Abstract: Given the complexity and difficulty of tracing and detecting the Karst seepage field,the problems such as imperfect information and discrepancies often arise to calculate the underground capacity of karst reservoir using hydrogeological,hydraulic,and hydrological parameters. The capacity calculation based on tracing and detecting method is not dependent on those parameters. The study and calculation on the underground capacity of Lujiaoba depression reservoir indicate that under certain conditions,tracer agent is ergodic to seepage field due to its diffusion rule and is measurable of water filling space in the seepage flow field due to the conservation of mass. For these reasons,information about flow field obtained through tracing and detecting is more completed, and the underground capacity of Karst reservoir calculation is more accurate.
