Surface grain size variation within gravel bars: a case study of the River Opava, Czech Republic

Pages 13-20

Abstract

River basins are morphological manifestations of the earth’s surface and tend to be the focus of human activities and human population concentrations since the earliest human civilizations. This paper discusses a methodology that utilizes the combined use of different types of geomorphological hazards to describe the geomorphological hazard threat in the Zayandeh Rood Basin in Iran. Two major clusters of geomorphological hazards associated with tectonic and desertification processes were identified. The tectonic hazard parameters used in the analysis are magnitude, depth, faults zone and plate boundary activity. Whilst, the desertification hazard parameters are soil characteristics, climate quality, land use type, landform type, elevation and the location the sites.
