Application of automated flow and salinity control to dilution of saline irrigation water

Summary

The utility of a saline water source for irrigation might, in many cases, be greatly increased if it could be diluted by mixing it with a higher quality source of water prior to field application. This paper discusses a number of options for achieving such a dilution subject to imposed constraints. Firstly, we derive and discuss the principles of achieving control of irrigation salinity level when waters of two different qualities and flow rates are used. Secondly, we formulate and discuss the dynamic performance of a prototype on a controlled dilution junction with and without water storage. Finally, we discuss the general problem of achieving simultaneous salinity and flow rate control, using dual feedback control sensors to compensate for variations both in salinity and in flow rate of the saline supply source in order to produce a desired salt concentration in the irrigation water.
