| Summary: | 碩士 === 國立中興大學 === 土木工程學系 === 90 === In September 21 ,1999 , chi-chi earthquake happened in Taiwan . It made Chiufengershan sliding . The colluviam deposit generated a new groundwater system because of the generous falled soil and rocks jamed the confluence of Chiutsaihuhsi and Satsikenghsi.
In this research , VLF（very-low-frequence）method and ground magnetism method were used to prospect ground condition for colluvium deposit . The results of prospect tells that the groundwater veins are relation to origional riverbed .
Second , PMWIN ( Processing Modflow for Windows ) were used to develop a regional groundwater conceptual model to study the groundwater seepage condition . After the model are verified by field slug-test , then it is applied to test run for design of discharge system including pumping wells and horizontal drainaged pipes . The effectiveness of reducing groundwater-level can be refer to engineering plan .
