초록

Groundwater is considered to be the best water resource to solve water shortage problems during drought periods. Eventhough excessive pumping (overdraft) during short-period may give an unprofitable effect on groundwater hydrology, ithas a primary role to solve a lack of water resources and to maintain incomes of farmers. This study evaluated maximumirrigation amounts of groundwater to each local-government and province during drought periods. Maximum irrigationamounts of groundwater were evaluated using cumulative groundwater usage data of each local-government duringnormal and drought years. Maximum irrigation amounts of groundwater during drought periods would be roughlyidentified as approximately 1.3 times more than the exploitable amounts of groundwater resources for each localgovernment.
Drawdown-limitation depth on groundwater levels at each monitoring well was determined by transformingthe maximum irrigating amounts into degree of change on levels. Universal limitation depth of drawdown on groundwaterlevels was evaluated to be approximately three times of annual fluctuating range on groundwater levels for eachmonitoring well. Systematic response on groundwater demands with abiding by drawdown-limitation depth can attain anoptimal irrigation of groundwater resources during short-term drought.
