Abstract

The Study of Morphological Change and Speed of Landslide Displacement. The extent of instability can be determined., The extent of instability can be determined. The aim of this study was to model the speed of displacement and change the morphology of the marshland Landslide in the northern slopes of Alvand, Hamadan, using Morphometric Indices, the GAMBIT pre-processor model, and the FLUENT computing model. First, The coefficient of transverse, longitudinal and deformation of Landslides was investigated. Then the fluid properties were measured and calculated based on the slope and Reynolds numbers, speed and how to change the Landslide morphology for 0, 50 and 100 seconds. The results of Morphometric Indices showed that the slope and water angle has a significant effect on lateral expansion and transverse Landslide shape variation. Studies on Landslide morphology evolution show that the Landslide of the longitudinal deformation is very weak and then a weak transverse deformation has occurred. Results of calculation of Reynolds equations. In the Fluent model, it shows that the initial motion and deceleration of the Landslide mass under the influence of the gravity and the velocity of the first seconds of motion in the longitudinal shape and in seconds 50 in the form of not too transverse and after the time and with the reduction of the gravity and the effect of 100 in the shape of It is completely transverse and lateral. The results show that the higher the viscosity of the Landslide mass, the more intense the formation of fungal fossils forms, and with increasing the flow rate of the fluid volume and the change in its morphology, the increase of the lateral mass also in the pine increase. Also, the results of the Fluent and Field model and the results of the indicators are completely consistent with the results.
