and for optimal operation of sewer works using ArcView and SWMM. SWMM and ArcView were dynamically linked together using Avenue in order to construct user-friendly management system. The developed system was applied to a residential area in Choonchun city to verify its utilities. All the relevant field data were analyzed on the basis of developed system, and the modeling of sewer flow was implemented using MET, RUNOFF, TRANSPORT in SWMM. As this system can provide comprehensive prediction of flow and pollution profiles, it could serve as a tool not only for optimal management, but also for decision support system to examine the efficiency of planning and implementation of sewer projects.

Flood inundation analysis system using GIS has been developed to simulate inundation in airport drainage areas. The model developed in this study has been synthetically presented and constructed the preprocess for database construction and input data preparing through a graphic user interface, GUI system and the postprocess processing graphically output resulted in mainprocess analysis model linked GIS(ArcView/Avenue). The mainprocess analysis model was simulated in real phenomenon caused by inflow of storm sewer system by simulation flooding due to backwater effect and surcharged flow in storm sewer system by simulating interaction coupling the overland flow analysis model and storm sewer system analysis model. In the future, the flood inundation analysis system developed in this study will be a great contribution to systematic decision-making for establishing the flood-mitigation management and facilities improvement plan to flooding damage in airport.

The developed system was applied to a residential area in Choonchun city to verify its utilities. All the relevant field data were analyzed on the basis of developed system, and the modeling of sewer flow was implemented using RUNOFF, EXTRAN, TRANSPORT in SWMM. This system is now in the process of connection to the management system of watershed and surface environment in order to develope an integrated environmental management system. Futhermore, this system will be a critical part of overall control system of sewer works including sewer line and wastewater treatment plant. As this system can provide comprehensive prediction of flow and pollution profiles, it could serve as a tool not only for optimal management, but also for decision support system to examine the efficiency of planning and implementation of sewer projects.

토양유실량을 산정하기 위한 모델로 Universsal Soil Loss Equation(USLE)가 전 세계적으로 가장 많이 사용되고 있다. USLE 모형은 농경지에서 면상침식(Sheet erosion)과 세류침식(Rill erosion)을 모의할 수 있는 시험포단위 모형(Field-scale)으로 농경지에서 유실된 토양이 하류 하천으로 얼마나 흘러 들어가 하류 수계의 탁수발생과 이에 따른 수질악화에 얼마나 기여하는지, 즉, 유역단위의 토양유실량을 평가하는데 이용될 수 없다. 이러한 단점을 극복하기 위하여 Sediment Assessment Tool for Effective Erosion Control (SATEEC) ArcView 시스템이 개발되어 사용되고 있다. SATEEC ArcView 시스템은 USLE모형의 입력자료와 DEM만으로 유역면적에 따른 유달률을 산정하여 유역에서 유실된 토양이 얼마만큼 하류로 유달되는지를 모의할 수 있으며, 유역 경사도에 의한 유달률도 산정할 수 있어 지형적인 특성을 좀 더 다양하게 분석 할 수 있게 개발 되었다. 그러나 ArcView는 출시한지 오래되어 사용자가 많지 않고, 프로그램상의 오류가 많고, 대용량의 데이터 처리가 가능한 64비트 운영체제에서는 설치가 불가능한 단점이 있다. 또한, ArcView의 프로그래밍 언어인 Avenue는 클래스를 정의한다거나 상속을 한다거나 하는 문법을 제공하지 않기 때문에 객체지향 언어로 보기에는 부족하다고 할 수 있다. 또한, 최근의 ArcGIS 기반의 많은 모델들이 서로 연계하여 사용하고 있으나, Avenue는 기타 다른 프로그래밍 언어와 연계하여 사용하기가 쉽지 않은 단점이 있다. 그러나 최근 ArcGIS 버전들의 프로그래밍 언어인 Python은 간결하고 확장성이 좋으며, 다른 언어와의 연계가 쉽다. 또한, ArcGIS 10.x버전부터 제공되는 arcpy 모듈은 사용자와의 접근성이 매우 향상되었다. 따라서 SATEEC ArcView 버전을 ArcGIS 10.1 기반의 Python 으로 재개발하여 기존의 불편한 접근성과 대용량 데이터의 처리가 불가능했던 부분을 개선하였다.

In order to develop a spatial information system that can efficiently manage various subsurface data and produce information in a proper form for a user, we established a database of the well cores and built 3-D shapes that visualize the subsurface objects such as wells, ore bodies, tunnels, and mine cavities. We also made analysis tools available for three-dimensional ore bodies constructed here, such as vertical cross-section generator and mass computing tool. This system was developed by coding Avenue, a scripting language incorporated in ArcView, which is a commercial GIS software. Using the system, it is expected that users can make fast and accurate analysis and interpretation through real-time queries and by contemplating various objects in 3-D perspective.

A GIS-RUSLE system has been developed to estimate soil losses from where individual fields on a hillslope using the RUSLE in a GIS environment. The GIS-RUSLE adopts a user interface and a user can use the drop-down menus to define the inputs and get the calculated results. The input data are generated from Arc/Info and ArcView GIS and the factors of the RUSLE are provided from ArcView Avenue. Examples of the GIS-RUSLE applications are presented.

In Korea, MOCT and KOWACO published a standard for lineament map drawings, "The Handbook for the Drawing and Management of Hydrogeologic Map" in 2003. According to this guideline, hydrogeologic and related thematic maps should include characteristics of groundwater quality and quantity. These maps are generally drawn with ArcView GIS 3.x software. The activities of well notation on groundwater level map and Stiff diagram drawings on groundwater quality map require a great deal of efforts because hundreds or thousands of well data, water level data and hydrogeochemical data are produced through many kinds of investigations. As well, lineament density map is very important to survey and explore groundwater in a deep aquifer. In this study we developed some modules for well notation, Stiff diagram drawings, and lineament density value calculation with Avenue$^{TM}$ script and it was revealed that they can be very useful and easy for drawing groundwater thematic maps.

A web based watershed and sewer management system was developed for the analysis of stormwater runoff and sewer flow, and for optimal operation of sewer works using ArcView and SWMM. SWMM and ArcView were dynamically linked together using Avenue and Visual Basic in order to construct user-friendly management system. The developed system was applied to Choonchun city to verify its utilities. All the relevant field data were analyzed on the basis of developed system, and the modeling of runoff and sewer flow was implemented using RUNOFF and TRANSPORT blocks in SWMM. This system was connected to the management system of surface and subsurface environment management system in order to develop an integrated environmental management system. Futhermore, this system will be a critical part of overall control system of sewer works including sewer line and wastewater treatment plant. As this system can provide comprehensive prediction of flow and pollution profiles and analytical tool equipped with Web-GIS, it could serve widely as a tool not only for optimal management, but also for decision support system to examine the efficiency of planning and implementation of sewer projects.
