Book Description

This book presents a complete set of studies of alluvial fan sediments in southern Iran from the point of view of sedimentology, sedimentary geochemistry, tectonics, economic geology, groundwater, geomorphology, hazards and telemetry. In addition, the book focuses on advanced topics and theory, which practically serves as a model for the study of this type of sediment around the world. Alluvial fans are an important and fundamental factor in many sciences such as geology, environmental science, natural hazards, groundwater science, agriculture and many other related sciences. Lack of accurate knowledge of their constituent sediments has always been an important problem for experts in many science disciplines. From the economic point of view, the identification of alluvial fan deposits is of particular importance. For example, alluvial deposits are the centre of groundwater accumulation, and most groundwater reservoirs within the sedimentary basin are fed by water from alluvial deposits. Most of the gold production in South Africa has been formed as placer deposits in ancient alluvial fans. In addition, a large amount of uranium placer deposits is extracted from old alluvial fans in sedimentary basins in South Africa. This book serves as an ideal guide for experts in earth and environmental sciences and hydrology.

Book Description

Alluvial fans are important sedimentary environments. They trap sediment delivered from mountain source areas, and exert an important control on the delivery of sediment to downstream environments, to axial drainages and to sedimentary basins. They preserve a sensitive record of environmental change within the mountain source areas. Alluvial fan geomorphology and sedimentology reflect not only drainage basin size and geology, but change in response to tectonic, climatic and base-level controls. One of the challenges facing alluvial fan research is to resolve how these gross controls are reflected in alluvial fan dynamics and to apply the results of studies of modern fan processes and Quaternary fans to the understanding of sedimentary sequences in the rock record. This volume includes papers based on up-to-date research, and focuses on three themes: alluvial fan processes, dynamics of Quaternary alluvial fans and fan sedimentary sequences. Linking the papers is an emphasis on the controls of fan geomorphology, sedimentology and dynamics. This provides a basis for integration between geomorphological and sedimentological approaches, and an understanding how fluvial systems respond to tectonic, climatic and base-level changes.

Book Description

Alluvial and fluvial fans are the most widespread depositional landform bordering the margins of highland regions and actively subsiding continental basins, across a broad spectrum of tectonic and climatic settings. They are significant to the local morphodynamics of mountain regions and also to the evolution of sediment-routing systems, affecting the propagation and preservation of stratigraphic signals of environmental change over vast areas. The volume presents case studies discussing the geology and geomorphology of alluvial and fluvial fans from both active systems and ancient ones preserved in the stratigraphic record. It brings together case studies from a range of continents, climatic and tectonic settings, some introducing innovative monitoring and analysis techniques, and it provides an overview of current debates in the field. This volume will be of particular interest to geologists, geomorphologists, sedimentologists and the general reader with an interest in Earth science.

Book Description

This unique book addresses Iran’s extremely rich soil diversity and resources, which have developed under various climatic conditions ranging from dry to humid conditions. Featuring contributions by a group of respected experts on Iranian soils and agriculture, it provides comprehensive information on the management approaches needed for sustainable soil utilization and conservation under such conditions, and the attendant challenges. As such, it offers a valuable resource for anyone interested in soils and agriculture in Iran, but also in other Middle East and North African countries with similar climatic conditions. The book contains 14 chapters which illustrate the long history of indigenous knowledge and soil research, climate, geology and geomorphology, vegetation cover, soil forming factors and processes, major soils, properties and their classification. Furthermore, it presents past climate change and paleosols, agroecological zones, soil fertility, soil biology and biotechnology, human induced land degradation and “soil management in space and time”. In the end, major challenges facing the soil resources of the country are defined and recommendations are made to face the future challenges.

Book Description

This book offers a unique and highly illustrated overview of the desert geomorphology of Iran. It describes the different landscapes and landforms of desert areas such as ergs and badlands offering a comprehensive insight into typical fluvial and eolian forms such as playas, alluvial fans, yardangs, salt domes, dunes, hoodoos and many more. The monograph elaborates the interaction of humans with the landscapes and discusses ongoing developments in geotourism, natural heritage sites as well as the potential for geoparks. Desert Landscapes and Landforms of Iran contains many photographs, satellite images, high-resolution aerial photos, maps, charts and tables which build a nice framework for the assessment of the different geomorphological features. It constitutes a comprehensive introduction for researchers and students of many disciplines in the fields of geography, geosciences, tourism and leisure studies, environmental sciences and landscape planning interested in typical physical characteristics of desert landscapes.

Book Description

Qanats are ubiquitous, yet unseen, and a clever way to create streams where none exist in nature. For 3,000 years, they have made life possible in impossible places and still sustain life and livelihoods in many countries today. After 30 years of field research, Dale Lightfoot provides the first comprehensive study of the qanat and sheds new light on their unique locations and distribution, their origins and history, their ecology, current status and use. Qanats are remarkably engineered underground aqueducts, using gravity to bring water to villages and towns where reliable flowing surface water is scarce or absent. Although an ancient technology, more than 46,000 of them still flow around the world today, with their sustainable nature making them a focus of renewed interest. Richly illustrated with images and a series of original maps, this is the most complete record to date of the locations and distribution of qanats worldwide, including examples from the Middle East, North Africa, Europe, Central Asia, China, India, Mexico and South America.

Book Description

Alluvial fans are gently sloping, fan-shaped landforms common at the base of mountain ranges in arid and semiarid regions such as the American West. Floods on alluvial fans, although characterized by relatively shallow depths, strike with little if any warning, can travel at extremely high velocities, and can carry a tremendous amount of sediment and debris. Such flooding presents unique problems to federal and state planners in terms of quantifying flood hazards, predicting the magnitude at which those hazards can be expected at a particular location, and devising reliable mitigation strategies. Alluvial Fan Flooding attempts to improve our capability to determine whether areas are subject to alluvial fan flooding and provides a practical perspective on how to make such a determination. The book presents criteria for determining whether an area is subject to flooding and provides examples of applying the definition and criteria to real situations in Arizona, California, New Mexico, Utah, and elsewhere. The volume also contains recommendations for the Federal Emergency Management Agency, which is primarily responsible for floodplain mapping, and for state and local decisionmakers involved in flood hazard reduction.
