Woodlands transpire large amounts (> 80 % of rainfall) of water into the atmosphere and this water is lost from the catchment. Australia experiences large annual and seasonal variations in rainfall. Water and catchment managers need to estimate how much water is transpired, especially as climate and land-use practices change, as this determines how much water is available for drinking, use in mining, forestry, irrigation, and for ecosystem health purposes. This project is the first to combine the use of scintillometry to compare spatially averaged rates of water use with development of a model to predict landscape water use. By using 4 contrasting ecosystems we shall provide a deep understanding of the controls of vegetation water use.

林地将大量（> 80%的降雨量）的水蒸发到大气中，这些水从集水区流失。澳大利亚的年降雨量和季节降雨量变化很大。 水和集水管理者需要估计蒸发了多少水，特别是随着气候和土地使用习惯的变化，因为这决定了有多少水可用于饮用，用于采矿，林业，灌溉和生态系统健康目的。该项目是第一个将空间平均用水率的比较与预测景观用水的模型的开发联合收割机结合起来的项目。通过使用4个对比鲜明的生态系统，我们将提供一个深入的了解植被用水的控制。
