Abstract: Electrical resistivity tomography (ERT) has been widely applied in hydrology during recent years with its high efficiency and precision. Based on summary and analysis the huge number of bibliographies,considering the complicated factors that affect the electrical resistivity underground,the relationship between the resisitivity and hydraulic parameters,such as water content,hydraulic conductivity,porosity,solution and so on,have been listed in this thesis,emphasizing on the application of ERT on...
