How Much Water Are You Losing To Evaporation

How Much Water Is Your Dam Losing To Evaporation?

Evaporation loss from farm dams in Australia is a great challenge to water security, ranging from 9% to 36% loss of total volume of water in summer. Reliable quantification and prediction of losses are complicated by numerous factors that include meteorology, dam shape, and inaccuracies in measurement. This paper explores the complexities of evaporation estimation, the limitations of current practice, and the potential for improvement through advanced modeling and abatement technologies like floating covers and windbreaks. Understanding these dynamics is essential to effectively manage water in Australia’s agricultural regions.

When The Heat Hits: Why Australia’s Dams Are Under Pressure

Short answer: Extreme heat events accelerate water loss from Australian dams through evaporation, while simultaneously increasing demand from livestock and irrigation, placing enormous pressure on storage reserves. Climate trends toward hotter and drier conditions mean this pressure is becoming a more regular challenge for rural water managers. Building larger, deeper, and better-sealed dams is the …
