Are Groundwater Inputs into River-Dominated Margins Important?

该项目的重点是以大河为主的东南亚沿海地区河流和海底地下水排放之间的平衡。 利用地球化学示踪剂（氡和镭同位素），研究人员将研究两个以河流为主的系统中的地下水和河流产生的通量，他们在这两个系统中建立了强有力的国际伙伴关系：（a）黄河-渤海和（B）湄南河-泰国湾。 由国际合作者进行的平行生物地球化学研究将使人们能够直接比较河流和地下水输入的与沿海地区生物有关的化学物种。 该项目将有助于发展中国家和美国的人力资源开发，并将对人口稠密地区的沿海地区水资源管理产生重要影响。

This project focuses on the balance between riverine and submarine groundwater discharge in Southeast Asian coastal zone areas dominated by large rivers. Using geochemical tracers (radon and radium isotopes), the researchers will study both groundwater and river-derived fluxes in two river-dominated systems in which they have established strong international partnerships: (a) The Yellow River-Bohai Sea and (b) the Chao Phraya-Gulf of Thailand. Parallel biogeochemical studies to be performed by international collaborators will permit direct comparisons of the river- and groundwater-derived inputs of biologically relevant chemical species to the coastal zone. The project will contribute to human resource development in developing countries and the U.S. and will have important implications for coastal zone water resource management in highly populated areas.
