Estimation of Daily Actual Evapotranspiration using Microwave and Optical Vegetation Indices for Clear and Cloudy Sky Conditions
(2018-05-25)Evapotranspiration (ET) is a significant hydrological process. It can be studied and estimated using remote sensing based methods at multiple spatial and temporal scales. Most commonly and widely used remote sensing based ... -
Estimation of Root Zone Soil Hydraulic Properties by Inversion of a Crop Model using Ground or Microwave Remote Sensing Observations
(2018-02-09)Good estimates of soil hydraulic parameters and their distribution in a catchment is essential for crop and hydrological models. Measurements of soil properties by experimental methods are expensive and often time consuming, ... -
Experimental and Analytical Studies on Damage Detection and Failure Analysis of Transmission Towers and Tower like Structures
(2017-12-07)The transmission line (TL) tower is an important component in electrical network system. These towers consist of members (angle sections) and connections (bolted connections) plus foundation, which act together to resist ... -
Experimental Studies on The Mechanical Behaviour of Cohesive Frictional Granular Materials
(2017-09-26)Thss thesis presents the results of an experimental programme on the static mono-tonic response of cohesive-frictional granular materials. The purpose of this experimental programme was to gain insight into the mechanical ... -
Factors Controlling the Dispersivity of Soils and the Role of Zeta Potential
(2017-12-07)Most soil particles loses cohesion and split up the soil mass into individual soil grains when they come in contact with water and get saturated. In dispersive soils the particles detach more spontaneously from each other ... -
Factors Influencing Contaminant Transport in Vadose Zone of Near Surface Radioactive Waste Disposal Facility
Radioactive waste is generally classified as low and intermediate level waste (LILW) and high-level waste (HLW), based on their level of radioactivity and the time taken for decay. The low and intermediate level ... -
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 ... -
Field Investigations And Modeling of Flow in Vadose Zone in a Forested Watershed
(2017-10-18)The vadose zone is the unsaturated zone between the ground surface and water table. This zone is of much importance as it acts as a link between surface water and ground water. Knowledge of soil moisture in this zone is ... -
Finite Element Limit Analysis for Solving Different Axisymmetric Stability Problems in Geomechanics : Formulations and Solutions
(2017-11-15)Limit analysis is a very powerful tool to find accurate solutions of several geotechnical stability problems. This analysis is based on the theory of the plasticity and it provides two limiting solutions within lower and ... -
Fracture Behaviour including Size Effect of Cement Stabilised Rammed Earth
(2018-01-30)Rammed earth is a monolithic construction formed by compacting processed soil in progressive layers. Rammed earth is used for the construction of load bearing walls, floors, sub base material in roadways, airport runways, ... -
A Framework to Measure the Socio-Economic Impact of Development Programs Using Malmquist Index
(2018-06-08)The main objective of this research is to evaluate the socio economic impact of the development programs like MGNREGA, JnNURM and development of Roads project, on the intended target area. The entire thesis can be divided ... -
Fuzzy State Reservoir Operation Models For Irrigation
(2017-05-04)Efficient management of limited water resources in an irrigation reservoir system is necessary to increase crop productivity. To achieve this, a reservoir release policy should be integrated with an optimal crop water ... -
Geotechnical Behaviour Of Soil Containing Mixed Layered Illite-Smectite Contaminated With Caustic Alkali
(2008-01-29)The aim of the thesis has been to evaluate and understand the effect of caustic alkali solution of varying composition on the behaviour of expansive soil containing mixed layered minerals. Mixed layered minerals are formed ... -
Ground Improvement using 3D-Cellular Confinement Systems : Experimental and Numerical Studies
(2018-01-09)The various aspects of the 3D cellular confinement systems (geocells) subjected to static loading are comprehensively studied with the help of experimental and numerical studies. The performances of the geocells were ... -
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 ... -
