SUSPENDED SEDIMENT TRANSPORTATION IN SLOVENE RIVERS

Abstract

The Agency RS for the Environment carries out monitoring of the transport of suspended sediment in Slovene rivers. The total amount of transported suspended sediment in the river profile on the Mura in Gornja Radgona in a 50-year period exceeded 32.6 million tons. We recorded the most transport in 1972, when the River Mura carried some 4.7 million tons of suspended sediment through the profile in a single year. The Savinja carried 10.5 million tons through the profile in 50 years. The exception was 1997, when the annual quantity reached 1.3 million tons, which is 12.6% of the amount transported in the entire period of observation. The catchment area of the hydro-measurement station at Veliko Širje is considerably smaller, so an interesting conclusion is that with similar hydrological conditions, the surface of the Savinje river basin has fallen by 70 mm over a thousand years, and the surface of the Mura river basin only by 21 mm.
