Abstract: An analysis of closed conduit irrigation systems towards minimal system cost is presented, using a nonlinear mixed integer optimization procedure. Emphasis is on the subdivision of the system into subunits and the relationship between the subunits, design parameters and system cost. The variables defined in the objective function and constraints are the number of manifold and lateral outlets, sizes of mains, submains, supplies, manifolds and laterals. An application example is given.
