地すべり地における地下水調査法について ―新しい地下水調査法の必要性と試み―

Abstract

It was cleared by the existing investigated results that the underground water was existent asthe vein-stream condition in and around the landslide area. By the results, the author was awarethat it was very difficult to obtain the information which was concerned with the existent locationof the underground water vein-stream using the present tracer method.
