New Tools for Measuring Evaporation from Farm Dams

This bulletin describes the results of a modelling study of evaporation from farm dams and a ‘ready reckoner’ in the form of a spreadsheet that:

• Calculates the cost of installing an evaporation reduction system
• Calculates how much water is saved from evaporating.

The Significance of Night Time Evaporation from Irrigation Farm Dams

Work commissioned by NPSI and undertaken by Matthew Hipsey from the University of Western Australia shows that night time evaporation is significant.

This report details the results of the study and will assist in improving the accuracy….

Scoping Study: Reduction of evaporation from farm dams

Evaporation reduction from farm dams in Australia is regarded as one of the few areas where there are real water savings to be made. At this stage, there are a number of commercial evaporation reduction systems available that use either a hard or polymer cover. Currently these systems are deemed to be viable (M. Durack pers. comm., 2004) for high value crops such as table grapes but are generally not financially viable for lower value crops such as sorghum or cotton.
