Article
Rainfall-induced slope instability is one of the major concerns in tropical regions. Many rainfall-induced slope failures were observed in lateritic soil slopes in Kerala, during monsoon seasons. In the present study, an attempt was made to investigate the factors affecting the stability of soil slopes at the onset of rainwater infiltration; and to...
Article
Recirculation of leachate in bioreactor landfills accelerates the waste stabilization process. Due to biodegradation-induced changes in waste density, the waste parameters such as hydraulic conductivity and moisture retention characteristics (MRCs) evolve continuously within the landfill. In this study, an approach to evaluate the temporal variatio...
Article
The scarcity and fast depletion of granular materials necessitated to find alternative backfill materials in MSE walls. In the present study, application of construction and demolition waste (CDW) as a backfill for MSE walls was investigated. The physical, chemical, hydraulic and mechanical properties of CDW were found to meet the requirements of i...
Chapter
The frequency of rainfall-triggered landslides is increasing across the world. Infiltration of rainwater into the slopes with low permeable soil increases the pore water pressure and reduces the stability of slopes. Also, in the recent past, Kerala experienced many rainfall-triggered landslides. One of the most efficient way to prevent rainfall-tri...

In the present study, performance of geosynthetic reinforced MSE walls backfilled with locally available marginal lateritic soil at the onset of rainfall infiltration was investigated. Two different types of geosynthetics reinforcements were used. One was a conventional type of geogrids usually used in MSE walls, and the other was composite geogrid...
Chapter
Support systems in urban areas for temporary excavations are necessary to keep the sides of excavation nearly vertical, to minimize the excavation area and to ensure that the excavation is stable from stability as well as deformation criteria and will not lead to any damages in the surrounding area. In the present study, the paper discusses the cau...
Article
Reinforced soil walls are cost-effective alternatives to earth-retaining structures which can accommodate more settlements than conventional retaining wall systems. Ideally, freely draining granular materials such as sand are used as the backfills. But, scarcity of ideal granular materials necessitated the researchers to explore other alternatives....
Conference Paper
Major part of Kerala is covered with lateritic soil. Lateritic soils, in general, can withstand high stress under unsaturated conditions. However, during rainfall infiltration, there is a tendency that the lateritic soil may undergo large and sudden deformation. In the recent past, Kerala experienced heavy rainfall induced distress. Associated with...
