The main objective with this literature survey is to elucidate the state of the art of internal erosion in embankment dams in order to be able to formulate a research program for numerical modelling of internal erosion in a physically sound manner. Since these processes normally are localised to specific zones in a dam, the ordinary continuum approach frequently utilised in soil modelling will not, by itself, be successful. The plan of the research group is therefore to treat internal erosion numerically as a type of localisation and describe the constitutive behaviour with micromechanical models in localised zones.
In the next step, the internal erosion model developed will be implemented in a mathematical consistent fashion in a continuum model, based on e.g. the finite element method. In such software, ordinary computations of stresses, strains, deformations and pore pressures in an embankment dam can be performed; results which possible lead to conclusions about the initiation of internal erosion processes. When internal erosion is initiated, the micromechanical models will describe these processes in localised zones.

Soil Behaviour and Critical State Soil Mechanics
Author: David Muir Wood
Paperback: 488 pages
Publisher: Cambridge University Press (April 26, 1991)
Language: English

Description
Soils can rarely be described as ideally elastic or perfectly plastic and yet simple elastic and plastic models form the basis for the most traditional geotechnical engineering calculations. With the advent of cheap powerful computers the possibility of performing analyses based on more realistic models has become widely available. One of the aims of this book is to describe the basic ingredients of a family of simple elastic-plastic models of soil behavior and to demonstrate how such models can be used in numerical analyses. Such numerical analyses are often regarded as mysterious black boxes but a proper appreciation of their worth requires an understanding of the numerical models on which they are based. Though the models on which this book concentrates are simple, understanding of these will indicate the ways in which more sophisticated models will perform.

Sciences of Geodesy - I: Advances and Future Directions By Guochang Xu
* Publisher : Springer
* Number Of Pages: 507
* Publication Date : 2010-11-29
* ISBN-10 / ASIN : 3642117406
* ISBN-13 / EAN : 9783642117404
Product Description:
This reference and handbook includes contributions from the world’s leading experts and describes the history, theory, development, research highlights, problems and future of the individual geodetic fields. The subjects include: Geodesy, Satellite Geodesy, Marine Geodesy, GPS / Galileo Systems, Navigation and Positioning, Aerogravimetry, Super-conducting Gravimetry, Adjustment and Filtering, Orbits Theory, Orbits Determination, Tectonics, Earth Rotation and Polar Motion, Earth Tide and Ocean Loading Tide, Satellite Altimetry, Remote Sensing, InSAR, etc.
Chapter 1 “Absolute and Relative Gravimetry” provides an overview of the
gravimetric methods to determine most accurately the gravity acceleration at given
locations.
Chapter 2 “Adaptively Robust Kalman Filters with Applications in Navigation”,
the main achievements of the adaptively robust filter are summarized from the published
papers in recent years.
Chapter 3 “Airborne Gravity Field Determination” outlines some of the basic
principles of airborne gravimetry, with special focus on geodetic applications, and
gives some examples from recent large-scale surveys.
The Chap. 4 “Analytic Orbit Theory” describes the satellite orbit theory in a condensed
way. The perturbed equations of satellite motion are discussed first.
The Chap. 5 “Deformation and Tectonics” addresses some aspects of the use
of the GPS system in the study of plate tectonics.
Chapter 6 “Earth Rotation” provides an overview of the state-of-the-art theoretical
and observational aspects on Earth rotation.
Chapter 7 is entitled “Equivalence of GPS Algorithms and its Inference”. The
equivalence principle of differential and un-differential GPS algorithms, combined
and un-combined GPS algorithms as well as their mixtures are discussed.
Chapter 8 “Marine Geodesy” presents an overview of geodetic contributions to
the scope of the marine environment.
Chapter 9 “Satellite Laser Ranging” introduces the reader to this space geodetic
technique and covers the basics of instrumentation, error sources both in the measured
and in calculated range, leading up to determination of observed-computed
residuals, which provides an indication of “best-fit” orbit to the observations.
Chapter 10 “Superconducting Gravimetry” is related to measuring, evaluation
and interpretation of superconducting gravimeter data.
Chapter 11 “Synthetic Aperture Radar Interferometry” introduces the principles
and data processing of the SAR interferometry including differential SAR interferometry,
corner reflector SAR interferometry (CR-INSAR) and some of the practical
applications.

Summary
For many transportation systems, the cost of expanding the infrastructure is too high. Therefore, the focus must shift to improving the quality of transportation within the existing infrastructure. The second edition of a bestseller, Intelligent Transport Systems: Smart and Green Infrastructure Design critically examines the successes and failures of intelligent transportation systems (ITS) during the course of the past decade. The new subtitle reflects this edition’s focus on meta-principles critical to moving ahead and successfully building ITS infrastructures that take advantage of smart/green technologies. The book identifies challenging problems that must be addressed in order to bring real quality of life improvements and positively impact our environmental and civil infrastructure systems.
New in the second edition:
* Coverage of new, efficient green strategies
* Critical review of important developments and implementation of ITS
* Discussion of how to apply new insights and meta-principles to real-world ITS problems
The authors argue strongly for the need to incorporate innovative and creative approaches to transportation problems, based on the fundamental principles and thorough scientific validation. They stress the need for computer modeling and simulation of a representative system to help design and validate such complex, large-scale systems, and the design of new performance metrics to estimate the performance of these systems. They provide a radically different approach to transportation systems design—one that closely resembles reality and promises to yield an architecture that delivers the highest efficiency.
