Abstract

A series of three-dimensional numerical simulations using a generalized multidimensional hydrodynamic dispersion numerical model is performed to simulate effectively and to evaluate quantitatively impacts of urbanization on density-dependent groundwater flow and salt transport in a coastal aquifer system, Suyeong-Gu, Busan, Korea. A series of steady-state numerical simulations of groundwater flow and salt transport before urbanization with material properties of geologic formations, which are established by numerical modeling calibrations considering all the urbanization factors, is performed first without considering all the urbanization factors. A series of transient-state numerical simulations of groundwater flow and salt transport after urbanization is then performed considering the urbanization factors individually and all together. Finally, the results of both numerical simulations are compared with each other and analyzed. The results of the numerical simulations show that density-dependent groundwater flow, salt transport, and seawater intrusion in the coastal aquifer system are intensively and extensively impacted by the urbanization factors. Especially, these urbanization factors result in the changes of the total groundwater volume and salt mass in the coastal aquifer system. However, such impacts of each urbanization factor are not spatially uniform but locally different.

한국 부산광역시 수영구 지역 해안 대수층 내의 밀도 의존적 지하수 유동 및 염분 이동에 대한 도시화의 영향을 효과적으로 모사하고 정량적으로 평가하기 위하여 하나의 범용 다차원 수리동역학적 분산 수치 모델을 이용한 일련의 삼차원 수치 모델링이 수행되었다. 먼저 모든 도시화 요소들을 고려한 수치 모델링 보정을 통해 확립된 연구 지역해안 대수층의 지층 물성을 가지고, 도시화 요소들을 모두 고려하지 않은 도시화 이전의 지하수 유동과 염분 이동에 대한 정상 상태 수치 모델링을 수행하였다. 그 다음에 도시화 요소들을 개별적으로 그리고 통합적으로 고려한 도시화 이후의 지하수 유동 및 염분 이동에 대한 비정상 상태 수치 모델링을 수행하였다. 그리고 두 수치 모델링 결과를 서로 비교하고 분석하였다. 수치 모델링 결과는 해안 대수층 내의 밀도 의존적 지하수 유동 및 염분 이동 그리고 해수 침투가 이러한 도시화 요소들에 의해 크게 그리고 광범위하게 영향을 받음을 보여준다. 특히 이러한 도시화 요소들은 해안 대수층 내의 총지하수량 및 총염분량의 변화를 초래한다. 그러나 각 도시화 요소의 그러한 영향은 공간적으로 균일하지 않고 국부적으로 차별적이다.
