Development of Procedures to Evaluate Salinity Management Strategies in Irrigation Return Flows

摘要

The purpose of this research was to assess the state-of-the-art of hydrosalinity modeling in order to develop a practical management tool for predicting how the salt outflow from irrigated agriculture is affected by various farm management practices. This review identified one of the major gaps in modeling as inadequate understanding and representation of the quantity and quality interrelationships between surface water, drainage water, and groundwater. The study also identified that a site specific equilibrium 'threshold concentration' (TC) of dissolved solids can be adequately estimated and represented in a model.
