Guidelines for the Design and Construction of Flexible Revetments Incorporating Geotextiles for Inland Waterways


Book Description

The particular emphasis is on the use of geotextiles as filters beneath the revetment cover layer. It is limited in scope to revetments constructed as part of inland waterways where waves and currents generated by ships and other vessels are the dominant loads.




Dikes and Revetments


Book Description

Low-lying countries, such as the Netherlands, are strongly dependent on good and safe sea defences. In the past, the design of dikes and revetments was mostly based on vague experience, rather than on general valid calculation methods. The demand for reliable design methods for protective structures has, in the Netherlands, resulted in increased research in this field. These contributions have been prepared by Dutch experts participating in the study groups of the Technical Advisory Committee on Water Defences. The book opens with an outline of general strategy and methodology on sea defences, illustrated in the following chapters by technical information on specific items and Dutch experience, and it ends with more general aspects such as probabilistic approach, integral (multifunctional) design, management & safety assessment. Together, these chapters provide an almost complete technical overview of the items needed for the design and maintenance of dikes and revetments. The enclosed CRESS-program allows for an initial estimation of hydraulic loads and preliminary design.




Environmental Design Guidelines for Low Crested Coastal Structures


Book Description

The effect of manmade activities is primarily local but can extend far away from the location of intervention. This underlines the importance of establishing coastal zone management plans covering large stretches of coastlines. In recent years, interest in Low Crested Structures (coastal defense structures with a low-crest) has been growing together with awareness of the sensitivity to environmental impacts produced by coastal defenses. The relation between wave climate, beach erosion, beach defence means, habitat changes and beach value, which clearly exists based on EC research results, suggests the necessity of an integrated approach when designing coastal protection schemes. In accordance with this need, the present design guidelines cover structure stability and construction problems, hydro and morphodynamic effects, environmental effects (colonisation of the structure and water quality), societal and economic impacts (recreational benefits, swimming safety, beach quality). Environmental Design Guidelines for Low Crested Coastal Structures is specifically dedicated to Low Crested Structures, and provides methodological tools both for the engineering design of structures and for the prediction of performance and environmental impacts of such structures. A briefing of current best practice for local and national planning authorities, statutory agencies and other stakeholders in the coastal zone is also covered. Presented in a generic way, this book is appropriate throughout the European Union, taking into account current European Commission policy and directives for the promotion of sustainable development and integrated coastal zone management. - Fills the gap between engineering and ecology in coastal defense planning - Shows the reader how to perform an integrated design of coastal defense schemes - Presents latest insights on hydro-morphodynamics induced by structures - Provides directly applicable tools for the design of low crested structures - Highlights socio-economic perspectives in coastal defense design




Recommendations of the Committee for Waterfront Structures Harbours and Waterways EAU 2004


Book Description

Since 1949 the "Committee for Waterfront Structures" has operated on honorary base as a committee of the Society for Harbour Engineering (HTG), Hamburg, and since 1951 also as working group of the German Society for Geotechnics (DGGT), Essen. Its full designation reads "Committee for Simplification an Standardization of Calculation and Construction of Waterfront Structures", which also outlines its goals. Following on from the previous joint publications, this new edition of EAU 2004 contains the safety concept with partial safety factors in accordance with the Eurocodes or the European prestandards as well as with the new edition of the corresponding German standard, partially differing on account of practice experiences. The recommendations continue to satisfy the requirements for international acknowledgement and application with regard to planning, design tendering, the awarding of contracts, building and building supervision. Further, the inspection and accounting procedures for harbour and waterway constructions are given from uniform points of view.




Coastal Engineering


Book Description

Effective coastal engineering is expensive, but it is not as costly as neglect or ineffective intervention. Good practice needs to be based on sound principles, but theoretical work and modelling also need to be well grounded in practice, which is continuously evolving. Conceptual and detailed design has been advanced by new industry publications since the publication of the second edition. This third edition provides a number of updates: the sections on wave overtopping have been updated to reflect changes brought in with the recently issued EurOtop II manual; a detailed worked example is given of the calculation of extreme wave conditions for design; additional examples have been included on the reliability of structures and probabilistic design; the method for tidal analysis and calculation of amplitudes and phases of harmonic constituents from water level time series has been introduced in a new appendix together with a worked example of harmonic analysis; and a real-life example is included of a design adapting to climate change. This book is especially useful as an information source for undergraduates and engineering MSc students specializing in coastal engineering and management. Readers require a good grounding in basic fluid mechanics or engineering hydraulics, and some familiarity with elementary statistical concepts.




Concrete in Coastal Structures


Book Description

Describing the nature of the marine environment and the effects of man-made structures on the behaviour of the sea, this books deals with hydraulic design, the material properties of concrete and the design and specification of structures for coastal environments.




Recommendations of the Committee for Waterfront Structures Harbours and Waterways


Book Description

The "EAU 2012" takes into account the new generation of standards, which is shortly to be introduced into the building control system; it consists of Eurocode 7, the associated national application documents and additional national regulations (DIN 1054:2010). In certain cases, partial safety factors are determined differently based on experience in practice. This means that the safety standard of sea and port buildings remains in place; the recommendations nevertheless satisfy the requirements for international recognition and application regarding the planning, design, specification, tender procedure, construction and monitoring, as well as the handover of - and cost accounting for - port and waterway systems under uniform criteria.




Hydraulic Structure,Equipment and Water Data Acquisition Systems - Volume III


Book Description

Hydraulic Structure, Equipment and Water Data Acquisition Systems is a component of Encyclopedia of Water Sciences, Engineering and Technology Resources in the global Encyclopedia of Life Support Systems (EOLSS), which is an integrated compendium of twenty one Encyclopedias. Hydraulic structures occupied a vital role in the development of civilization from the earliest recorded history up to the present, and undoubtedly will do so in the future. Humanity in ancient times settled mostly near perennial rivers, nomadic people frequented oases and springs, and to augment these natural ephemeral supplies, established societies built primitive dams and dug wells. This 4-volume set contains several chapters, each of size 5000-30000 words, with perspectives, applications and extensive illustrations. It carries state-of-the-art knowledge in the fields of Hydraulic Structure, Equipment and Water Data Acquisition Systems. In these volumes the historical origins, modern developments, and future perspectives in the field of water supply engineering are discussed. Various types of hydraulic structures, their associated equipment, and the various systems for collecting data are described. These four volumes are aimed at the following five major target audiences: University and College Students Educators, Professional Practitioners, Research Personnel and Policy Analysts, Managers, and Decision Makers, NGOs and GOs.




Restoring and Protecting Marine Habitat


Book Description

Tremendous changes have occurred this century in the nation's coastal habitats, in the way society views them, and in the way they are managed. This volume offers a complete, highly readable assessment of how scientific knowledge and coastal engineering capabilities can be more effectively used to protect and restore marine habitat. It addresses traditional and innovative uses of technology to protect remaining natural marine habitats, to enhance or restore those that have been altered, and to create marine habitat from lands used for other purposes. The use of dredged materials as a vital resource in protection and restoration work is explored. The book also explores organizational, management, and regulatory barriers to using the best available technology and engineering practice. Specific options for improvements are offered in each area.
