Numerical and statistical modelling for stabilisation of landslides

In the present paper an attempt has been made to find the maximum quantity of discharge of water flowing into the trench drain by two methods (i) through comprehensive diagram and (ii) through mathematical models. A comprehensive diagram for quantity of discharge of water flowing into the trench drain has been plotted from finite element solution for different anisotropic soil media, from which maximum quantity of discharge of water flowing into the drain corresponding to optimum spacing can be identified. In the second method mathematical models have been developed with the help of the numerical data on the maximum quantity of water flowing into the trench drain, the geometrical details such as depth, width, spacing of the trench drain and different types of soil conditions. The comprehensive diagram and the mathematical models will be of great use for developing guidelines for designing the trench drainage system within the anisotropic soil media for stabilising landslides.
