Typhoon Haiyan made landfall in the Philippines with sustained winds of 195 mph. The storm surge was several meters high and came and dissipated quickly. The inundation reached 1 km inland in some places. Thus, there is potential for extensive seawater contamination of coastal groundwater. Countless rural coastal villages are dependent on coastal aquifers; these villages might have to contend with the long-lasting effects of seawater contamination of groundwater. The PI team established a 150 m long shore-perpendicular transect to investigate the physical and chemical dynamics associated with infiltration of the seawater through the vadose zone and its fate in the aquifer. Using electrical resistivity (ER) tomography, they will track the saline seawater that has now sunk a little bit below the water table and appears to be following postulated groundwater flow paths towards the sea. The scientific objective is to improve our understanding of the physical and chemical processes occurring in coastal aquifers after inundation by seawater due to storm surges.This project is supported by EAR/HS and ISE/GVF

台风海燕以每小时195英里的持续风速在菲律宾登陆。 风暴潮高达数米，来的快，去的也快。洪水在一些地方深入内陆1公里。因此，沿海地下水有可能受到广泛的海水污染。 无数沿海农村村庄依赖沿海含水层;这些村庄可能不得不应对海水污染地下水的长期影响。 PI小组建立了一个150米长的海岸垂直断面，以调查与海水通过渗流带渗透及其在含水层中的命运有关的物理和化学动力学。使用电阻率（ER）层析成像，他们将跟踪现在已经下沉到地下水位以下一点的盐水，并且似乎正在沿着假定的地下水流路径流向大海。 科学目的是提高我们对沿海含水层在风暴潮海水淹没后发生的物理和化学过程的认识。该项目得到了澳大利亚水文局/HS和伊势/GVF的支持
