RAPID: The effects of typhoon Haiyan's storm surge on coastal aquifers

台风海燕在菲律宾登陆，持续风速为每小时195英里。风暴潮有几米高，来了又去得很快。在一些地方，洪水淹没了内陆1公里。因此，沿海地下水可能受到广泛的海水污染。无数沿海村庄依赖沿海含水层；这些村庄可能不得不与海水污染地下水的长期影响作斗争。PI团队建立了一个150米长的与海岸垂直的样带，以研究与海水通过渗透带渗透及其在含水层中的命运相关的物理和化学动力学。利用电阻率（ER）断层扫描，他们将追踪已经下沉到地下水位以下的咸水，这些海水似乎沿着假定的地下水流向大海。科学目标是提高我们对因风暴潮而被海水淹没后沿海含水层发生的物理和化学过程的理解。本项目得到EAR/HS和ISE/GVF的支持

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
