Step-drawdown pumping tests for identifying the improvement of groundwater well performance after rehabilitation treatments were conducted in three longstanding wells. Three selective mechanical treatment methods including power bubble, high-voltage electric pulse, and air surging were applied to these wells and the applicability of these methods to secure additional groundwater resources were evaluated quantitatively. Commonly, drawdown at final stage of stepdrawdown pumping tests after rehabilitation decreased by as much as 0.61~0.70 meters compared to those before rehabilitation. In addition, final specific drawdown values of three wells increased from 9% to 14% after rehabilitation. Formation loss coefficient and well loss coefficient decreased to 6.1% and 60.6%, respectively, indicating some clogging materials by precipitation/corrosion/microbe within pores of aquifer materials, gravel packs, and screens were effectively removed by applied methods. Decrease of formation loss coefficient was higher in the well applied by the power bubble method meanwhile high-voltage electric pulse method demonstrated the higher decrease of well loss coefficient. Additionally secured groundwater amounts after rehabilitation ranged from 23.3 to 32.1 m³/day, which account for 8~16% of initially developed pumping rates of the wells. From the results of this study, the effective selection of rehabilitation treatments considering aquifer characteristics are expected to contribute to secure groundwater resources for irrigation as well as to plan systematic management program for groundwater resources in rural area.

A set of geophysical survey results over an area in Bookil-myun, Chungwon-Gun, Chengcheong-buk-Do is presented; resistivity logging, d.c. sounding, dipole-dipole resistivity, and controlled-sorce magnetotelluric (CSMT) surveys. These surveys were chosem in this research for the estimation of the basement depth and the delineation of the hydrogeologic srtucture over the survey area. The results provide an optiomal input to a hydrogeologic medeling analysis usinf the strategies built in GIS softwater. A total of 14 lines of dipole-dipole resistivity surveys, 25 stations of D.C sounding and 6 stations of CSMT sounding were performed. In addition 10 boreholes were chosen for resistiveity logging to correlate the logs to the surface data. A quantitative information on the hydrogeologic structure over the are is provided by synthesizing the results from various geophysical data and attribute layers are constructed by utilizing a GIS software Arc/Info. The constructed layers match well to the hydrogeologic structures, which were outlined from the drilling data. The methodology tested and adopted in this study would be useful for providing a more reliable input to the hydrogeologic model setup.

In general, carbon-based materials play a major role in today’s science and technology and are required to advance with better properties to meet new requirements or to replace existing materials. We fabricated rubber composites reinforced with 5-weight% acid-graphite. The structural, mechanical and thermal properties of these composites were studied and compared. XRD studies indicated that the structure of the acid treated pristine-graphite (acid-graphite)did not change that of pristine graphite. Tensile properties of the composites indicated higher modulus, tensile strength and elongation in comparison with composites of pristine graphite, carbon black. Also, the composites were found to be in improving tendency with thermal properties and fatigue properties. The acid-graphite was investigated for surface morphology by scanning electron microscopy (SEM) and defects or purity by Raman spectroscopy. In this article, we discuss the influence of acid-graphite on rubber with high mechanical and thermal properties.

In this study, the projected land use area in 2030 for major crop production was estimated in Jeju Island using land cover map, and corresponding agricultural water demand for 40 sub-regions was quantitatively assessed using the future climate change scenario (RCP 4.5). Estimated basic unit of water demand in 2030 was the highest in the western region, and the lowest in the eastern region. Monthly maximum agricultural water demand analysis revealed that water demand in August of 2030 substantially increased, suggesting the climate of Jeju Island is changing to a subtropical climate in 2030. Agricultural water demand for sub-region in 2030 was calculated by multiplying the target area of the water supply excluding the area not in use in winter season by the basic unit of water demand, and the maximum and minimum values were estimated to be 306,626 m3/day at Seogwipo downtown region and 77,967 m3/day at Hallim region, respectively. Consequently, total agricultural water demand in Jeju Island in 2030 was estimated to be 1,848,010 m3/day.

방조제 제체 보강에 따른 기수호 수질 및 제체 수리지질 특성 변화

To evaluate the effectiveness of reinforcement for prevention of seawater inflow through embankment, we carried out the spatial analysis with kriging method for measured electrical conductivities (EC) at eight points located within the brackish water reservoir and analyzed cross-correlation of water level variations with tide at four monitoring wells at the embankment before and after the reinforcement. From the EC variation during two years before and after reinforcement, it was inferred that seawater inflow regions were through the lower region of embankment where the high EC regions were identified before reinforcement while the high EC regions were moved to the inner brackish water reservoir after reinforcement. From correlation analysis results of water level variations at selected monitoring wells with tide, it was demonstrated that integrity of the embankment was improved because both time lags and maximum cross-correlation coefficient values were markedly increased and decreased, respectively. From this study, these two methods are revealed to be effective to evaluate reinforcement for embankment. 방조제 제체를 통한 해수유입의 차단 효과를 평가하기 위하여, 기수호 내 8개 지점에서 보강공사 전후 약 2년간 정기적으로 심도별 전기전도도 및 온도 변화를 측정하였다. 또한 제체에 설치된 4곳의 수위관측공에서 측정된 수위변화 자료를 조위변화와 교차상관분석을 실시하였다. 약 2년간의 전기전도도 분포를 분석한 결과 보강공사 이전에 북서쪽에 형성된 높은 전기전도도 분포 범위가 보강공사 이후 서쪽으로 변화했으며, 전체적으로 전기전도도값이 낮아지는 것으로 나타났다. 제체에 설치된 수위관측공의 수위변화 자료를 조위와 교차상관 분석한 결과 시간지연과 교차상관계수가 각각 현저하게 증가 및 감소함에 따라 제체 보강공사에 의한 해수유입 현상이 차단되는 것으로 나타났다. 결과적으로 정기적인 기수호내의 전기전도도 공간분석과 조위변화에 따른 제제내의 수위변화의 교차상관분석 기법은 방조제 제체의 보강효과를 평가하는데 유용한 것으로 밝혀졌다.
