Title

THE STUDY OCCURRING AND FORMATION REASONS DEBRIS FLOWS IN SLOPE ALVAND NORTH HAMEDAN

Pages

  217-247

Abstract

DEBRIS FLOW is one of the most slope processes and material movement caues morphogens and increasing sediment load in rivers. This study aims DEBRIS FLOW in Northern Alvand SLOPES located in 15 Km distance far from Hamedan city by using aerial photograph and topography maps with 1:50000 and 1:25000 scales and ArcGis9 software. Total 44 samples from sample from DEBRIS FLOWs are randomly selected for morphometry parameters such as liner section flow, deeps section, core width, slope and HEIGHT using observation and measurement statistical real analysis regretion employing SPSS and Microsoft Excel software's. The deep section and slope volume debrises are modeled by deep erosion and weathering slope material measurement tool. Results showed that HEIGHT and slope are most important parameters in the effects parameters in caues DEBRIS FLOW in studied region. On the other hand, DEBRIS FLOW concen tration are spread in 2700-3000 m altitude shows lithology tectonic and nivation with perglaciear erosion system effects in formation and development of DEBRIS FLOW. In addition, the results if this study based on the Cain and Biljinberg formula reveled that occurring precipitation in 15 to 105 minute ranges in some year's caues DEBRIS FLOW motion in the SLOPES and subsequently inside the rivers, resulting in increasing sediment load in rivers and denudation SLOPES in studied region.
