Methods for calculating sediment transport in the Drava River River sediment transport plays a vital role in shaping river morphology, and it also influences different flow patterns and creates diverse ecosystems along the river course. The most important factors affecting sediment transport are: flow speed, size and composition of sediment, shape and roughness of the river bed, and the amount of sediment in the upstream parts of the basin as well as the presence of obstacles and changes in the river flow. The Drava River transports large amounts of suspended and bed load in its flow through Central and South - Eastern Europe. In this paper the hydrological, geological and hydrogeological characteristics of the Drava River and the types and importance of sediment in the River are explained, and an overview of methods for calculating suspended sediment transport in it are given. In the paper, data from four hydrological stations on the Drava River were analyzed, and they are : Varaždin, Donja Dubrava, Botovo and Terezino Polje. The long-term distribution of water level, flow and sediment transport and their connection with climatic (precipitation) and anthropogenic (hydroelectric power plant construction) factors are presented. The methods of suspended sediment transport calculations are shown on the example of the Drava River, and they include: calculation of the concentration of suspended sediment based on discrete water samples, calculation of the average profile concentration and determination of the correction coefficient for daily discrete samples, calculation of daily, monthly and annual sediment transport for the measuring station Botovo, definition of the sediment curve at the measuring stations on the Drava River, trends of changes in the sediment transport regime depending on anthropogenic and climatic influences as well as the description of the bed load transport calculation methods with an example of calculation based on Einstein – Brown method.
