Some studies on volume change and strength behaviour of soils as affected by environmental factors
The present investigation is an attempt to understand clay–organic pore fluid interactions, to check in the first place whether highly ligative organic molecules result in clay behaviours similar to those produced by weakly ... -
Axisymmetric problems on capacity and passive earth pressures in soils with bilinear ground surface by the method of characteristics.
Shallow footings are placed on different types of soil under different site conditions. A shallow footing placed in a depression with stratified soil is a good example of a practical problem. For a realistic analysis of ... -
Prediction of rainfall state using a hidden state Markov model
ainfall prediction is a challenging problem because of the various uncertainties involved in rainfall processes. Nevertheless, long-term prediction of rainfall state is of great significance for the planning and management ... -
Quantification of uncertainties in urban precipitation extremes
Urbanization alters the hydrologic response of a catchment, resulting in increased runoff rates and volumes, and loss of infiltration and base flow. In general, quick runoff response to precipitation extremes due to short ... -
Analytical and numerical modelling of complex multiphase flow processes in geological environments
Most geological flow and transport models describe the flow and convective-dispersive spreading of one or more components entirely dissolved in the most common geological fluid, water. However, many other processes—such ... -
Two Dimensional Numerical Modelling Of Variably Saturated Flows ?
The prediction of moisture and contaminant transport through unsaturated soil to groundwater is becoming increasingly important in the fields of hydrology, agriculture, and environmental engineering. Computer-aided simulation ... -
Study of the rainfall-runoff models using regression and optimization techniques
Various models representing the rainfall-runoff relationship have been in existence and are also being modified. Some of them incorporate various intermediate processes. The majority of the existing models require continuous ... -
VENTURI STUDIES WITH WATER ON CAVITATIOK INCEPTION CAVITY CHARACTERISTICS AND CAVITATION EROSION BEHIND BLUFF BODIES
Cavitation is defined as the formation, growth and collapse of vapour or gas? and vapour?filled bubbles in a liquid subjected to reduced pressures (of the order of the vapour pressure of the liquid) at constant ambient ... -
Analytical and experimental studies on stratified flows
Stratified flows are the fluid motions caused or influenced by the density differences. The density currents, the intrusion of salt wedge, the gravitational circulation, diffusion and dispersion of pollutants in estuaries ... -
Global response sensitivity and reliability analyses of structural dynamical systems with parameter and excitation uncertainties
This thesis develops computational methods for global response sensitivity analysis (GRSA) and time-variant reliability analysis in structural dynamical systems with parameter and excitation uncertainties. The primary ... -
Studies on simple and restricted orifice surgre tanks
This thesis deals with certain basic experimental studies conducted on the phenomenon of mass oscillations in restricted orifice surge tanks. Simple surge tanks were also studied, they being considered an extreme case of ... -
Some characteristics of branch channel flow
This thesis comprises three parts. The first part contains literature survey, the second part the theoretical analysis, experimental verification and results, and the third part the development of a precision point gauge. ... -
Cavitation and cavitation damage
This thesis deals with the study of certain aspects of cavitation damage. In the first part of the thesis, a critical survey of the existing literature has been made, and various theories of cavitation damage have been ... -
Some Studies on branch channel Flow
In the present investigation, methods are suggested to predict the flow into a branch taking off from a main channel, maintaining subcritical flow in the main and supercritical in the branch channel. The methods are based ... -
Experimental studies on swirling flows at vertically upward intakes
The experimental investigations presented in this thesis are concerned with the aspects of sump geometry and sump parameters, which govern the flow conditions at vertically upward intakes. Detailed studies are made to ... -
Flow characteristics of sharp-edged orifices,quadrant-edged orifices and nozzles
This thesis presents an integrated study of flow past sharp-edged orifices, quadrant-edged orifices and long radius nozzles, covering different aspects such as metering characteristics, loss characteristics and flow ... -
Studies on erosion due to liquid jet impingement
The problem of erosion due to liquid jet impingement and cavitation is gaining importance with the rapid technological progress in the recent years. The possible uses of liquid jets in the mixing processes in chemical ... -
Data-Driven Prediction of Concrete Behaviour and Performance Enhancement Through CO₂ Inclusion Techniques
Concrete remains the most widely used construction material globally, valued for its versatility, strength, and durability. However, the conventional approach to concrete mix design, governed by empirical codal provisions ... -
Advanced Thermomechanical Modeling of Soft Matter Systems
This thesis deals with advanced thermomechanical modeling of complex soft matter systems, including polymers, gels, and biological tissues. It addresses a few fundamental limitations of classical theories, such as the ...
