An alternative model of retaining walls on sandy area to prevent landslides

On a Numerical Model for Gasification of Biomass Materials: An Alternative Method to Combustion

In this paper, a thermochemical equilibrium model is used to predict the performance of a downdraft biomass gasifier. Numerical results are shown to be in good agreement with those of the experiments. Different biomass materials are tested using the model, and forest residual is shown to be the most energetic one. For this material, the gasification temperature, syngas composition and calorific...

Active tectonics of the Roudbar region: with special reference to the landslides of the area

The population of Rudbar in northern Iran, is due to Steep slopes of topography, Sloping Loose Materials, active tectonic phases, Construction of roads and railways, from areas prone to landslide events .In this reaserch, in the first phase, based on ground surveys, a geologic map of 1: 25,000, satellite images and  other data of Rudbar region, range and status of landslides of the region were ...
