Optimization of a sequential irrigation system on differential irrigation plots

Summary

The optimization of a sequential irrigation system used on differential irrigation areas is considered. The sequential regime of differential plot irrigation is analyzed in detail. Target functionals have been generated for the synthesis of two extreme modes of sequential irrigation of differential plots based on the Kostiakov–Lewis equation and its derivation. As a result of the analysis using the variational optimization method, it was found that the first synthesized extreme mode provided for minimizing the corresponding target functional with an inverse relationship between the irrigation time and plot area, which is estimated as a negative extreme mode; the second synthesized extreme mode, with a limited total irrigation time, allows for a direct dependence of the irrigation time on the irrigated area, ensuring the maximum of the assumed optimization criterion.
