| 摘要 |
PROBLEM TO BE SOLVED: To provide a rainwater storage permeable facility in soil capable of deciding dimensions of such a storage permeable tank which is neither excessive nor overflowed in accordance with the topography and geological features of the land. SOLUTION: A permeable surface gross area x of the storage permeable tank 1 is decided from x = Ks / Q as a formula of the ratio of saturated water permeable coefficient K<SB>s</SB>having surrounding stratum to permeable velocity Q.
