SDI Flush Line Design and Precision Flush Management

摘要

A methodology is presented for designing SDI sub-units with Flush Manifolds using UDU (Ultimate Distribution Uniformity) and the CHLR (Cost Head-Loss Ratio). Using CHLR/UDU design protocols solves for the unknowns, qExtra, q Helped, the qNeutral location along the flush manifold, and the qZero array of distal lateral dead flow locations. Solving for these unknowns not only leads to optimal sub-unit design, it forms the basis for operational and flushing solutions in the field. Implementing CHLR/UDU design protocols for sub-unit SDI irrigation design and leveraging finesse to precision manage sub-unit flushing can dramatically reduce system cost, Improve the efficacy of sub-unit flushing compared to traditional solutions, and more correctly assess DUin terms of defined risk.
