Catchment2coast. Catchment2Coast was an interdisciplinary research and modeling project that aimed to improve understanding of the linkages between coastal ecosystems and the adjacent river catchments. The project involved nine partner organizations from three European and three southern African countries, including Mozambique, where the project was conducted. Catchment2Coast has tackled a problem which is at the interface of many different domains: between river and the sea, between bay and ocean, between water and soil, but also between ecology and economy. It used a variety of tools and methods, ranging from continuous hydrodynamic monitoring and biochemistry flux measurements to remote sensing and mathematical modeling techniques, but perhaps even more important was the integration of disciplines that took place during the project, which consisted of experts from different countries both from Europe and Southern Africa. The knowledge gained through this research provides a sound basis for the setting of environmental flow requirements for the Maputo, Incomati and similar river systems in sub-Saharan Africa. And what is more, it may serve as an example and stimulus for continued cooperation between experts from different disciplinary and cultural backgrounds.

The Role Of Bathymetry Wave Obliquity And Coastal Curvature In Dune Erosion Prediction. Coastal areas have traditionally been an attractive place for people to live, but if these areas are low-lying, they are also prone to flooding. In the Netherlands, half of the population lives in coastal areas below mean sea level. Dunes are the primary sea defense along most of the Dutch coastline, and the envisaged protection level of this densely populated and economically valuable area is one of the highest in the world. Since extreme design storm events have not been observed in recent history, the design, evaluation and maintenance of flood defense systems relies on models and data extrapolation. This book is about the reduction of uncertainty in dune erosion prediction, and the improvement of dune safety assessment, particularly for complex dune coasts. With reference to the Dutch experience, it describes the use of state-of-the-art, process-based models for studying the influence of cross-shore bathymetry, wave obliquity and coastline curvature on dune erosion. A reduction in the uncertainty of dune erosion prediction is envisaged by deploying a more comprehensive modeling approach and a tailored probabilistic approach. In addition, the use of a Bayesian Network model overcomes the limitations of the probabilistic methods, and allows model, field and laboratory data to be combined with expert opinion to estimate dune erosion rate. The book stresses the importance of wave obliquity and coastal curvature for the assessment of dune safety against flooding and will be of interest to all those involved in flood prevention in coastal areas.

Making Sense Of Virtual Risks. Along with the rise of digital games over the past decades came an increased interest in using games for other purposes than entertainment. Although a few successes are known, much research seems to suggest little evidence for games advantages. Existing literature claims that more comprehensive, rigorous, and innovative studies are needed to investigate the effective design and use of games.To contribute to this emerging field, the author investigated the case of Levee Patroller. The target audience of this game, levee patrollers, are considered the eyes and ears of the Dutch water authorities. They inspect levees and report any risks

Bridging Boundaries. Bridging Boundaries: Making Scale Choices in Multi-Actor Policy Analysis on Water Management synthesizes different perspectives on scale choices (spatial boundary setting, temporal boundary setting and selection of level of aggregation) in policy analysis. Scale choices influence the content of a study (the problems on the agenda, the options found and the impacts addressed) and the process (actors involved, their dedication and criticalness). Scale choices are not politically neutral: they may have advantages or disadvantages for certain actors by putting their urgent problems and their preferred options on the agenda, while they may hide or stress positive or negative impacts of options. Yet, little is known about the specific effects of scale choices and how they are made in practice. In this research, the making of scale choices is studied in two cases in practice: the Long Term Vision Study of the Scheldt Estuary and the Water Shortage Study of the Netherlands. Scale choices appear to be an important framing instrument that can be used by the policy analyst.

Dune Erosion During Storm Surges. Because large parts of The Netherlands lie below sea level and are largely protected from flooding by a narrow strip of sandy beaches and dunes, optimal management of this coastal strip is of vital importance. This work extends the existing knowledge of dune erosion during storm surges as it occurs along the Dutch coast. Among the areas discussed are: a large scale erosion experiment designed to improve insight into near dune hydrodynamics, sediment transport and interaction between dune face and swash zone; detailed modeling to study dune erosion physics, validated against measurements, and a morphodynamic dune erosion model applied in a variety of dune erosion conditions. This publication represents a valuable contribution to an improved understanding of dune erosion, an increasingly important area of study with regard to climate change and rising sea levels.
