Examination of the effectiveness of Multipoint Temperature Logging as the investigation technology of leakage flow of basement of riverbank was performed by a model experiment and field measurement. Results of the model experiment showed that shape of restoration ratio of multipoint temperature can indicates the existence area of permeable layer and the vertical ground flow structure. And the results showed indicated that the faster the groundwater flows the higher the recovering rate of temperature becomes. Results of field measurement showed good agreement with the results of model experiment. Results of Multipoint Temperature Logging in field measurement showed that leakage flows in the riverbank and basement exit in multiple areas. And flowing groundwater often has vertical flow structures.
