✦ Synopsis
This paper presents a case study of landslide monitoring and evaluation at Okharpauwa, 19 km Chainage along Kathmandu -Trishuli highway in Nepal. An attempt has been made to predict slope movements using backpropagation neural network (BPNN). A Matlab-based BPNN model is developed, and the data from the case study are used to train and test the developed model to enable prediction of the magnitude of the ground movements with the help of input variables that have direct physical significance. An infiltration coefficient is introduced in the network architecture apart from antecedent rainfall, slope profile, groundwater level and shear strength of soil. A four-layered backpropagation neural network with an input layer, two hidden layers and one output layer is found optimal. The developed BPNN model demonstrates a promising result and fairly accurately predicts the slope movement.
