Quaternary alluvial fan morphodynamics and basin sedimentation in North Iran PDF Author: Christian Büdel
Publisher: BoD – Books on Demand
ISBN: 3958261140
Category : Science
Languages : en
Pages : 146

Book Description
Availability of water and desiccation of important water reservoirs is a vital challenge in semi-arid to arid climates with growing economy and population. Low quantities of precipitation and high evaporation rates leave the water supply vulnerable to human activity and climatic variations. Endorheic basins of Northern Iran were hydrologically landlocked within geological timescales and thus bear evidence of past variations of water resources in generations of water related landforms, like abandoned lake level shorelines, alluvial fans and stream terraces. Understanding the development of these landforms reveals crucial information about past water reservoirs and landscape history. This study offers a comprehensive approach on understanding the geomorphological development of the landscape throughout Late Pleistocene and Holocene times. It integrates remote sensing and geographic information system analysis, with geomorphological and stratigraphical mapping fieldwork and detailed sedimentological investigations. The work shows the importance of analytical geomorphological mapping for delineating stratigraphic units of the Iranian Quaternary. Thus, several phases of drying and lake level retreat were identified in parallel geoarchives and could be dated to a time span from today to Late Pleistocene. The findings link the fate of the citizens of the ancient city of "Tepe Hissar" to their access to water and to the power of geomorphological processes, which started changing their environment.

Geology and Geomorphology of Alluvial and Fluvial Fans

Geology and Geomorphology of Alluvial and Fluvial Fans PDF Author: D. Ventra
Publisher: Geological Society of London
ISBN: 1786202670
Category : Science
Languages : en
Pages : 351

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.

Modeling and Practice of Erosion and Sediment Transport under Change

Modeling and Practice of Erosion and Sediment Transport under Change PDF Author: Mohamed Meddi
Publisher: MDPI
ISBN: 3039214314
Category : Technology & Engineering
Languages : en
Pages : 212

Book Description
Climate and anthropogenic changes impact the conditions of erosion and sediment transport in rivers. Rainfall variability and, in many places, the increase of rainfall intensity have a direct impact on rainfall erosivity. Increasing changes in demography have led to the acceleration of land cover changes in natural areas, as well as in cultivated areas, and, sometimes, in degraded areas and desertified landscapes. These anthropogenized landscapes are more sensitive to erosion. On the other hand, the increase in the number of dams in watersheds traps a great portion of sediment fluxes, which do not reach the sea in the same amount, nor at the same quality, with consequences on coastal geomorphodynamics. This book is dedicated to studies on sediment fluxes from continental areas to coastal areas, as well as observation, modeling, and impact analysis at different scales from watershed slopes to the outputs of large river basins. This book is concentrated on a number of keywords: “erosion” and “sediment transport”, “model” and “practice”, and “change”. The keywords are briefly discussed with respect to the relevant literature. The contributions in this book address observations and models based on laboratory and field data, allowing researchers to make use of such resources in practice under changing conditions.

Tectonic Geomorphology

Tectonic Geomorphology PDF Author: Douglas W. Burbank
Publisher: John Wiley & Sons
ISBN: 1444345044
Category : Science
Languages : en
Pages : 494

Book Description
Tectonic geomorphology is the study of the interplay between tectonic and surface processes that shape the landscape in regions of active deformation and at time scales ranging from days to millions of years. Over the past decade, recent advances in the quantification of both rates and the physical basis of tectonic and surface processes have underpinned an explosion of new research in the field of tectonic geomorphology. Modern tectonic geomorphology is an exceptionally integrative field that utilizes techniques and data derived from studies of geomorphology, seismology, geochronology, structure, geodesy, stratigraphy, meteorology and Quaternary science. While integrating new insights and highlighting controversies from the ten years of research since the 1st edition, this 2nd edition of Tectonic Geomorphology reviews the fundamentals of the subject, including the nature of faulting and folding, the creation and use of geomorphic markers for tracing deformation, chronological techniques that are used to date events and quantify rates, geodetic techniques for defining recent deformation, and paleoseismologic approaches to calibrate past deformation. Overall, this book focuses on the current understanding of the dynamic interplay between surface processes and active tectonics. As it ranges from the timescales of individual earthquakes to the growth and decay of mountain belts, this book provides a timely synthesis of modern research for upper-level undergraduate and graduate earth science students and for practicing geologists.

The Soils of Iran

The Soils of Iran PDF Author: Mohammad Hassan Roozitalab
Publisher: Springer
ISBN: 3319690485
Category : Nature
Languages : en
Pages : 257

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.
