ASCE 12-13, 13-13 AND 14-13

Abstract

The intent of these standard guidelines is to present state-of-theart design guidance for urban subsurface drainage in a logical order. It updates ASCE/EWRI 12-05 <em>Standard Guidelines for the Design of Urban Subsurface Drainage</em> with material developed within the past five years. The collection and conveyance of subsurface drainage waters are within the purview of these standard guidelines for applications such as airports; roads; other transportation systems; and industrial, commercial, residential, and recreational areas. Incidental surface water is considered. <br>These standard guidelines do not address agricultural drainage, landfills, recharge systems, detention ponds, conventional storm sewer design, or the use of injection systems. <br>Customary units and standard international (SI) units are used throughout this document.
