| It is necessary to estimate the groundwater recharge rate properly to evaluate the reasonable development amount of groundwater in a specific site. A small basin in Wicheon River Basin located in the Province of Kyungsangbuk-Do is selected to calculate the groundwater recharge rate. Average annual groundwater recharge rates are calculated from 1992 to 1997 because wet and draught year are contained during this period. In the calculation, baseflow separation method and SCS-CN method are applied to this area. As a result of estimation by baseflow separation method, the value of groundwater recharge ratio is varied between 11.9% and 18.7%. The average annual recharge rate is 14.5%. The average annual recharge rate calculated by SCS-CN method is varied between 7.9% and 20.9%. The average annual recharge rate in the calculation period is 15.1%. The results show that the average annual recharge amount from infiltration in the study basin is 141.6mm and 147.4mm in each estimation method. It appears that the average annual recharge amount calculated for the long period containing wet and draught year by the two methods is useful for groundwater development. |
