Title

INVESTIGATING THE ROLE OF EFFECTIVE MORPHODYNAMIC AND CLIMATIC FACTORS IN THE EMERGENCE AND DEVELOPMENT OF DEBRIS FLOW IN CENTRAL ZAGROS

Pages

  61-82

Abstract

DEBRIS FLOW is one of the most important processes in material displacement, which causes the formation and increase of sediment loads of rivers. In order to investigate the DEBRIS FLOW in the northern slopes of Alvand in CENTRAL ZAGROS, 44 samples of DEBRIS FLOWs are selected randomly and morphometric parameters such as liner section flow, highs, deeps section, core width, slope were calculated using observation and measurement statistical real analysis regression by aerial photograph and topography maps with 1: 50000 and 1: 25000 scales and ArcGIS9. Effective climatology parameters on debris including rain, snow and temperature were studied using 10 stations in the region (1991-2010). The study shows that the effects parameters on DEBRIS FLOW are altitude and slope in northern alvand slopes. But, the DEBRIS FLOWs are spread in 2700-3000m altitude indicates the important role of lithology, tectonic and snowfall factors along with the glaciation and erosion system of the glacial side in the formation and development of regional debris. The study of precipitation effects through the Cain and Biljinberg formula show that rainfall of 15 to 105 minutes in some years caused DEBRIS FLOW motion on the slopes entering the rivers and increase their sediment load.
