Recently, the development of industry and improvement of standard living is increasing the water demand. For preventing expected water shortage, it is important to plant an effective way in utilization of water resources from now. We concerned the water shortage in the future at Shimabara district and central Nagasaki Prefecture. In this area there are few suitable places for dam sites. Rainwater faIled on the ground are easily permeated into underground because of well permeability geological futures. The ground water then flushed out to the coast or to the sea as submarine springs. It seems that it is more effective to collect these submarine springs than to develop dam sites for water resources. This paper discussed the results of survey carried out in situ in Simabara Peninsula, Taradake/Ariake Bay and Omura Bay, in which the ground water has tendency to flow out to the coast or to the sea by comparing them with those of analyzing remote sensing data.
