Estuaries are natural highly dynamic and rapidly changing systems, comprising a complex combination of physical processes on many different time- and space- scales. The research conducted a systematic study on the topic of fine sediment physical processes in a meso-tidal convergent alluvial estuary. By means of multi-approaches (field survey, laboratory experiment and numerical modeling) and from multi-angles (data-driven analysis and process-based modeling) we highlight that multiscale (including micro- and macro- scale) physical processes jointly characterize the current and sediment regime in a fine sediment estuarine system. The study presented in this book investigates micro- and macro- scale physical processes of a large-scale fine sediment estuarine system with a moderate tidal range as well as a highly seasonal-varying freshwater inflow. Based on a series of measured, experimented and modelled data, the research highlights that (i) along-channel fresh-salt gradient near an estuarine turbidity maximum zone is a key parameter controlling local density stratification and sedimentation in the channel; (ii) the salinity-induced baroclinic pressure gradient forces are a major factor impacting internal velocity and suspended sediment concentration (SSC) structures; (iii) vertical profiles of current, salinity and SSC within a river plume are dependent on a correct prediction of the development of turbulence; (iv) both suspended particulate matter availability and local residual flow regime are of critical importance for trapping probability of sediment and the occurrence of fluid mud; (v) river discharge impacts the horizontal and vertical distribution of residual current; (vi) seasonally varying wind effect alters the residual currents near the riverine limit; (vii) seasonally varied mean sea level and wind climate jointly shape the saltwater intrusion length near the estuarine front.

Natural ecosystems are heavily dependent on water, as it is essential to the development of life. The ecology and landscape play an important role in the quality and availability of water. It is no coincidence that exceptional hydrological phenomena are found in protected areas. Such is the case with, for example, the geothermic occurrences (principally, geysers) in America's Yellowstone National Park , the oldest park in the world. The Ramsar wetlands (where the ecosystem's dependency on water is strongly evident), The Iguacu Falls (on the border of Argentina and Brazil), or the Zapata Swamp (the largest of its kind on the Caribbean island of Cuba) further exemplify this point. However, in many cases, the conservation strategies for hydraulic resources in protected areas are ignored, or simply deprived of the attention they require. There are many types of suitable management strategies for planning and protecting our valuable treasures. Hydraulic resource management in protected areas is something that must not be separated from these conservation measures. The first Symposium for the Management of Hydraulic Resources in Protected Areas was intended to be a framework of communication about experiences with water resource management in protected areas. Advances in research and possible solutions to the problems within these areas were discussed. The contributions in this proceedings volume are grouped under seven main themes: Purification and reuse of wastewater in rural communities; Impact of public use on water resources; Vulnerability and risks associated with aquifers, Design and management water resources in protected areas; Research and monitoring of water resources in protected areas; Water and its importance as a source of renewable energy in protected spaces; and Geodiversity and conservation of areas with hydraulic heritage.

Stakeholders' lack of awareness, involvement and participation in the planning and management of water resources and flood risk often creates problems in the acceptance and implementation of proposed measures. Interactions among stakeholders and decision makers build awareness, trust, enhance cooperation and negotiation for best possible measures. The main challenge in stakeholder participation is maintaining the participatory process. Stakeholders' spatial distribution, limitation of financial resources and diverse stakeholders' interest (even opposed) are some of the hindrances in maintaining the participatory process. Addressing these challenges and hindrances, this research developed and implemented three frameworks for developing "Networked Environments for Stakeholder Participation" (NESPs). Networked environments are web-based computer-aided or mobile environments for remote virtual interaction between participating entities such as stakeholders. NESPs are envisioned to enable stakeholder participation by providing sharing of information, planning, negotiating and decision support. NESPs were implemented in five real case studies (1) Lakes of Noord-Brabant, The Netherlands, (2) Danube river (Braila-Isaccea section), Romania, (3) Somes Mare catchment, Romania, (4) Cranbrook catchment, London and (5) Alster catchment, Hamburg, Germany. The overall results of the research show that networked environments can address the challenges and hindrances in stakeholder participation and enhance participation in water resources and flood management.

Floods are one of the most common and widely distributed natural risks to life and property worldwide. There is a need to identify the risk of flooding in flood prone areas to support decisions for flood management from high level planning proposals to detailed design. An important part of modern flood risk management is to assess vulnerability to floods. This assessment can be done only by using a parametric approach. Worldwide there is a need to enhance our understanding of vulnerability and to also develop methodologies and tools to assess vulnerability. One of the most important goals of assessing flood vulnerability is to create a readily understandable link between the theoretical concepts of flood vulnerability and the day-to-day decision-making process and to encapsulate this link in an easily accessible tool. The present book portrays a holistic parametric approach to be used in flood vulnerability assessment and this way to facilitate the consideration of system impacts in water resources decision-making. The approach was verified in practical applications on different spatial scales and comparison with deterministic approaches. The use of flood vulnerability approach can produce helpful understanding into vulnerability and capacities for using it in planning and implementing projects.

The research presented in this work qualitatively investigates the morphodynamic response of a large tidal inlet/basin system to future relative sea level rise (RSLR) using the state-of-the-art Delft3D numerical model. Understanding the potential impacts of RSLR on these systems is a prerequisite for their sustainable management due to their rich bio-diversity and the increase in economic activities and local communities in recent decades. The adopted approach used a highly schematised model domain analogous to the Ameland inlet in the Dutch Wadden Sea. Model simulations were undertaken applying tidal and wave boundary forcings with three IPCC projected RSLR scenarios (no RSLR, low RSLR and high RSLR). Predicted inlet evolution indicated a channel/shoal pattern typically observed at the Ameland inlet. RSLR enhances the existing flood-dominance of the system leading to erosion on the ebb-tidal delta and accretion in the basin. Under the no RSLR case, resulting bed evolution of the process-based model (Delft3D) tends to agree with empirical-equilibrium relations of the ASMITA model. Application of the low RSLR scenario resulted in quite stable tidal flat evolution. Model simulations with the high RSLR scenario indicated disappearing the tidal flats over time and turning the system into a lagoon. Applying nourishment hardly compensated the RSLR induced sediment demand of tidal flat evolution.

Coastal reservoirs are viewed in many regions of the world as an emerging concept of storing fresh water when the river basin is in flood. Similar reservoirs (or impoundments) can be used to generate tidal renewable energy and/or provide the catalysis for urban regeneration. Constructed near the coast in natural river basins, these reservoirs have a smaller environmental footprint and are less obstructive than inland dams. Written by an international group of Civil, Environmental, and Geotechnical Engineers, Sustainable Water Resource Development using Coastal Reservoirs discusses the latest research and breakthroughs in their use, while offering expert advice into their sustainable design and construction. The perfect reference for researchers exploring the feasibility of this emerging technology or experienced professionals who wish to implement this technology as a water scarcity solution or a tidal renewable energy source or for urban regeneration, Sustainable Water Resource Development using Coastal Reservoirs provides an expert resource to the design, construction and use of coastal reservoirs. The reference begins with a brief but readable examination of water quantity, quality design and geotechnical considerations. The book includes international case studies to clearly illustrate the various uses, design, planning, construction, and operation methods. These case studies include projects such as: Afsluitdijk in the IJsselmeer, (Netherlands), Zuiderzee (Netherlands), Thanneermukkom Bund (India), Sihwa (South Korea), Saemangeum, (South Korea), Chenhang (China), Plover Cove (China), and Marina Barrage (Singapore).

Expanding a port, deepening a navigation channel or creating new land for development, introduces changes to our physical, social, economic and political environment. Changes may result from events during the construction process, or relate to the nature of the completed structure. Changes can be positive or negative, short-term or long-term, and may affect the immediate vicinity of the project or a larger geographical area. Predicting and assessing all possible effects of a planned dredging activity in a scientifically-sound and reliable manner is essential, so that appropriate control measures can be taken to avoid or mitigate unwelcome impacts. This book provides guidance for a complete holistic environmental evaluation procedure and for the design and implementation of environmental control measures. The book is of particular interest to engineers, government agencies and port authorities, as well as civil engineering consultants and contractors involved in planning and designing dredging, maritime infrastructure and fluvial projects.

Humanity is deeply committed to living along the world's shores, but a catastrophic storm like Sandy - which took hundreds of lives and caused many billions of dollars in damages - shines a bright light at how costly and vulnerable life on a shoreline can be. Taking Chances offers a wide-ranging exploration of the diverse challenges of Sandy and asks if this massive event will really change how coastal living and development is managed. Bringing together leading researchers - including biologists, urban planners, utilities experts, and climatologists, among others - Taking Chances illuminates reactions to the dangers revealed by Sandy. Focusing on New Jersey, New York, and other hard-hit areas, the contributors explore whether Hurricane Sandy has indeed transformed our perceptions of coastal hazards, if we have made radically new plans in response to Sandy, and what we think should be done over the long run to improve coastal resilience. Surprisingly, one essay notes that while a large majority of New Jerseyans identified Sandy with climate change and favored carefully assessing the likelihood of damage from future storms before rebuilding the Shore, their political leaders quickly poured millions into reconstruction. Indeed, much here is disquieting. One contributor points out that investors scared off from further investments on the shore are quickly replaced by new investors, sustaining or increasing the overall human exposure to risk. Likewise, a study of the Gowanus Canal area of Brooklyn shows that, even after Sandy swamped the area with toxic flood waters, plans to convert abandoned industrial lots around the canal into high-density condominiums went on undeterred. By contrast, utilities, emergency officials, and others who routinely make long-term plans have changed operations in response to the storm, and provide examples of adaptation in the face of climate change. Will Sandy be a tipping point in coastal policy debates - or simply dismissed as a once-in-a-century anomaly? This thought-provoking collection of essays in Taking Chances makes an important contribution to this debate.
