Considerations for the design and installation of SDI systems in humid areas. In: Proceedings of the World Water and Environmental Resources Congress. American Society of Civil Engineers, Reston, VA. Available: http://ascelibrary.aip.org/getpdf/servlet/GetPDFServlet?filetype=pdf&id=ASCECP000173040792000518000001&idtype=cvipsInterpretive Summary:
                                Technical Abstract: Humid areas, such as the southeastern and midsouthern United States, have particular climate, topography, soils, cropping systems, and water sources that require special consideration when considering and implementing a subsurface drip irrigation (SDI) system.  Design criteria, are generally the same in humid areas as in arid or semi-arid areas, but these factors are normally different enough in value or type to result in a different system design.  Irregularly shaped fields commonly found in humid areas can result in a system layout that differs greatly from a typical layout.  Installation is best done when the soil moisture is within an optimal range, which may seriously limit installation windows in humid areas.  As fewer systems have been installed in humid regions, availability of professional installers and installation equipment can be problematic.  This paper presents both design and installation considerations for SDI systems, with particular emphasis placed on conditions found in humid areas.  It is condensed from two publications in a series designed to provide guidance on SDI systems in humid regions in an 'extension-like' format. Topics include: water supplies; pumps; filtration; chemical injection; main, submain, lateral, and flush line design; instrumentation and control systems; design implementation; installation tips; and locating an installer.
