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

This report documents the numerical analysis performed for the Land and Water Australia (LWA) National Program for Sustainable Irrigation project.

For this analysis the 1 D hydrodynamic model DYRESM was used to simulate 10 idealised dams ranging in geographic (and climatic) location and morphometry DYRESM was used to simulate the water balance and thermal struct

Right now, it is very difficult to accurately measure the water losses from evaporation on farm dams but a recent scoping study funded by the National Program for Sustainable Irrigation estimated the loss is as high a
