Reservoirs are the key infrastructure of water resources management. A controlling variable of reservoir operation is evaporation, which in semi‐arid and arid regions may consume a large fraction of reservoir storage annually. This paper assesses the role of evaporation and the choice of evaporation methods on reservoir operation. The operation of the reservoir is calculated with the standard operation policy (SOP). Several efficiency criteria are employed to rank the evaporation‐calculation methods with the technique for the order of preference by similarity to ideal solution (TOPSIS). The method presented in this paper is illustrated by applying its application to Karkheh reservoir, the largest in Iran.

蒸发估算储水损失的方法比较及其对水库管理的影响

水库是水资源管理的关键基础设施。储层运行的控制变量是蒸发，在半干旱和干旱地区，蒸发可能每年消耗大量的储层。本文评估了蒸发的作用以及蒸发方法在油藏运行中的选择。储层的运行是根据标准运行策略（SOP）计算的。采用几种效率标准对蒸发计算方法进行排序，以与理想解决方案（TOPSIS）相似的方式对优先顺序进行排序。本文将其应用于伊朗最大的Karkheh水库进行了举例说明。
