Abstract

Yellow River is one of the largest rivers in the world and provides many sands to the sea. There is the large delta of Yellow River in the lower reach, and it is continuing to grow up by sediment from the river. However, some environmental issues occur such as the problem which river water can not reach to the river mouth from depletion of river water by overuse since 1970's. In this region which has experienced some environmental issues, groundwater research include the resistivity survey were conducted for the evaluation of the distribution of freshwater and saltwater under the delta in September 2003, May 2004 and September 2004. According to the results of field research, it is assumed that there is fresh groundwater in the shallow part and south of this delta, and saltwater widely in other region. We also applied the age dating of groundwater using carbon fourteen method. As a result, there are young saltwater near the shore and paleo-seawater in the center of this delta.
