Og stormfloden komEn historisk roman om stormfloden i 1872.Bogen handler om menneskets kamp mod havet, om bøndernes hårde slid med at grave grøfter og bygge diger i et forsøg på at fravriste land og muld fra det salte vand, der hele tiden siver ind over markerne og slår afgrøderne med misvækst. Gennem fire slægtled får vi oprullet historien om 1800-tallets mange forsøg på at indvinde jord fra Rødby Fjord.Romanen starter i 1808, hvor Reventlowfamilien omplanter to dygtige fæstebønder, Otte og Jerk, fra Als til Lolland. Sammen med deres familier giver Otte og Jerk sig i lag med det hårde arbejde i marken, og som årene går lykkes det for dem at gøre jorden mere frugtbar.Samtidig arbejder rige købmænd med store planer om at inddæmme og tørlægge hele fjorden – planer der møder modstand hos småbønder og fjordfiskere, der ser deres livsgrundlag truet. Den 13. november 1872 kommer stormfloden, der slår alle bestræbelser og drømme omkuld, men sætter liv i nye. I bogens sidste del fortæller ingeniøren Nikolaj Ottesen, Otte-slægtens 4. generation, om sit bidrag til den endelige tørlægning af Rødby Fjord i 1929.Og stormfloden kom er en barsk og bevægende roman om mennesker og deres livtag med naturens kræfter, om historiens hjul, der med nye kræfter ruller hen over gamle slægters møjsommeligt tilkæmpede landvindinger.

Den lille, men vægtige, roman handler om digebyggeren Haike Hauens kamp mod naturen, med ham selv og med det omgivende samfund ved marsklandet i Sydslesvig, der lever i en evig angst for at blive opslugt af havet. En kamp mellem naturens mytologiske kraft og det rationelle menneskes forsøg på at bekæmpe den. Thomas Mann kaldte Theodor Storm ”en mester”. Nu genudgives hans hovedværk Skimmelrytteren, der samtidig er en klassiker i den tyske litteraturhistorie, på dansk. Bogen regnes til den tyske realisme, men har fået fornyet aktualitet i kraft af sin skildring af menneskets naturforhold og kamp mod stigende vandmasser.Theodor Storm levede 1817-1888 i Nordtyskland. Født i Husum, hvor han også senere vendte tilbage som advokat og forfatter.

Velkommen ombord på tidsmaskinen, der i form af denne bog tager læseren med på en rejse i ord og billeder tilbage til Rønne havn i 1960’erne. Her er mulighed for at se de gamle kajer, havneanlæg, bygninger og ikke mindst de kønne og specielle skibe, som lagde til i havnen i forbindelse med fiskeri, havneudvidelser, fragt- og passagersejlads. Meget er ændret siden dengang men ikke mere end, at man - ved synet af de mange samtidige fotografier i bogen - tænker: "Jamen, det var jo lige i forgårs". Vi ønsker en behagelig havnevandring.

The book is based on stochastic theory of sediment motion, particularly the theory of transition intensities.It provides a complete theory and equation system of non-equilibrium transport of non-uniform suspended load. The content proposed theory reports, for the first time in literature, the general boundary condition of diffusion equations of non-equilibrium transport with transition intensities. The book also introduces the theoretical expressions of size distribution of the carrying sediment capacity, efficient bed material grade, and saturation recovery coefficientThis book describes the application of non-equilibrium transport theory and provides solutions to some long-standing unsolved controversial problems related to sediment transport. It establishes a generic mathematic model of reservoir sedimentation and river channel evolution; illustrates the same transport regulars of wash load and bed material load; demonstrates the multi-valued nature of carrying-sediment capacity and its single-valued consideration; and describes the mechanism of bed material coarsening. This book is of interest to a wide audience including students, technicians, and academics, primarily working in the field of river hydra-dynamics. In addition, this book receives attention from the research community working in fields, such as hydrogeology, hydraulic engineering, river navigation, wastewater treatment, and environmental protection

David Topp succinctly explains how a city built on a flood plain will never be flood free.- Peter Spearritt: Emeritus Professor of History, The University of Queensland.Brisbane Breached: The Story of a Drought Defaulted Floodplain delves into the intricate historical chronicles of Brisbane, meticulously exploring the city's enduring struggle against the dual forces of severe flooding and prolonged droughts.The narrative unfolds, juxtaposing the recurrent major flood events between 1841 and 2022 with intermittent, yet impactful, periods of drought. Such occurrences, inherently linked to Brisbane's geographical position constructed within a flood plain, present profound policy challenges that have persisted over time.In dissecting the prevailing beliefs in the efficacy of dam constructions as a panacea for Brisbane's water-related vulnerabilities, this book confronts the prevailing misconceptions. The inadequacies of solely relying on dam infrastructure become apparent in the face of the city's unique topographical limitations, prompting a necessary paradigm shift in policy considerations.Foreseeing an imminent population surge, projected to add one million residents by 2032, this book's discourse posits the urgency of transcending traditional water management strategies. This paradigmatic shift becomes a pivotal policy proposition to avert the existential threat of complete water depletion in a city susceptible to both drought and flooding.David Topp is a Queensland Barrister. His previous book Tennyson Breach was published in 2012.

The book presents the recent advances on testing and experimentation in civil engineering, especially in the branches of geotechnics, transportation, hydraulics, and natural resources. It includes advances in physical modelling, monitoring techniques, data acquisition and analysis, and provides an invaluable contribution for the installation of new civil engineering experimental facilities. The first part of the book covers the latest advances in testing and experimentation in key domains of geotechnics: soil mechanics and geotechnical engineering, rock mechanics and rock engineering, and engineering geology. Some of the topics covered include new developments in topographic survey acquisition for applied mapping and in situ geotechnical investigations; laboratory and in situ tests to estimate the relevant parameters needed to model the behaviour of rock masses and land structures; monitoring and inspection techniques designed for offshore wind foundations. The second part of the book highlights the relevance of testing and monitoring in transportation. Full-scale accelerated pavement testing, and instrumentation becomes even more important nowadays when, for sustainability purposes, non-traditional materials are used in road and airfield pavements. Innovation in testing and monitoring pavements and railway tracks is also developed in this part of the book. Intelligent traffic systems are the new traffic management paradigm, and an overview of new solutions is addressed here. Finally, in the third part of the book, trends in the field and laboratory measurements and corresponding data analysis are presented according to the different hydraulic domains addressed in this publication, namely maritime hydraulics, surface water and river hydraulics and urban water. 

This book provides a state-of-the-art review of recent analytical developments on multi-outlets pipe flow hydraulics and alternative hydraulic design concepts. For this purpose, the book presents simple, but sufficiently accurate analytical equations, that can be applied directly without needing any numerical technique to achieve whole hydraulic computations. The analytical procedures explained here give an opportunity for designers to better understand the basic hydraulic principles of multi-outlet pipe flow, and demonstrate their applicability and efficiency to design problems of multi-outlet sub-main lines, covering various design configurations.

This book is designed to give an existing state of knowledge in the field of hydrology, irrigation engineering, and hydraulic structures in a brief manner so that students can use it for their own reference from time to time. Compared to other voluminous books available on the subject, the author has tried to cover the important subject matter in an abridged manner in approximately 320 pages. Besides the full explanation of the theoretical aspects with well-illustrated figures, it gives a number of solved numerical examples. Problems for practice are also given with answers at the end of each chapter.

This book is based on the industry leading short course of the same name hosted by the GIW Industries Hydraulic Laboratory and founded by Dr. Roland Clift and Graeme Addie, who together with Dr. Ken Wilson continued its development and authored the first edition of this textbook. This fourth edition has been extensively updated by the international team of engineers and authors who inherited this legacy and continue its development to the present day. Focusing on the hydraulic design of slurry pipelines, the pumps that power them, and the interactions between pumps and systems, it retains the classroom tested balance of theoretical development and practical engineering which have made it a slurry transport classic. The topics covered are important to slurry system engineers for the optimization of new designs, as well as the operators of existing systems, who may need to calculate and plan for changing conditions from day to day.Updates to the fourth edition include:· Careful formulation of the theoretical concepts, providing greater clarity of slurry flow dynamics, including a new chapter on the principles and characterization of slurry flows.· Expansion of the 4-Component Models for settling slurry pipeline flow and pump solids effect, based on an extensive series of full-sized tests.· An expanded treatment of complex slurries, including a broader discussion of non-Newtonian fluids and their interaction with coarse particles.· A new chapter on test methods, presenting an overview of slurry system instrumentation, moderntechniques for characterizing slurry rheology, and practical advice for planning and executing a slurry test.· An overview of advances in the computational modeling of slurries, including an in-depth parametric study of slurry pump wear and operating cost.The authors highlight methods for achieving energy efficiency, which are crucial to the effective use of scarce resources, given the foundational role of slurry transport systems in the energy intensive industries of mining and dredging. Key concepts are supported with case studies and worked examples.Slurry Transport Using Centrifugal Pumps, fourth edition, is both methodical and in-depth. It is ideal as a teaching tool for classroom or self-directed learning domains, and valuable as a design guide for engineer practitioners at all experience levels.
