Abstract
Porous concreate (POC) pavement has been spreading as one of flood control procedures in an urban area. Though the permeability test for POC is based on linear Darcy's law: q=Ki, it is high possible that POC's permeability law has non-linearity because of its large pores. In this study, through accurate permeability experiments with various glass beads from fine to coarse, relationships between non-linear law: q=K'im and particle size dm of media was investigated. In addition, theoretical expressions of seepage flux were formulated by hydraulic consideration on laminar and turbulent flow in pore space of media.
