Application of the Systems Approach to the Management of Complex Water Systems
No full textDuring the past five decades, we have witnessed a tremendous evolution in water resource system management. Three characteristics of this evolution are of particular note: First, the application of the systems approach to complex water management problems has been established as one of the most important advances in the field of water resource management. Second, the past five decades have brought a remarkable transformation of attitude in the water resource management community towards environmental concerns and action to address these concerns. Third, applying the principles of sustainability to water resource decision-making requires major changes in the objectives on which decisions are based, and an understanding of the complicated inter-relationships between existing ecological, economic, and social factors. The Special Issue includes 15 contributions that offer insights into contemporary problems, approaches, and issues related to the management of complex water resources systems. It will be presumptuous to say that these 15 contributions characterize the success or failure of the systems approach to support water resources decision-making. However, these contributions offer interesting lessons from current experiences and highlight possible future work
Lowering Risk by Increasing Resilience
No full textThe reprint identifies key concerns and significant challenges of the future as currently perceived by researchers, industry, policymakers, and other flood management stakeholders. The main themes addressed include: science and technology for flood risk management; handling data and information for flood risk management; flood disaster prevention, mitigation, and adaptation; flood preparedness, response, and recovery; flood decision-making, policy, and governance; and flood resilience
Development of planning tools for the ecologically sound operation of reservoirs
No full textWithin the state of Northrhine Westphalia, Germany, 72 reservoirs store and provide water for manifold uses; many of them are combined in multipurpose systems. Often their management and operation still follow rules originally developed during their planning phase or shortly thereafter. After decades of operation it has become evident that the rule curves used have caused noticeable ecological changes in the downstream reaches of the reservoirs. The stage agency for environment has initiated the development of planning instruments to enable reservoir operators to improve release rules by using dynamic short-term and long-term control policies. The concept is based on deterministic real-time modeling using daily or hourly time-steps according to stream flow intensities. For the daily operation heuristic rules are being developed based on long-term historic records, while flood control is based on actually measured and forecast inflows. Flood waves might be propagated through the reservoirs to cause high frequency, but low intensity floods to reactivate downstream flood plains as part of the aquatic/amphibious environment

Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
