Generally speaking,the optimal design of irrigation pipe networks contains two respects:diameter optimization and pipe networks layout optimization. A satisfied result has been attained in the former study. However, no refercnces about the latter study has been found.This paper,based on the optimal desegn of irrigation pipe networks system, introduced the optimal layout for irrgation pipe-networks by orthogonal table method. The given example showed this method was effective and reliable.
