Abstract (in Japanese) (See Japanese page) 
(in English) This paper describes new water sensor modules for detecting underground closures that water has penetrated. We evaluated the prototype bending module and marker module, and confirmed the application of detection. A bending module that controlled bending loss can detect two or more underground closures that water has penetrated. A marker module easily identifies underground closure that water has penetrated.
