Prediction of evaporation from soil is an integral component of the water balance and performance of several important environmental engineering applications, including designing soil covers for restoration of large waste deposits or brown fields, estimating the dewatering rate of waste slurries (such as mine tailings), to altering soils or irrigation scheduling to minimize the severity of drought. Accurate prediction remains challenging due to the complexity of the physics at the soil surface. This project compares and contrasts a number of computer models used to predict evaporation, to each other and with new high quality data, to recommend guidelines for accurate use and improvement of such models.

土壤蒸发量的预测是水平衡的一个组成部分， 重要的环境工程应用，包括设计土壤覆盖物， 废弃物沉积或褐色区域，估算废弃物泥浆（如尾矿）的脱水率， 改变土壤或灌溉计划，以尽量减少干旱的严重程度。准确的预测仍然存在 由于土壤表面物理学的复杂性而具有挑战性。该项目比较和对比了 用于预测蒸发量的计算机模型数量，相互交流，并与新的高质量数据， 为准确使用和改进这些模型提出指导方针。
