Abstract: Optimal command areas and level border irrigation design parameters are obtained for a given available seasonal water supply using a dynamic programming (DP) optimization approach. The DP algorithm optimizes net benefits for a given project area while incorporating hydraulic characteristics of the application system and on-farm constraints. A performance parameter function describing border irrigation requirement efficiency is utilized for determining production costs and net benefits for various assumed water supply levels. Optimal areas of irrigation, cropping patterns, water allocation and time of application are calculated.
