Purpose& contents
This study aims to improve applicability of various rainfall generators to Korea and apply these data to numerical simulation which can influence the hydrological process and analysis. This will suggest a new approach to hydrological process.

So in this study, various rainfall generator models will be investigated and improved for the rainfall events in Korea. Then selected model will be applied to hydrological modelling on the main watersheds in Korea to improve the applicability. After all, this study will suggest stochastic approach to determination of national policy of construction and environment.

Result
Through the validation process to find the most applicable rainfall generator model, Poisson rainfall generator model is selected.

As Poisson model is selected for the main research theme, The Hybrid Model(THM) which can consider inter-annual variability of rainfall is validated for United States. In case of Korea, Modified Bartlett-Lewis Rectangular Pulse(MBLRP) rainfall model and XP-SWMM are used for the applicability of flood simulation. After validation, parameters of MBLRP model are regionalized and monthly parameter maps are made.

Lastly, rainfall generator model which can consider climate change is developed. Bayesian sampling method considering combination of 16 GCM resluts is developed and by using this, future rainfalls can be generated in a unit of month.

Expected Contribution
By validation and application of the rainfall generator model which is necessary for the analysis of hydrological process, future scenario of water quality, flood, drought, environment can be drawn in Korea main watersheds.

Especially suggested model in this research can provide not average rainfall but rainfall of specific year in the future. So as the climate change, rainfall data for making a plan of irrigation and hourly rainfall data which have long future time series will be used for the analysis of urban flood and hydrological simulation.
