Book excerpt: Academic Paper from the year 2021 in the subject Geography / Earth Science - Geology, Mineralogy, Soil Science, grade: 10, National & Kapodistrian University of Athens, language: English, abstract: This paper deals with the sedimentary environment of the Indus River in Pakistan and the question of how anthropogenic activities change its sediments. Indus River is the longest river in the Asian territory, originated from Tibet Mountain northwest of Pakistan. Routed from the northern part of Gilgit and flowing to word plan area passed through different provinces and flow with sedimentary flux connected with many small and large tributaries tectonically the birth of the rive due to collision of Indian and Eurasian plate that are called Indus suture Plains zone (ISPZ). The main geology composed of igneous and metamorphic rock. The river passed in the various climatic zone with different regions mostly climate is subtropics arid and sub arid to subequatorial. The northern area mostly coved by monsoon system variation of seasonality takes place in the month of May to Oct high flow with increase sedimentary flux special in monsoon time. Anthropogenic activities locally and widely in terms of construction of dams water canals for irrigation purposes, mining exploration, and industries and factories all flux flow in different tributaries impacted on physical and chemical behaviors of the sediments. The primary impact of anthropogenic processes is the reworking of weathered soil smectite which is an indicator of chemical weathering and which increases in the offshore record after around 5000 years ago. This material indicates greater transport of stronger chemically weathered material and some of this may be caused by the erosion of old soils broken up by agriculture, although we also see evidence for the incision of the big rivers into the floodplain which is also driving reworking of this type of material so the signal may be a combination of the two. The dramatic change in shape and size of the sediments by colliding each other during the high charge river.

Book excerpt: Academic Paper from the year 2023 in the subject Geography / Earth Science - Physical Geography, Geomorphology, Environmental Studies, grade: 3.3, Federal Urdu University (University of Karachi), course: Environmental Science, language: English, abstract: This study came at a critical time in the area. The feeble seasonal monsoon of 2009 caused a deficiency across the Pakistan. This comes after many rural households were already in dire straits facing high fertilizer charges and the impact of increasing world food prices. To aggravate the matters, the calamitous monsoon floods of 2010 overblown more than 22 million people, their homelands, structure and harvests. It has been estimated that this single flood caused around US$10 billion in damage, about partial of which was due to fatalities in the agricultural division. Introduction: The Indus Basin has a long and lively history of growth and alteration in irrigation. The settlements of the Harappan evolution in the Indus Valley date back five millennia. During the monsoon season, traces of flood channels remain that cut through the floodplains and allowed the inundation of agricultural fuel, food and minor crops within the riparian corridor. One of the largest dams, the so-called Gabarbands, dam water in torrents and branch catchment areas. Urban toilets and manure systems which aided cities such as Mohenjo-Daro in the Pakistan, Sindh’s lower Indus River section. such smaller cities and were discovered in the 2nd millennium BC. Abandoned due to overflowing of river, salinization, and changes in riverbeds. In a large drainage basin east central Indus valley, the Ghaggar-Hakra river canal changed development during the changes due to river in Harappan era, resulting in the desertion of hundreds of settlements. Such past events raise inquiries about continual sustainability in the setting of lively hydroclimatic unpredictability. Pakistan gets most of its water from monsoon runoff, aquifers and the headwaters of glaciers and snowfields from the rivers of the Indus Basin. In the Hindu Kush-Karakorum Mountain region areas of the Himalayas, 50 to 80 percent of the average Indus flow is due to snow and glacial melt, with the remainder due to monsoonal rains on the plains. Climate transformation may result in increased unpredictability in the supply and effectiveness of snowfall, as well as variations in snow and ice melt, which would affect water resource managing in the basin.

This book was released on 2023-10-17 with total page 441 pages. Available in PDF, EPUB and Kindle. Book excerpt: This edited book provides a platform for knowledge sharing in all areas related to the rivers, sediment and hydrological extremes. It explains the hypothesis that river flow and sediment transport are intimately linked to erosion, scour and sediment deposition. Sediment transport, erosion and deposition are driven by local base-level changes and are highly variable in space and time. These concepts have serious implication for understanding the recent development of the River, Sediment and Hydrological Extremes. The natural hazards posed by hydrologic events and river systems depend on the uncertainty of hydrological events. This ability is affected by change in climatic conditions. Climate change studies have revealed that the frequency of extreme weather phenomena with increasing damage to human assets has gradually grown worldwide. As a consequence, rainfall events concentrated in time and space are expected to lead to serious local flooding and sediment transport in many parts of the world. Floods are remarkable hydro-meteorological phenomena and forceful agents of geomorphic evolution in most physical geographical belts and, from the viewpoint of human society, among the most important environmental hazards. According to the Indian Environment Agency, floods rank as number one on the list of natural disasters in India over the past decade. This book is an attempt to fill the gap in literature and bring forth evidence based latest research about precise estimation of erosion and scour, which is essential to reduce the hazards. The book explains that lack of preparedness and appropriate adaptation strategy makes people more risk-prone. It highlights the vulnerability in South Asia region about the impacts of flood, sediments, and river hazards because a large portion of its population depends on sensitive sectors like agriculture and forestry for livelihoods and several other reasons. The book is relevant for academician, researchers and students of disaster management, hydrology and ecology.

Download or read book Climate ChangeImpact on Coastal Habitation written by Doeke Eisma and published by CRC Press. This book was released on 2021-04-14 with total page 271 pages. Available in PDF, EPUB and Kindle. Book excerpt: Temperature and precipitation increase and decrease because of natural causes. However, anthropogenic changes, such as an enhanced greenhouse effect, may result in alterations in the regional climate and in relative sea level. Serious changes in climate and sea level-with adverse effects particularly along low-lying coasts-would affect millions of people. Climate Change takes an in-depth, worldwide look at coastal habitation with respect to these natural and anthropogenic changes. No universally applicable coastal model can be used to describe climatic changes. This unique book provides individual discussions of beaches and barrier islands, cliffs, deltas, tidal flats and wetlands, reefs, and atolls. The impact of climatic change on coastal ecology and agriculture is investigated, and human responses to the effects of climatic change along the world's coasts are included.

Download or read book Geomorphology in the Anthropocene written by Andrew S. Goudie and published by Cambridge University Press. This book was released on 2016-10-10 with total page 335 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Anthropocene is a major new concept in the Earth sciences and this book examines the effects on geomorphology within this period. Drawing examples from many different global environments, this comprehensive volume demonstrates that human impact on landforms and land-forming processes is profound, due to various driving forces, including: use of fire; extinction of fauna; development of agriculture, urbanisation, and globalisation; and new methods of harnessing energy. The book explores the ways in which future climate change due to anthropogenic causes may further magnify effects on geomorphology, with respect to future hazards such as floods and landslides, the state of the cryosphere, and sea level. The book concludes with a consideration of the ways in which landforms are now being managed and protected. Covering all major aspects of geomorphology, this book is ideal for undergraduate and graduate students studying geomorphology, environmental science and physical geography, and for all researchers of geomorphology.

Available in PDF, EPUB and Kindle. Book excerpt: This study, Indus basin of Pakistan: the impacts of climate risks on water and agriculture was undertaken at a pivotal time in the region. The weak summer monsoon in 2009 created drought conditions throughout the country. This followed an already tenuous situation for many rural households faced with high fuel and fertilizer costs and the impacts of rising global food prices. Then catastrophic monsoon flooding in 2010 affected over 20 million people, devastating their housing, infrastructure, and crops. Damages from this single flood event were estimated at US dollar 10 billion, half of which were losses in the agriculture sector. Notwithstanding the debate as to whether these observed extremes are evidence of climate change, an investigation is needed regarding the extent to which the country is resilient to these shocks. It is thus timely, if not critical, to focus on climate risks for water, agriculture, and food security in the Indus basin of Pakistan.

Download or read book Modelling of Harbour and Coastal Structures written by Theophanis V Karambas and published by Mdpi AG. This book was released on 2021-11-26 with total page 342 pages. Available in PDF, EPUB and Kindle. Book excerpt: As the most heavily populated areas in the world, coastal zones host the majority and some of the most important human settlements, infrastructures and economic activities. Harbour and coastal structures are essential to the above, facilitating the transport of people and goods through ports, and protecting low-lying areas against flooding and erosion. While these structures were previously based on relatively rigid concepts about service life, at present, the design-or the upgrading-of these structures should effectively proof them against future pressures, enhancing their resilience and long-term sustainability. This Special Issue brings together a versatile collection of articles on the modelling of harbour and coastal structures, covering a wide array of topics on the design of such structures through a study of their interactions with waves and coastal morphology, as well as their role in coastal protection and harbour design in present and future climates.

This book was released on 2015-12-09 with total page 126 pages. Available in PDF, EPUB and Kindle. Book excerpt: Sediment transport is a significant part of the scientific area of river hydraulics. Therefore, the first section of the present book presents effects of sediment transport on hydraulic structures, that concern alluvial channel hydraulics. The second section refers to a serious consequence of river sediment transport, namely reservoir sedimentation. Sediment transported in a river originates from the corresponding basin, that is eroded by rainfall water. Hence, the quantification of soil erosion is also addressed in the second section. While soil erosion is the original physical process that causes reservoir sedimentation, the latter process may increase coastal erosion in case that the river feeding the reservoir, discharges its water into the sea. So, the effect of reservoir sedimentation on coastal erosion is further treated in the second section. Finally, the third section of the book is dedicated to the phenomenon of local scour around bridge piers, in particular the conditions of ice cover.
