Global and combined global-local response sensitivity analyses of uncertain structures based on model distance measures
The work reported in this thesis is in the area of global response sensitivity analysis (GRSA) of engineering systems in which the uncertainties associated with external actions and/or system parameters need to be explicitly ... -
An Integrated Choice and Latent Variable Framework to Incorporate the Influence of Travel Time Variability on Truck Route Choice
Route choice models (or path choice models) are useful for quantifying travellers’ preferences for or sensitivity to route attributes, predicting network-level traffic flows, examining the influence of information provided ... -
Modelling Hydrology of Upper Cauvery Basin Considering Changes in Climate and Landuse/Landcover
In the recent times, changes are noted in hydrological processes (e.g., surface runoff, lateral flow, infiltration, return flow, evapotranspiration, soil moisture and streamflow) in different river basins of the world due ... -
Development of Seismic Design Spectra For Shallow and Deep Soil Sites Considering Region Specific Parameters
Earthquakes are among the deadliest in all the natural disasters and have affected many people in the last few decades. The efforts to reduce or mitigate the impact of earthquakes have become increasingly focused upon ... -
Attenuation Characteristics and Seismicity Analysis of Himalayan Region with Linear Joint Time-frequency Analysis Techniques
About 59% of the land area of the Indian subcontinent has high chances of moderate to severe earthquakes, of which the Himalayas are the most seismically active. Regardless of the high seismic activity, the seismic network ... -
Extra-cellular Polysaccharides and Microbially Induced Carbonate Cementation Using Indigenous Microbes in Cattle Manure
Soft soils are composed of large portions of silts and clay and are characterized by low strength and high compressibility owing to their high-water content. Biocementation techniques are emerging as a strong alternative ... -
Hammer Energy Ratios of Different Spt Setups Using Indigenous Hammer Energy Measurement Apparatus
Standard Penetration Test (SPT) is carried using different components and lifting mechanisms, which causes variation in energy efficiency and the inverse relationship between energy transferred to drill rod and N value was ... -
GRACE-based Assessment of Climatic Controls on Hydrological Variables
Anthropogenic climate change is now well-established and is expected to have serious implications on Terrestrial Hydrologic cycle. This inspired scientific investigation to assess the impact of various climatic processes ... -
Fatigue Crack Growth in Roller-Rocker and Rocker Bearings of Railway Steel Bridges
Indian Railways comprise a major part of the infrastructure in India. Most of the transportation of raw materials, goods, and people from different parts of the country is done by the railways. To cope with the ever-increasing ... -
Spatial downscaling and analysis of satellite and ground-based rainfall for hydrological modelling
Precipitation is a vital element of the global hydrological and energy cycles, which is intermittent and highly variable in both space and time. Accurate measurements of precipitation at various space and time scales are ... -
Hydrologic Impacts of Climate Change : Detection and Attribution
Detecting, quantifying, and modelling the effects of human-induced climate change in regional hydrology is important for studying the impacts of such changes on the water resources systems as well as for reliable future ... -
Seismic Site Classification and Response Studies of Shallow Bedrock Sites
Among all-natural hazards, earthquakes are the most damaging in terms of loss of lives and damage to infrastructure. Amplification and liquefaction are the major effects of earthquake that cause massive damages to ... -
Modeling the Dependence Structure of Hydroclimatic Extremes
Analysis of extremes in a complex interacting hydroclimatic system is challenging due to rarity of events, small sample size, poor state of data or missing data, lack of statistical tools for analyzing observed changes and ... -
Hydrologic Inference: A Complex Systems Approach
The aim of this thesis is to understand linkages between hydrologic processes and patterns from the perspective of a complex system. In hydrologic systems, there exist interactions of hydrologic components among themselves ... -
Design Flood Estimation at Ungauged Locations using Geomorphological Characteristics
Estimates of design flood are necessary at locations of hydrologic structures (e.g., flood control dams, barrages) in studies related to their planning, design and risk assessment. In situations, where failure of hydrologic ... -
Weakly cemented granular materials: study at multiple length scales
Cemented granular systems are encountered at various scales in nature and artificially. We present an experimental study carried out on the structure and mechanical behaviour of weakly cemented granular materials. We study ... -
Hyperspectral Remote Sensing for Land Cover Classification and Chlorophyll Content Estimation using Advanced Machine Learning Techniques
In the recent years, remote sensing data or images have great potential for continuous spatial and temporal monitoring of Earth surface features. In case of optical remote sensing, hyperspectral (HS) data contains abundant ... -
Studies on Characteristics of Stabilized Soil Compacts for Structural Applications
Earth based construction materials are identified as green and low carbon materials. There are sustained R&D efforts in developing stabilised earth products for buildings and other structural applications. The thesis ... -
Probabilistic Analysis of Radionuclide Transport for Radioactive Waste Disposal Systems in Soil and Fractured Rocks
The safe management of radioactive waste disposal facilities is increasingly becoming a necessary condition for the future development of nuclear industry. To ensure long-term safety of these disposal facilities, performance ... -
Macroscopic modelling of heterogeneous, disordered road traffic flow
The groundwork for much of the existing traffic flow theory was laid in the 1950s and 1960s by researchers from developed economies like the United States. The car-following modelling approach, which is arguably the most ...
