Abstract

The convolution equation for the flood wave response model was used to estimate aquifer diffusivities using the groundwater levels in a selected well in the Mangyeong River floodplain. of no precipitation were used as inputs to the flood wave, which had a high correlation with river levels near the river, and uncertain leakage to the river channel and possible recharge from precipitation can be neglected. Pumping tests can determine local aquifer properties, but the flood wave response technique is a good tool in a sense that the overall aquifer diffusivity related with hydraulic interaction of a river-aquifer system can be estimated. The flood wave resurvey methodology proposed in this study can be effective if the peaks of the flood wave response are well defined and the observed groundwater heads are strongly correlated with river water level fluctuations.
