Graduated PhD Students

Dr. Veena U 


Dr. Veena completed her PhD defense on 1st June 2023. The title of her thesis is "Response of Natural Rubber Latex Treated Soils Under Static and Cyclic Loading". This study explores the suitability of Natural Rubber Latex (NRL) to be used as a soil stabilizer. Natural rubber polymer is well known for its binding properties, elongation capacity, tensile strength, and resilience. The present study investigates how these properties can influence various soil characteristics.

The modifications in strength and ductility of soils with three different plasticity characteristics were evaluated by conducting a series of unconfined compression tests on untreated and NRL-treated samples. The results demonstrated that NRL treatment does not improve soil strength substantially. However, an appreciable improvement in ductility was observed in treated samples. Another important objective of the study was to evaluate the potential of NRL in enhancing the cyclic response of cohesionless soil. It was found that impregnating sand with NRL improves its resistance to excessive cyclic degradation, thereby effectively mitigating the liquefaction hazard. The present study also identifies that the NRL treatment in the expansive soil would also help in controlling its volume change behaviour.

Dr. Ankit Tyagi 

Dr. Ankit Tyagi completed his PhD defense on 22nd August 2023. The title of his thesis is "Data Driven Spatio-Temporal Prediction of Landslide Susceptibility for the Himalayan Region". The current study focuses on accurate prediction of future landslide hotspot zones. Here, Dr. Tyagi has identified the key landslide causing factors and used them for predicting future landslide events.

The susceptibility maps generated in this study predict future landslide hotspot zones. The study region of Tehri, Uttarakhand state of India, was chosen for the research. Further, the Himachal Pradesh state of India and its two prominent landslide prone sites of Chamba and Bhuntar were used to validate the results. The results conclude that unplanned rapid urbanization will lead to an increase in landslide susceptibility in the future. The study also concludes that the change in climate scenarios will increase the intensity of the dynamic variables like rainfall and temperature, ultimately increasing the very high landslide susceptibility zone by 8%. As the forcing scenarios increase, the climate variables and landslide hotspot zones also increase for the year 2050. These accurate prediction of landslide zones and their future projections can help land use policymakers restrict the urbanization growth in high landslide risk zones and ensure sustainable development. Further, these results can be used to revise current land use policies and develop mitigation measures for Landslide Risk Reduction (LRR).
