摘要

蒸发蒸腾作用是径流模型中使用的一个关键参数。Bulango Ulu 大坝位于赤道附近，全年日照最充足，因此蒸散量是分析水资源可用性的关键因素。本研究旨在分析两种蒸散量计算方法对 Bulango Ulu 大坝径流建模准确性的影响。研究采用修改后的彭曼蒸发蒸腾法和索恩斯韦特蒸发蒸腾法作为莫克模型的输入。分析表明，Mock-Penman 方法优于 Mock-Thornthwaite 方法，统计参数结果为 MAE 0.963、NSE 0.891、R 0.949 和 Kr 1.3%。

Analisis Evapotranspirasi Metode Penman Modifikasi Dan Thornthwaite Terhadap Pemodelan Debit Fj. Mock

Evapotranspiration is a key parameter used in run-off modelling. The Bulango Ulu Dam, located near the equator where sunlight is at its peak throughout the year, makes evapotranspiration a crucial factor in analysing water availability. This research aims to analyse the performance of two evapotranspiration calculation methods on the accuracy of run-off modelling to the Bulango Ulu dam. The study employs the modified Penman and Thornthwaite evapotranspiration methods as input to Mock's model. The Analysis indicates that the Mock-Penman method outperforms the Mock-Thornthwaite method, with statistical parameter results of MAE 0.963, NSE 0.891, R 0.949 and Kr 1.3%, Therefore, it concludes that the run-off modelling aligns with the observed flow value
