This study presents an systematic approach to water quality assessment, hybrid modelling and decision support for eutrophication management in deep reservoirs. It is found that during the summer monsoon the catchment runoff into the Yongdam reservoir induces a trandsfer of pollutants from a middle stratified layer to the surface layer. Although the transport mechanism limits nutrient accumulation on the bottom of the reservoir, it also offers an opportunity for on-going algae production in the surface water. Physically based modelling is used to understand the process of micro-scale turbulent mixing and its impact on the nutrient uptake by algae. Further, a data-driven model using clustering and partial least squares regression which uses results from a physically based model of the reservoir successfully predicts Chlorophyll-a concentrations.

This thesis presents the implementation of fully three-dimensional sediment transport and morphological updating formulations within a proven three-dimensional hydrodynamic flow solver. The thesis briefly discusses the formulations used to model both suspended and bed-load transport of non-cohesive sediment, and describes the implementation of a morphological updating scheme which incorporates novel approaches to morphological acceleration and dry bank erosion. Approaches used to model the three-dimensional effects of waves on coastal hydrodynamics and of three-dimensional currents on waves are also discussed. Results of several validation studies are presented and the model is shown to perform well in a series of simplified theoretical, laboratory, and full scale test cases. Application of the model and acceleration techniques to the complex and dynamic entrance to Willapa Bay, WA, USA is also discussed. Model processes are validated against the results of an extensive field measurement campaign, and diagnostic morphological model simulations are performed for two historical periods of contrasting morphological development. Input reduction and morphological acceleration techniques used to perform 5-year simulations of Willapa Bay are critically analysed and a new generic method to select a representative morphological tide for coastal environments containing significant diurnal tidal energy is presented.

Computer vision-based crack-like object detection has many useful applications, such as pavement surface inspection, underground pipeline inspection, bridge cracking monitoring, railway track assessment, etc. However, in most contexts, cracks appear as thin, irregular long-narrow objects, and often are buried into complex, textured background with high diversity which make the crack detection very challenging. During the past a few years, the deep learning technique has achieved great success and has been utilized for solving a variety of object detection problems. However, using deep learning for accurate crack localization is non-trivial. This book discusses crack-like object detection problem in a comprehensive way. It starts by discussing traditional image processing approaches for solving this problem, and then introduces deep learning-based methods. The book provides a comprehensive review of object detection problems and focuses on the most challenging problem, crack-like object detection, to dig deep into the deep learning method. It includes examples of real-world problems, which are easy to understand and could be a good tutorial for introducing computer vision and machine learning.

In this work, several modelling approaches are explored to represent spatial pattern dynamics of aquatic populations in aquatic ecosystems by the combination of models, knowledge and data in different scales.

It is shown that including spatially distributed inputs retrieved from Remote Sensing images, a conventional physically-based Harmful Algal Bloom model can be enhanced. Also, Cellular Automata based models using high resolution photographs prove to be good in representing aquatic plant growth. Multi-Agent Systems can capture well the spatial patterns exhibited in GIS density maps. A synthesis modelling framework was developed to include biological/ecological growth and diffusive processes, and local effects in conventional modelling framework. The results of the complementary modelling paradigms investigated in this research can be of help in achieving a sustainable environmental management strategy.

To determine the carrying capacity of a structure or a structural element susceptible to operate beyond the elastic limit is an important task in many situations of both mechanical and civil engineering. The so-called direct methods play an increasing role due to the fact that they allow rapid access to the request information in mathematically constructive manners. They embrace Limit Analysis, the most developed approach now widely used, and Shakedown Analysis, a powerful extension to the variable repeated loads potentially more economical than step-by-step inelastic analysis.
This book is the outcome of a workshop held at the University of Sciences and Technology of Lille. The individual contributions stem from the areas of new numerical developments rendering this methods more attractive for industrial design, extension of the general methodology to new horizons, probabilistic approaches and concrete technological applications."

This richly-illustrated reference guide presents innovative techniques focused on reducing time, cost and risk in the construction and maintenance of underground facilities:

A primary focus of the technological development in underground engineering is to ease the practical execution and to reduce time, cost and risk in the construction and maintenance of underground facilities such as tunnels and caverns. This can be realized by new design tools for designers, by instant data access for engineers, by virtual prototyping and training for manufacturers, and by robotic devices for maintenance and repair for operators and many more advances.

This volume presents the latest technological innovations in underground design, construction, and operation, and comprehensively discusses developments in ground improvement, simulation, process integration, safety, monitoring, environmental impact, equipment, boring and cutting, personnel training, materials, robotics and more. These new features are the result of a big research project on underground engineering, which has involved many players in the discipline.

Written in an accessible style and with a focus on applied engineering, this book is aimed at a readership of engineers, consultants, contractors, operators, researchers, manufacturers, suppliers and clients in the underground engineering business. It may moreover be used as educational material for advanced courses in tunnelling and underground construction.

Don't drain the swamp! Man's traditional response to swamps, marshes and bogs has been to drain them. But wetlands are not wastelands. Coastal marshes are among the world's most productive ecosystems. They make many commercial fisheries possible and protect coasts from floods and storm surges. Wetlands are pollution filters, water reservoirs. They are among the last wild places on earth, offering homes to endangered plants, birds and animals. Attitudes to wetlands are changing, but not fast enough. As scientists are documenting the wealth in wet places, governments and developers are draining them, damming them, logging them and building resort hotels where ', they once were. Destruction is usually a poor trade-off: well-managed wetlands in Louisiana are producing fortunes in seafood and timber. Waterlogged wealth examines the value of swamps and marshes, as well as the threats against them. In doing so it takes the reader to some of the world's most bizarre landscapes: the 'inland delta' of the Niger River in drought-stricken Mali; the wildlife-rich Okavango swamps of Botswana; the waterlogged Sunderban forests of India and Bangladesh, where tigers eat fish and crabs. Civilisation began around wetlands; today's civilisation has good reason to leave them wet and wild. Dr Edward Maltby is a lecturer in geography at the University of Exeter(UK). He has done extensive research on wetlands both in the North (UK, US, Canada) and the South (Fiji, Jamaica, India and the Falklands/Malvinas Islands). He is on the IUCN Wetland Programme Advisory Committee. Originally published in 1986

This monograph provides a comprehensive state-of-the-art description of the work carried out in the UK and Japan on "Flow and Sediment Transport in Compound Channels." It therefore describes research which has been conducted, primarily over the last two decades, and which has yielded a fairly detailed picture of the important behaviours of compound channels and produced a number of engineering prediction methods which ought to be widely adopted in practice. The text will inevitably highlight areas where our knowledge is sparse and it will spur others on in the task of filling in such gaps.
The concept of bi-national groups of researchers meeting together intermittently over period of some years, though not new, has drawn both inspiration and experience and the interaction has produced tangible outcomes in the form of this useful publication.

As a specialist in disaster preparation, you have huge responsibilities: a failure to prepare for natural and human-induced disasters costs lives and money. When a natural or human-induced disaster hits a built-up area the amount of damage it does will depend largely on the extent to which the built assets in the area were developed to withstand it. To fail in this respect is therefore both ethically and financially negligent. What kinds of structural and non-structural alterations can be made to protect buildings from large-scale disasters? How can we reduce the threat of these disasters, as well as the damage they cause? Presenting seven guiding principles, drawn from a broad range of disciplines and approaches, this book tackles the difficult questions about what can be done to attain built-in resilience. With contributions from many renowned experts and upcoming researchers in the fields concerned, it comprehensively assesses the wide range of issues faced by practitioners. Whether you're studying construction management, researching hazard resilience issues or working on construction projects in hazardous regions, this book is for you.
