Abstract: Reducing the contribution of irrigated agriculture to the problem of salt loading in a major river basin is described in both a conceptual and mathematical context. The array of alternative solutions are primarily structural in nature and are oriented towards reducing salt pickup resulting from inefficient irrigation practices. The optimization of salinity control strategies involves combining the best features of several control measures. Consequently, the analyses described are based on finding the minimum cost solution to a salinity control problem involving a specified goal for salt load reduction.
