Porewater Pressure Predictions on Hillside Slopes for Assessing Landslide Risks(III)-Model Parameter Identification-

산사태 위험도 추정을 위한 간극수압 예측에 관한 연구 (III)-모델 매개변수 분석-

In general, the conceptual lumped-parameter groundwater flow model to predict the groundwater fluctuations in hillside slopes has unknown model parameters to be estimated from the known input -output data. The purpose of this study is to estimate the optimal model parameters of the groundwater flow model developed by authors. The Mazilnum A Posteriori( MAP) estimation method is utilized for this purpose and it is applied to a site which shows the typical landslide in Korea. The result of application shows tllat the 반AP estimation method can estimate the unknown parameters properly well. The groundwater model developed along with estimation technique applied in this paper will be used for assessing risk of landslides.
