Abstract
A review of the current state-of-the-art of prediction modeling as applied to salinity control in irrigation return flows is presented. Prediction models are needed to assess the effects of proposed changes in irrigation management practices on the quality of return flows. The processes which affect salinity levels in return flows are enumerated and their interactions are alluded to. Models used to predict the quantity and quality of return flows are briefly discussed to show the development of the current level of technology. The readers are referred to the original documents for more rigid development of the models and incumbent assumptions. It was concluded that technology of water and salt flow in soil systems is sufficiently developed to permit formulation of models using systems analysis to evaluate proposed changes in management practices. Development of systems models to study irrigation return flow problems and conjunctive water resource uses was recommended. (Author)
