Uncertainty Approach to Subirrigation Design

Pages 79-85 | Published online: 23 Jan 2013
 

Abstract

The first and second order method of analyzing uncertainty is incorporated into the design of subirrigation systems. The uncertainty in the design due to both the unsaturated and saturated hydraulic conductivity is considered. Numerical examples are given that show how the method may enable designers of subirrigation systems to estimate confidence limits on the design drain spacing.

La méthode d’analyse d’incertitudes, de premier et de second ordre, est incorporée à la conception de réseaux d’irrigation souterraine. On tient compte de l’incertitude touchant la conception, due à la conductivité hydraulique saturée et non saturée Des exemples numériques indiquent comment la méthode peut permettre aux responsables de conception de réseaux d’irrigation souterraine d’évaluer les limites de confiance pour l’écartement nominal des drains.
