The distribution characteristics and migration mechanism of seepage field of reservoir groundwater can determine the geographical characteristics of reservoir area to a large extent. The permeability of reservoir area is especially important since it is an important indicator of karst development characteristics and its hydrogeological condition in karst area, and it’s difficult to conduct quantitative analysis of its parameters. According to the needs of practical engineering application, I use the C# and FORTRAN program to design a calculation method. I also use seepage field numerical simulation in reservoir area of one pumped storage power station on the east to testify the correctness and practicability of this calculation method. Judging from the groundwater level contour map, we can see that groundwater shed and surface water shed are basically the same. Groundwater can be distributed to surrounding areas from the upper reservoir. Because of the resistance effect of non-karst area on north and south, groundwater flows out in the form of spring in north and south. The groundwater flows to Zimei Bridge on east side, and Yaoshiwan on west side. The repeated experiments of parameters show that groundwater seepage field is insensitive to the change of other areas’ permeability parameter. Results show that this calculation method is well-adapted, accurate, applicable and practical.
