Korea is about 70% of all country to mountain, and basin is consisted of various terrain, soil, vegetation, land use etc. because use land as intensive. Also, need basin hydrologic model that can analysis base outflow as well as outflow directly for calculation of discharge to establish irrigation plan. Inconvenient in use method and user interface offer side is causing by way that existing USGS WEASEL runs in PC Arc/Info, and ArcGIS with development of present GIS technology is applied in many fields offering convenience in analysis that use GIS. In this research, wished to develop suitable outflow parameter extraction system, For this, develop pre-processor and post-processor that effectively draw of hydrologic model input data from water resources DB through van example benchimarking, and developed input/output component of GIS base applicable to various hydrologic and water quality model.

The water quality model SWAT (Soil and Water Assessment Tool) was used in combination with GIS, Arc/Info and GRASS, to evaluate land use impacts in the Delaware River Basin in Pennsylvania. This paper describes application of GIS with the water quality model in the 250 square kilometer Brodhead Creek Watershed. Date used in water quality modeling include 1:250,000 digital elevation models (DEM), soil data, and monitored streamflow and curve numbers, and other input variables.

The purpose of this study is to provide GIS application to the emergency medical service management system in the Seoul area. Two wards, Kangnam-Gu and Songpa-Gu, were selected for a pilot study subject. The main focus of the study was to develope the network system using GIS which could select the most available hospital from the site being emergency case and advise the minimum path to the hospital. ARC/INFO pc version was need to implemeni an indexing system for automated mapping and data storage. The developed system, "Emergency Medical System based on GIS ${\ulcorner}$EMS/GIS${\lrcorner}m$", consists of the cartographic database and vehicle transportation system. The results suggest that EMS/GIS network are needed to connect the local transportation network between major emergency care hospitals and central conirol tower in the near future. If the EMS/GIS system could be more developed based in further analysis, it would be the most useful economical and efficient for emergency medical service with mutual aid system.al aid system.

Many application using GIS has been carried out by governments and public office, and Cungbuk province has produced very effective results on agricultural income crops cultivation suit-land, since executed local autonomy system imported GIS for cope with variation of local administration environment, science of administration. The result on the selection of agricultural cultivation suit-land, in fact, offered us very useful information of the policy establishment concern with agriculture. In this study, we had analysed suit elements of cultivation : soil texture, soil drain, soil slope, soil depth and pH. ARC/INFO and ERDAS systems were used for this study.

Chun-chon city is the area that is estimated to be damaged by breaking of Dam by a flood among several natural disaster. If so, what is the way that minimize the damage\ulcorner There are many ones but it may be best that we take shelter from it before the breaking of Dam. Then when must we do\ulcorner By what instrument can we minimize the damage of people. And how do we compute the time\ulcorner In this study, using buffering, overlap and network, GIS ability based on ARC/INFO. I chose six routesto take shelter outside of Chun-chon city, calculated the traffic volume of each ones, and estimated the time for decentralization of risks.

It is very important to select appropriate methods of collecting, predicting, and analyzing information for the development of urban water resources and the prevention of disasters. Thus, in this study an accurate data generation method is developed using Geographic Information System (GIS) and Remote Sensing (RS). The methods of development and application of an expert system are suggested to solve more efficiently the problems of water resources and quality induced by the rapid urbanization. The time-varying data in a large region, the An-Yang cheon watershed, were reasonably obtained by the application of the GIS using ARC/INFO and RS data. The ESPE (Expert System for Parameter Estimation), an expert system is developed using the CLIPS 6.0. The simulated results showed agreement with the measured data globally. These methods are expected to efficiently simulate the runoff and water quality in the rapidly varying urban area.

Groundwater simulation model suing GIS and Arc/Info Gridfunctions were used to delineate wellhead protection areas. Groundwater simulation model was developed within Arcview GIS. The model. which integrates the data input and manipulation. Process simulation. and display of the results . was developed by considering time variations of the parameters. The model was applied to the EPA data. The hydraulic distributions from the EPA data and those calculated from groundwater simulation model agree well and zone of influence from EPA data and that calculated suing GRID functions seem to be consistent. The developed model may be an efficient tool to delineate WHPA because it integrates all the processes inside the GIS.

Hydrologic parameters vary spatially and require interpretation of maps which often vary in scale and accuracy. Data requirements can be extensive, and acquisition and manipulation of the data are time-consuming. The purpose of this study is to develop Hydrologic Terrain Factor Extract System (HTFES) using Geo-Spatial Information System(GSIS). The HTFES is a package of spatial data and menu-driven programs that allows user-interactive determination of hydrologic parameters. The program employs Arc/Info, a commercial Geo-Spatial Information System. Spatial analysis techniques were employed to define watershed outlets and to determine important hydrologic parameters. The system delineates drainage boundaries, flow paths, average watershed slope and etc. using relevant digital elevation data.

The direction of land use for the subject district (Zuksan-myun, Anseong-gun, Kyeonggi-do) were analyzed as the basic model of new rural land management system connected to production and living. General land use planning was presented by land suitability classification which was applied to geographical information system(software ARC/INFO). The course of analysis of land suitability using the geographical information system were generalized and the results of analysis for paddy and upland fields and settlement were presented as 5 criteria of the suitability rank. It was found out that the analysis of land suitability is able to use as primary data of rural land use planning.

Using remotely sensed data(MOS-1) and other spatial data such as aerial photos and topographic maps, 10 kind of thematic layers were prepared with Arc/Info system for watershed management of Nam Khane River, northern part of Laos. The characteristics of landuse distribution of some criteria which like village, sub-basin, elevation and slope were clarified by overlaying each layer. Therefore, statistic data including shifting cultivation area were produced from database layer. Through the manipulation of some data of each layer, suitable area for permanent paddy cropping converted from the fallow and shifting cultivation area was extracted.
