Opis: Managing sediment transport in streams is crucial to the surface water resource development strategy and has several implications for flood risk and water management, hydropower use, and balancing river morphology. This paper summarises the movement and behaviour of suspended sediment within the Slovenian portion of the River Drava, covering a span of thirteen years from 2005 to 2018. An analysis of relevant data collected during this period is also presented. Suspended-sediment dynamics strongly depend on flow velocity, seasonal variations in sediment sources, and human interventions in the riverbed. The transportation of material in the River Drava results in the accumulation of sediments in reservoirs and riverbeds, consequently impeding the natural hydrological cycle by reducing the outflow into aquifers. The 2018 high-water event is analysed in terms of the dependence of concentration of suspended sediments on discharge, where counterclockwise hysteresis was observed, providing an essential clue to the origin of sediment. Sediments from the River Drava in Slovenia are managed with some conventional processes and are mainly deposited or reintegrated into rivers and aquatic ecosystems. Some additional sediment management strategies with long-term solutions for efficient and comprehensive water management, hydropower, and ecological problems are proposed.

Opis: The pollution of rivers, endangered underground water and water springs, hazardous substances in the soil, uncontrolled disposal of large quantities of waste - these and many other problems severely reduce the quality of life and hinder the country's overall development. The majority of surface water courses are excessively polluted (29% fall into the third and fourth water quality class). The pollution is spreading towards river sources. The quality of groundwater has been deteriorating recently. It is evident from the "Strategy for Economic Development" of Slovenia that the approximation to the European Union is the right choice for Slovenia.
