Og stormfloden kom En 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.

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.

A natural disaster cannot be anticipated in any kind of form by humankind. These may occur in the form of floods, seismic, volcanos, and hurricanes. The menace of these occurrences cannot be stopped at will, but a robust framework can be created by applying the concept of resilience. Resilience means the strength of a community to resist the effect of any hazard and bounces back to that community's desired level of performance after the occurrence of the risk. Resilience is defined as a system's ability to withstand and recover from the effects due to natural or human-made hazards. In any community, the meaning of resilience can be taken as the time taken by the socio-physical infrastructure to bounce back to its original or functional state. The concept of resilience is well established in various domains, such as ecology, finance, engineering, and medical science. Infrastructure resilience mainly depends on four key factors for a particular, where systems' robustness is the ability to resist the effects of a disaster, redundancy is the availability of alternative resources ensuring operational requirements during/after a disaster, rapidity is the time taken to bounce back to its original/desirable position and resourcefulness is the availability of resources for recovery.Any system's performance loss and recovery profile are typically uncertain in nature, primarily due to the inherent uncertainty in natural hazards (related to system damage) and the time variation in the restoration process due to resource availability. Performance loss mainly depends on both robustness and redundancy. In most cases, recovery is modelled as a linear or stepped profile for critical infrastructure systems instead of nonlinear. The recovery profile mainly depends on the type of infrastructure system under consideration and resource availability. For instance, a stepped recovery pattern is typically followed in restoring road and bridge systems.

A dam refers to a part of infrastructure system that comprises different structures designed to store, collect and manage water. There are different types of dams, such as buttress dams, gravity dams, embankment dams and arch dams. The reservoirs formed by dams not only prevent floods, but they also provide water for multiple purposes, including industrial use, irrigation, human consumption and aquaculture. Dam engineering is a field of engineering that deals with the problems associated with the building, planning and maintenance of dams. The development and building of dams has benefited the human civilization, by providing a supply of power and fresh water, as well as shielding it from calamities such as floods and storms. This book is a valuable compilation of topics, ranging from the basic to the most complex advancements in the field of dam engineering. It strives to provide a fair idea about this discipline and to help develop a better understanding of the latest advances within this field.
