Abstract

<p> The purpose of this study was to develop a simple 3-D groundwater flowmeter to directly measure seawater inflow to the beach, and to clarify the occurrence of vertical seepage during the rising tide and seawater upwelling during the falling tide. A new paper-cylinder type groundwater flow directional anemometer was devised, tested in a laboratory experiment, and used to observe coastal groundwater infiltration in Yamaguchi Bay. As a result, it was possible to measure the three-dimensional groundwater flow directional velocity of groundwater infiltrating into the beach in 15 minutes, and the groundwater recharge and discharge of the beach at the site were clarified.</p>
