Integrated approach for determining spatio-temporal variations in the hydrodynamic factors as a contributing parameter in landslide susceptibility assessments

摘要: Although general approaches to the effect of water on mechanisms causing landslides have been adopted, work presented in this paper was carried out quantify landslide susceptibility variation space and time, integrating soil moisture distribution routing (SMDR) model concept. The approach proposed present study reflects temporal effects saturation degree index (SDI) as a new understand saturation. topographic wetness (TWI) is conventional parameter that represents relative landsliding. used area emergence Derebasi area. comparative results maps obtained from utilizing SDI TWI are remarkable. Accordingly, substantial method using attainable monthly mean meteorological data generate maps. for validated with other has occurred same watershed. revealed compatible mechanism may help express analyses.
