Abstract. Steponas Kolupaila (1892–1964) was an important figure in 20th century hydrology and one of the pioneers of scientific water gauging in Europe. His research on the reliability of hydrological data and measurement methods was particularly important and contributed to the development of empirical hydrological calculation methods. Kolupaila was one of the first who standardised water-gauging methods internationally. He created several original hydrological and hydraulic calculation methods (his discharge assessment method for winter period was particularly significant). His innate abilities and frequent travel made Kolupaila a universal specialist in various fields and an active public figure. He revealed his multilayered scientific and cultural experiences in his most famous book, Bibliography of Hydrometry. This book introduced the unique European hydrological-measurement and computation methods to the community of world hydrologists at that time and allowed the development and adaptation of these methods across the world.

Steponas Kolupaila对水文科学发展的贡献

摘要。Steponas Kolupaila（1892–1964）是20世纪水文学的重要人物，也是欧洲科学测水的先驱之一。他对水文数据和测量方法的可靠性的研究尤为重要，并为经验水文计算方法的发展做出了贡献。Kolupaila是最早对水计量方法进行国际标准化的人之一。他创建了几种原始的水文和水力计算方法（他的冬季排放评估方法尤为重要）。他天生的才能和频繁出差使Kolupaila成为各个领域的通用专家和活跃的公众人物。他在他最着名的水文参考书目中揭示了他在科学和文化上的多方面经历。
