Cím:Study of the silting up process of the Mura river's floodplain in Hungary / Zsuzsanna Engi, Gábor Tóth, Mihály Braun, Katalin Hubay, Róbert Hercsel
Megjegyzések:The Mura River runs across the southwest edge of the Carpathian Basin, originating in Austria and forming a trans-boundary river between Slovenia, Croatia and Hungary. It's one of the region's significant rivers, its maximum discharge could reach 1600 m3/s. Complex water management arrangement did not happen due to historical changes of the state frontiers in the 20th century. The riverbed changes and floods require permanent attention that was increased by the last decades' extreme climatic amplitudes. Almost 300 m3/s volumetric capacity disappeared from the floodplain in the last 3-4 decade. The flood protection dikes aren't able to compete with this tendency, but their elevation would be very expensive. Its consequence is that the present floodplain's capacity isn't enough to conduct away the previous high discharge.The aim of the study was to determine precisely the rate of the floodplain's silting up or rather its tendency. The first step was the developing of the riverbed's historical reconstruction using GIS methods and then one sediment sampling location was fixed on this digital map. We examined more sections by exploratory drillings. Sample of the oxbow lake named Hosszúvíz was the most appropriate for the purpose of examination on the downstream part of Mura River, along the Croatian-Hungarian border. The paper detailedly describes the method and the results of sediment sampling and the analysis of the sediment sample in connection with recorded flood events.
