Summary

This bulletin published by the Department of Geology Tribhuvan University is a report on Toppling and wedge failures in the Malekhu River area. The kinematic analysis of discontinuities on the slope for evaluating the possibility of the landslide has indicated that the wedge failure is potential due to the presence of a line of intersection produced by the discontinuity parallel to the foliation of the right-side up layers and the overturned layers. This suggests that the toppled blocks may further slide. It is required to protect the slope from landsliding as there have been extended two unpaved roads one along the crown and the other along the toe of the landslide, and due to existence of the Malekhu Bridge in the downstream stretch of the river.
