지금까지의 지하수 수위분포, 이용현황, 개발가능량, 수질현황 등 지하수조사 성과물은 복잡한 우리나라 지형지세 및 수계형태와 달리 넓은 규모($25{\sim}250km^2$)의 유역(basin) 단위로 작성되어 왔을 뿐만 아니라 수량, 수질관리에 있어서 무엇보다도 중요한 강수량, 지하수위, 이용량, 수질, 오염 등에 대한 명확한 관리기준과 대책을 제시하지 못하고 있다. 따라서 본 연구에서는 GIS를 활용하여 우리나라에 적합한 단위유역(subwatershed) 단위의 강우등급, 수위등급, 이용등급, 오염등급, 수질등급에 대한 분류기준(안)을 제시하고 함평군을 대상으로 시범적으로 적용해봄으로써 그 효율성을 검증하였다.

Drilling at unconsolidated layer can make the aquifer disturbed and reduce a productivity of groundwater well. Surge block and air surging were applied to a pumping well located in Jeungsan-ri, Changnyung-gun, to improve a well efficiency by removing clogging and fine-grained slime. Two experimental log-linear equations, $y_1=-0.1769\;ln(x_1)+0.4960$ and $y_2=-84.3358\;ln(x_2)+512.8162$, were proposed in this site, in which $x_1$ and $x_2$ are the number of surging event, $y_1$ is the amount of slime, and $y_2$ is a recovery time of groundwater level after air surging. Well loss exponent (P) decreased after surging, from 3.422 to 1.439, and the groundwater inflow from aquifer happened in all directions around a well with gradually increasing the homogeneity in a local aquifer's hydraulic property. It was revealed that long-term well development should be done in the pumping well which is located in unconsolidated sediments to increase a well productivity.

산업의 급진적인 발달로 수많은 유해물질이 잔연계로 유출되고 있으며 이들 오염물질은 환경매 체중 최종 수용체인 토양에 유입되어 지하수까지도 위해를 주고 있다. 한편 토양 및 지하수는 유해물질에 의해 일단 오염되면 인위적으로 복원하기 전에는 치유가 되지 않는 특성을 가지고 있어 미국이나 서구유럽의 국가 등 우리보다 산업화가 먼저 이루어진 나라에서는 오염부지 정화 및 관련기술의 개발에 막대한 예산을 투자하고 있다. 그러나 우리나라는 토양오염으로 인한 실태파악이 미비하고 오염부지정화를 위한 관련기술의 개발이 아직 초기단계로 적정관리를 위한 기반이 취약한 설정이다. 따라서 본보에서는 오염부지의 적정 관리를 위해 외국에서 개발·이용되고 있는 정화기술과 오염부지 복구시 관리절차에 대해 살펴보았다.

근래에 우리나라에서도 지하수부존량과 개발가능량의 산정방법에 관한 여러 연구가 수행되고있으나 대개 전국적이거나 광역적인 개념으로 검토되어 왔다. 지하수 이용계획 수립 또는 지하수 환경 영향평가의 관점에서는 소 구역의 지역단위 개념으로 지하수 개발가능량을 분석하여야 하므로 지역단위 지하수함양량 산정방법의 연구가 요구되고 있다. 지역단위 지하수함양량 산정에 대하여 실무적으로 쉽게 적용할수 있는 두가지 방법을 연구하여 제안하였다. 그 하나는 SCS-CN방법에 의하여 강우의 침투량을 구하고 여러해의 평균 침투량과 평균 강우량을 비교하여 지하수 함양율을 구하는 것이고 다른 하나는 자연상태의 지하수위 변동량을 관측 분석하여 지하수 함양율을 계산하는 것이다.

Groundwater level hydrographs from observation wells in Jeju island clearly illustrate distinctive features of recharge showing the time-delaying and dispersive process, mainly affected by the thickness and hydrogeologic properties of the unsaturated zone. Most groundwater flow models have limitations on delineating temporal variation of recharge, although it is a major component of the groundwater flow system. Recently, a convolution model was suggested as a mathematical technique to generate time series of recharge that incorporated the time-delaying and dispersive process. A groundwater flow model was developed to simulate transient groundwater level fluctuations in Pyoseon area of Jeju island. The model used the convolution technique to simulate temporal variations of groundwater levels. By making a series of trial-and-error adjustments, transient model calibration was conducted for various input parameters of both the groundwater flow model and the convolution model. The calibrated model could simulate water level fluctuations closely coinciding with measurements from 8 observation wells in the model area. Consequently, it is expected that, in transient groundwater flow models, the convolution technique can be effectively used to generate a time series of recharge.

Rural groundwater monitoring network has been managed by Korea Rural Community Corporation (KRC) since 1998. The network consists of two kinds of subnetworks; rural groundwater management network (RGMN) and seawater intrusion monitoring network (SIMN). RGMN has been operated to promote a sound and sustainable development of rural groundwater within the concerned area for groundwater quality and quantity. SIMN has been operated to protect the crops against hazards by the saline water in coastal areas in which the shortage of irrigation water become a main problem for agriculture. Currently, a total of 283 monitoring wells has been installed; 147 wells in 79 municipalities for RGMN and 136 wells in 52 ones for SIMN, respectively. Two subnetworks commonly monitor three hydrophysical properties (groundwater level, temperature, and electric conductivity) every hour. Monitored data are automatically transferred to the management center located in KRC. Data are opened to the public throughout website named to be the Rural Groundwater Net (www.groundwater.or.kr). Annual reports involving well logging and hydrochemical data of RGMN and SIMN have been published and distributed to the rural water management office of each municipalities. In addition, anyone who concerns about RGMN an SIMN can freely download these reports throughout the Rural Groundwater Net as well.

The natural hydrology and geological conditions of Xintian County was investigated, the development law of regional karst fissures was studied, the groundwater was collected and tested through a large-scale collection of groundwater to obtain the change law of chemical characteristics and water quality characteristics of groundwater, and the water quality evaluation was carried out for the regional karst groundwater in this paper. The results show that, the whole area is dominated by carbonate rock distribution areas, and the distribution of water systems is relatively developed. The strata are distributed from the Lower Paleozoic Cambrian to the Cenozoic Quaternary, and contain multiple first-order folds. The regional karst dynamic action is strong, and many tunnels or caves of different scales were shown, which are conducive to the enrichment of groundwater. Karst groundwater is neutral and alkaline water, the water is clear and transparent with good taste, and meets the national drinking water hygiene standards. The content of toxic trace elements and fluoride in the water source is generally lower than the limit value specified by the national standard and the accumulated toxic heavy metals is never found. The overall water quality is of good quality and suitable for the development and utilization of various purposes.

어떤 특정 지역의 지하수 개발량을 적적히 파악하기 위해서는 지하수함양량의 산정이 필요하다. 경상북도에 위치한 위천 유역내의 소유역에 대하여 지하수 함양량을 산정하였다. 기저유출분리법과 SCS-CN방법을 이용하여 갈수년과 풍수년이 존재하는 1992년∼1997년간의 년 평균 지하수 함양량을 추정하였다. 기저유출분리법을 이용하여 추정한 결과, 연평균 지하수 함양률이 11.9%∼18.7%로 변화하였으며 계산기간 중의 년 평균 강수에 의한 지하수 함양량은 141.6mm로 지하수함양률은 14.5%이었다. SCS-CN방법을 이용하여 추정한 결과, 연평균 지하수 함양균이 7.9%∼20.9%로 변화하였으며 계산기간 중의 년 평균 강수에 의한 피하수 함양량은 147.4mm 로 지하수 함양률은 15.1%이었다. 두 방법으로 산정한 갈수년과 풍수년이 존재하는 장기간 동안의 년 평균 강수에 의한 지하수 함양량은 지하수 개발에 유용하게 사용할 수 있음을 나타낸다.

Protected horticultural complexes would increase crop productivity but would adversely affect the groundwater recharge function in the area because the impervious area would increase. Further, they would limit the movement of living beings, affecting biodiversity. Therefore, this study evaluated the groundwater ecosystem services provided by protected horticultural complexes in terms of consistent utilization of water. The estimated amounts of groundwater loss obtained through quantitative assessment of groundwater infiltration showed that a higher impervious area results in higher losses. We, therefore, predict a much higher loss if similar changes in land use are realized on a nationwide scale. A plan to promote groundwater recharge in impervious areas is actively being discussed for urban areas; however, this plan is not yet applicable to farming areas. We consider it is essential to develop groundwater infiltration facilities for horticultural complexes, infiltration trenches, permeable pavements, surface water storage facilities, water purification facilities, etc. Further research and development of groundwater infiltration facilities is important for consistent utilization of water and the improvement of ecosystem services.
