Systems to control the air–water interface to reduce evaporation from water storages locations
Aims

To explore systems to control the air–water interface to reduce evaporation from water storages.

Key messages
  • Applying a monolayer of ethylene glycol monooctadecyl ether polymer reduced evaporation by 50%–60% under small scale, controlled environmental conditions.
  • Under field situations its efficacy is significantly reduced and produces inconsistent results with evaporation savings of less than 10%.
  • Windy conditions and/or a decrease in the polymer’s longevity on the water surface under field situations probably cause this reduced effectiveness.
