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 ...
Mechanics of Drilling in Porous Brittle Solids
(2018-01-01)
This thesis presents a detailed experimental programme on understanding the mechanics of drilling in porous brittle solids. Gypsum was used as a model material for this experimental study, in which the mechanics of drilling ...
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 ...
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 ...
Schemes for Smooth Discretization And Inverse Problems - Case Study on Recovery of Tsunami Source Parameters
(2017-10-17)
This thesis deals with smooth discretization schemes and inverse problems, the former used in efficient yet accurate numerical solutions to forward models required in turn to solve inverse problems. The aims of the thesis ...
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 ...
Partial Slip Contacts in Linear Viscoelasticity
(2017-10-05)
This work analyzes partial slip contact problems in the theory of linear viscoelasticity using both the semi-analytical method and nite element method. Such problems arise in metal-polymer contacts in orthopedic implants ...
Quantification of Uncertainties in Urban Precipitation Extremes
(2018-05-25)
Urbanisation alters the hydrologic response of a catchment, resulting in increased runoff rates and volumes, and loss of infiltration and base flow. Quantification of uncertainties is important in hydrologic designs of ...
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 ...
