The Development and Application of Slug Test in Hydrogeology

The slug test is a field-testing method to evaluate hydrogeological parameters by recording the instantaneous change of the underground water level. Basing on abroad development of slug test, this paper tried to measure some parameters of aquifer with middle and high permeability using high accuracy testing. According to field tests and existing pumping data, discussed difference of several theoretic model, analyzed and computed the hydrogeological parameters of a certain spot in Chang Chun, China by classical Cooper Model. At last, comparing with pumping test, the accuracy of the test was verified, which supplied the theory foundation for its application and generalization.
