Abstract

We evaluated the results of pumping tests, the amount of groundwater used by Protected Cultivation with Water Curtain (PCWC), and monthly depth to water table (DTW) at the Wangjeon-ri area, Nonsan City, to elucidate the cause of a decrease in pumping rate during the winter PCWC season. The transmissivity and storage coefficient at eight sites where the major aquifer is alluvium, vary from 119.9 to $388.1m^2/d$ and $1.5{\times}10^{-4}$ to $5.5{\times}10^{-4}$, respectively. The pumping rate for PCWC during three months (Dec. to Feb.) averaged about $8,100m^3/d$ and the maximum water level in the area varied by about 10 m. Groundwater levels had fully recovered by August-five months after pumping for PCWC had ceased. These observations indicate that the pumping rate during the winter PCWC season was excessive compared with groundwater productivity in the area. Groundwater level in the central PCWC area varied from -3.0 to 4.38 m, exceeding the water level of the Nosung Stream for only three months (Aug. to Oct.). This result indicates that Nosung Stream recharges the area during the period from November to July. To solve the problem of reduced pumping rate during the winter PCWC season, it would be necessary to reduce the amount of groundwater used for PCWC or to develop an artificial recharge system using recycled groundwater.

겨울철 수막재배를 하고 있는 논산시 왕전리지역의 지하수 취수량감소 원인을 파악하기 위하여 양수시험을 실시하였고, 수막재배에 이용되고 있는 지하수 사용량과 월별 지하수위를 측정하였다. 8개 지하수공에서 양수시험 결과 투수량계수는 $119.9{\sim}388.1m^2/d$, 저류계수는 $1.5{\times}10^{-4}{\sim}5.5{\times}10^{-4}$의 범위이고 주 대수층은 충적층으로 나타났다. 수막재배용 지하수의 양수는 겨울철 약 3개월에 걸쳐서 일어나며 일평균 양수량은 $8,100m^3/d$ 정도였으며 연간 최대 지하수위 변동은 10 m까지 일어나고 있다. 연구지역의 지하수위는 수막재배용 양수가 중단된 지 5개월이 지난 8월에야 완전한 수위회복을 보인다. 이는 연구지역 대수층의 지하수 산출능력에 비해서 겨울철 수막재배시기의 과도한 양수에 의한 것으로 해석된다. 연구지역 중심부 일대의 지하수위는 -3.0~4.38 m로서 연간 8, 9, 10월을 제외한 나머지 9개월은 노성천 하천수위보다 낮아서 하천수가 연구지역으로 유입되는 손실하천의 양상을 띤다. 연구지역에서 겨울철 수막재배에 따른 취수량 감소문제를 해결하기 위해서는 지금보다 규모가 적은 수막재배시설을 운영하여 양수량을 줄이거나 수막재배에 이용된 지하수를 재활용하는 인공함양 수막재배시스템 개발 등이 필요하다.
