Monitoring, Simulation, Prevention and Remediation of Dense Debris Flows II
This book contains papers presented at Second International Conference on Debris Flow including all aspects of Debris Flow Monitoring, Modelling, Hazard Assessment, Mitigation Measures, Case Studies and Extreme Events, Erosion, Slope Instability and Sediment Transport, held in the New Forest, UK in 2008 and organised by the Wessex Institute of Technology, with the co-sponsorship of EurAgEng (European Society of Agricultural Engineers) and CIGR (International Commission of Agricultural Engineering). Due to the increased frequency with which debris and hyper-concentrated flows occur and the impact they have on both the environment and human life, in recent years these extreme events and relate...
Innovative Biosystems Engineering for Sustainable Agriculture, Forestry and Food Production
This book gathers the latest advances, innovations, and applications in the field of innovative biosystems engineering for sustainable agriculture, forestry and food production. Focusing on the challenges of implementing sustainability in various contexts in the fields of biosystems engineering, it shows how the research has addressed the sustainable use of renewable and non-renewable resources. It also presents possible solutions to help achieve sustainable production. The Mid-Term Conference of the Italian Association of Agricultural Engineering (AIIA) is part of a series of conferences, seminars and meetings that the AIIA organizes, together with other public and private stakeholders, to promote the creation and dissemination of new knowledge in the sector. The contributions included in the book were selected by means of a rigorous peer-review process, and offer an extensive and multidisciplinary overview of interesting solutions in the field of innovative biosystems engineering for sustainable agriculture.
AIIA 2022: Biosystems Engineering Towards the Green Deal
This volume gathers the latest advances, innovations, and applications in the field of biosystems engineering, as presented at the 12th Conference of the Italian Association of Agricultural Engineering (AIIA), held in Palermo, Italy, on September 19-22, 2022. Focusing on the challenges of improving the resilience of agriculture, forestry and food systems in the post-Covid era, it shows how the research has addressed the following topics: Monitoring and modelling hydraulic and hydrological processes in agriculture and forestry systems; Challenges in stream rehabilitation and soil conservation strategies; Sustainable water resource management under climate change scenarios; Planning safe, heal...
Engineering Geology for Society and Territory - Volume 3
This book is one out of 8 IAEG XII Congress volumes and deals with river basins, which are the focus of many hydraulic engineering and hydrogeological studies worldwide. Such studies examine river systems as both a resource of the fluvial environment, and also explore river-related hazards and risks. The contributions of researchers from different disciplines focus on: surface-groundwater exchanges, stream flow, stream erosion, river morphology and management, sediment transport regimes, debris flows, evaluation of water resources, dam operation and hydropower generation, flood risks and flood control, stream pollution and water quality management. The contributions include case studies for ...
Grassland Biodiversity
"Genetic diversity and species diversity are both crucial for ecosystem stability. Analysis of plant diversity aims to understand the organization and the variability of biological populations within ecosystems. This book provides a review on chemotaxonomical criteria helping to understand complex structures of plant diversity. It focuses particularly on the chemotaxonomic usefulness of phenolic compounds in analysis of chemical polymorphisms at different taxonomic levels. The relationship between grazing pressure and grassland vegetation is also examined, using drastically improved information technology such as remote sensing, Geographic Information System (GIS) and Ground Positioning Systems (GPS). Furthermore, an overview of the unique ecosystem of the South Brazilian Campos grasslands are given. The role of disturbance in maintaining Campos biodiversity and dynamics, and the importance of its conservation, is looked at as well. Other chapters in this book discuss the relationship between management and vegetation, and also suggest ways to conserve the species diversity of both plants and butterflies in semi-natural grassland."--Publisher's description.
Biodiversity Hotspots
Current loss of biodiversity places a premium on the task of recognising and formulating proposals on potential areas for biological conservation based on scientific criteria; among these tasks, identification of hotspots has a relevant role on conservation of biodiversity. In this book, the authors discuss the application of different biogeographic methods to identify plant biodiversity hotspots. The areas recognised as such have a relevant role in plant biodiversity and are important in conservation due to their climatic conditions, the historical factors that have been involved in their evolution, and the restricted distribution of some plant taxa that inhabit them. Furthermore, the consequences of deforestation on biodiversity are substantial and widely recognised. This book predicts future land-use change, generates ecological niches of large mammals and assesses wildlife concentrations and their hotspots in different areas of the world. The evolution of the forest fragmentation in the Brazilian Atlantic forest, the present situation of its remnants, and the main strategies, conflicts and potentials for conservation are evaluated as well.
Estuaries
Estuaries are productive ecosystems of high ecological value. They are important habitats for various species and those of highest value are protected by national and international conventions. This book highlights possible pollution impacts in a protected estuarine ecosystem, Amvrakikos Gulf, considered as one of the most important wetlands in Greece. In addition, the Changjiang (Yangtze) River is known to contribute significantly to the ecosystems of the Changjiang River estuary and adjacent waters. In this book, some long-term data of freshwater discharge, sediment load, nutrient concentrations and compositions in the river and estuary waters are presented, as well as the long-term respon...
Check Dams, Morphological Adjustments and Erosion Control in Torrential Streams
Check dams are a potentially effective instrument for planning of hydrological risks and soil conservation. Cross structure sequences have been used in numerous areas in the world to control flooding, recharge aquifers and stabilise mountain streams, gullies and high-gradient ephemeral channels. Nevertheless, it is little known of the effectiveness of check dams and their morphological effects. This book is an attempt to compile different based-field and laboratory research works in torrential head water areas. Bed stability variations will be investigated according to check dams types, bedrock control, bed slope, channel roughness, lateral sediment input, and highly variable sediment transport capacity. Though the main purpose of check dams is to stabilise the channel bed and diminish the boundary sheer stress reaching a minor longitudinal slope, they can reduce the volume of channel-stored material favouring local scour processes downstream and occasionally destabilise the hill slopes upstream.
