In this study, the economical efficiency of rainwater use is investigated for the water resources of Jeju-Do area. Deciding the supply of rainwater by Graphical Method, and analysing economical benefits by Benefit Cost Analysis, it is concluded that there is an economical efficiency in case of using rainwater. Water consumption of day increases than the cost of rainwater use and tube affection development diminishes. So, retention reservoir is needed for the stable supply of 100m3 water consumption of day. In case of developing joint retention reservoir, the economical efficiency increases. It is needed to develope the rainwater catchment systems by scientific method based on many datum for efficient rainwater use.

This study aims a t the determination of the hydrologic design of storm drainage systems in urban areas by uses storm rainfall and physical basin parameters to predict storm runoff. The design of urban storm drain is determined from the comparison and analysis of several rainfall-runoff models. In this study, the storm-runoff models used ILLUDAS (Illinois Urban Drainage Area Simulator) and Rational models. The basin is divided into sub-basins, one for each design point in the basin. Paved-area and grassed-area hydrographs are produced from each sub-basin by applying the rainfall pattern to the appropriate contributing areas. These hydrographs are combined and routed down-stream from one design point to the next until the outlet is reached.

To identify the characteristics of wastewater flow generated in treatment basins of Seogwipo-city, we selected 3 stations representing the basin and performed 7 times of field survey including 5 times in dry periods and 2 times in wet periods from Feb. 25 to May 27, 2002 for the selected stations. From the analysis of flow data measured for more than 60 days in the interval of 5 minutes and concentration data obtained from laboratory analysis, we can draw several conclusions. First, in the analysis of diurnal variation of wastewater flow for land-use types, we could find the following results: in the residential area, it is observed that wastewater flow rates rise early in the morning for the office-going hour and fall gradually and rise again after the office-leaving hour, showing typical residential wastewater flow pattern, while for the residential and commercial area flow rates rise early in the morning at the office-going hour and move up and down repeatedly within wide range and last till the office-leaving hour, which can be resulted from wastewater that is generated by tourists activated after early in the afternoon, while for the touristy area flow rates rise early in the morning and fall gradually and rise again within wide range. Second, in the analysis of temporal variation of wastewater flow for monthly, it can be observed that in the residential area, in the residential and commercial areas the flow rate of May is higher than that of Feb., March, while for the touristy area flow rate is without monthly because it reflects the movement of population, Third, in wet periods concentration of water-quality item such as SS, BOD, and COD_(cr) is high in the beginning of rainfall by first flush, and falls down gradually to reach the steady state, which is the level of wastewater in dry periods after the cease of storm water due to diluting effect resulting from additional runoff water through storm sewers.

The study is carried out on the runoff analysis for hydrulic and hydrologic characteristic in natural channel by using the Numerical Model which based on the concept of hydraulic flood routing. In analysis, using geomorphology data of land use, vegetation parameter, geological condition, and the condition of channels, and time-spatial distribution characteristic data of storm, runoff analysis is performed. The purpose of this study is to develop optimum runoff in planning and application of a natural channel's water use. The result shows, the analysis of natural channel runoff analysis for hydraulic and hydrologic which is based on the Numerical Model produceds good results when applied to single storm event in basins but the characteristic of peak-discharge toward multiple strom events reduces the results. The model can be used to estimate flood-hydrograph of a unobserved station, because the model does not require obnserved hydrograph to decide parameters.
