Abstract


The developed models leave the ground of discussion for their accuracy, reliability and practicability for different school of thoughts. The traditional ways have been used in past to develop landslide risk models. As in this research, the conceptual model has been developed using various combined previous landslide risk algorithms, criteria and parameters. The hypothesis was also built initially based on the consideration of the topographic situations, geophysical properties and previous landslide records to develop this conceptual model. This model has utilized qualitative technique by assigning the different weight to the different parameters for developing different levels of risk. The weight assigned weight known as comparison matrix method remains subjective, so in this regard, the  experts opinions and saaty scale of importance method has been used to cover the subjectivity of the selected criteria. The utilization of Geographical information systems (GIS) techniques and remotes using their various sub techniques have been applied for preparation of this conceptual model. It is assured that this type of developed composited algorithm, criteria conceptual model will assist to the different model developers for development for accurate, reliable, and implementable landslide risk models which can be helping for the different decision makers in the field during implementing them.
