Sprinkler Irrigation Project Design with Production Functions

Abstract

A linear‐programming (LP) framework with associated design and cost‐estimating procedures is developed to evaluate the economics of deficit irrigation in system design and to optimize the sizing and operation of irrigation system components. The framework includes linear evapotranspiration crop production functions and simulates crop evapotranspiration and crop yields according to irrigation application levels and soil moisture availability. The LP framework considers and accounts for costs for capital, labor, energy, and water, and provides for hydraulic and economic continuity throughout the system. Sprinkler, pipe, pump, canal, and soil systems are simulated, and total system productivity and profitability are determined.
