Experimental Study of Artificial Groundwater Recharge by Basin Method

Noboru Hida

Abstract

An experimental study of groundwater recharge by means of recharge basin has been done in a dune area of Showamachi, Akita Prefecture. Raw water source was withdrawn from the Hachirogata regulating reservoir. The purpose of this study is to make certain of storage of recharge water and changes in water quality. The experimental equipments consist mainly of a recharge basin (area of 10× 20 m and 0.4 m deep), a pumping well (14 m deep) and six observation wells (each 8 m deep). Water was analyzed in laboratory. The structural phases of the equipments are explained in this paper. Results obtained are discussed in the following papers.
