Mountain river dominant formative discharge evaluation (through example of the Upper Tisa basin)

Abstract

Based on the comparative analysis of the two most commonly used techniques for the definition of dominant formative discharge for the Upper Tisa river, it has been established that technique by M.I. Makkaveyev can be used provided the availability of fixederm discharge measurements or by means of the transition regional factors. Transition figure between the average daily rate and fixed-term discharge is recommended, which provides an opportunity to obtain reliable values of the dominant formative discharge in the full range of flow intensity change with low error (less than 10%).
