Book excerpt: Rainfall, snow-, and glacial melt throughout the Himalaya control river discharge, which is vital for maintaining agriculture, drinking water and hydropower generation. However, the spatiotemporal contribution of these discharge components to Himalayan rivers is not well understood, mainly because of the scarcity of ground-based observations. Consequently, there is also little known about the triggers and sources of peak sediment flux events, which account for extensive hydropower reservoir filling and turbine abrasion. We therefore lack basic information on the distribution of water resources and controls of erosion processes. In this thesis, I employ various methods to assess and quantify general characteristics of and links between precipitation, river discharge, and sediment flux in the Sutlej Valley. First, I analyze daily precipitation data (1998-2007) from 80 weather stations in the western Himalaya, to decipher the distribution of rain- and snowfall. Rainfall magnitude frequency analyses indicate that 40% of the summer rainfall budget is attributed to monsoonal rainstorms, which show higher variability in the orogenic interior than in frontal regions. Combined analysis of rainstorms and sediment flux data of a major Sutlej River tributary indicate that monsoonal rainfall has a first order control on erosion processes in the orogenic interior, despite the dominance of snowfall in this region. Second, I examine the contribution of rainfall, snow and glacial melt to river discharge in the Sutlej Valley (s55,000 km2), based on a distributed hydrological model, which covers the period 2000-2008. To achieve high spatial and daily resolution despite limited ground-based observations the hydrological model is forced by daily remote sensing data, which I adjusted and calibrated with ground station data. The calibration shows that the Tropical Rainfall Measuring Mission (TRMM) 3B42 rainfall product systematically overestimates rainfall in semi-arid and arid regions, increasing with aridity. The model results indicate that snowmelt-derived discharge (74%) is most important during the pre-monsoon season (April to June) whereas rainfall (56%) and glacial melt (17%) dominate the monsoon season (July-September). Therefore, climate change most likely causes a reduction in river discharge during the pre-monsoon season, which especially affects the orogenic interior. Third, I investigate the controls on suspended sediment flux in different parts of the Sutlej catchments, based on daily gauging data from the past decade. In conjunction with meteorological data, earthquake records, and rock strength measurements I find that rainstorms are the most frequent trigger of high-discharge events with peaks in suspended sediment concentrations (SSC) that account for the bulk of the suspended sediment flux. The suspended sediment flux increases downstream, mainly due to increases in runoff. Pronounced erosion along the Himalayan Front occurs throughout the monsoon season, whereas efficient erosion of the orogenic interior is confined to single extreme events. The results of this thesis highlight the importance of snow and glacially derived melt waters in the western Himalaya, where extensive regions receive only limited amounts of monsoonal rainfall. These regions are therefore particularly susceptible to global warming with major implications on the hydrological cycle. However, the sediment discharge data show that infrequent monsoonal rainstorms that pass the orographic barrier of the Higher Himalaya are still the primary trigger of the highest-impact erosion events, despite being subordinate to snow and glacially-derived discharge. These findings may help to predict peak sediment flux events and could underpin the strategic development of preventative measures for hydropower infrastructures.

Book excerpt: Climate change not only involves rising temperatures but it can also alter the hydro-meteorological parameters of a region and the corresponding changes emerging in the various biotic or abiotic environmental features. One of the results of climate change has been the impact on the sediment yield and its transport. These changes have implications for various other environmental components, particularly soils, water bodies, water quality, land productivity, sedimentation processes, glacier dynamics, and risk management strategies to name a few. This volume presents a diverse collection of case studies from researchers across the globe examining the impacts of climate change on river basin management in various geographical, hydrological, and socioeconomic contexts. The case studies yield important insights that can inform strategies to build resilience and adapt river basins to a changing climate.

Book excerpt: "The Liwu River runs a short course; its channel head at the water divide in Taiwan's Central Range is a mere 35 km from its outflow into the Pacific Ocean. But in those short 35 km, the Liwu has carved one of the world's geographic wonders: the spectacular Taroko Gorge with marble and granite walls soaring nearly 1000 m above the river channel. Taroko Gorge was a fitting venue for a 2003 Penrose Conference that addressed the coupled processes of tectonics, climate, and landscape evolution. The young mountains, extreme weather, and dramatic landforms provided an appropriate backdrop to wide-ranging discussions of geomorphic processes, climate and meteorology, sediment generation and transport, the effects of erosion on tectonics, and new analytical and modeling tools used to address these processes and problems. This volume's papers extend that discussion, reaching across fields that have experienced rapid advances in the past decade."--Publisher's website.

Book excerpt: This edited book summarizes numerous research studies on remote sensing and GIS of natural resource management for the Himalaya region done by Indian Institutions and Universities over the last decade. It gives an overview of hydrometeorological studies on Himalayan water resources and addresses concerns in the development of water resources in this region, which is dealing with an increased pressure in population, industrialization and economic development. While the source of some of the major rivers of India are found in the Himalayas, the glaciers and water bodies in the region are continuously shrinking leading to a depletion of water and deterioration of water quality. This is affecting a population of up to 2.5 billion people. The ecosystems have been under threat due to deforestation, loss of biodiversity, expansion of agriculture and settlement, overexploitation of natural resources, habitat loss and fragmentation, poaching, mining, construction of roads and large dams, and unplanned tourism. Spaceborne remote sensing with its ability to provide synoptic and repetitive coverage has emerged as a powerful tool for assessment and monitoring of the Himalayan resources and phenomena. This work serves as a resource to students, researchers, scientists, professionals, and policy makers both in India and on a global level.

Available in PDF, EPUB and Kindle. Book excerpt: Scientific evidence shows that most glaciers in South Asia's Hindu Kush Himalayan region are retreating, but the consequences for the region's water supply are unclear, this report finds. The Hindu Kush Himalayan region is the location of several of Asia's great river systems, which provide water for drinking, irrigation, and other uses for about 1.5 billion people. Recent studies show that at lower elevations, glacial retreat is unlikely to cause significant changes in water availability over the next several decades, but other factors, including groundwater depletion and increasing human water use, could have a greater impact. Higher elevation areas could experience altered water flow in some river basins if current rates of glacial retreat continue, but shifts in the location, intensity, and variability of rain and snow due to climate change will likely have a greater impact on regional water supplies. Himalayan Glaciers: Climate Change, Water Resources, and Water Security makes recommendations and sets guidelines for the future of climate change and water security in the Himalayan Region. This report emphasizes that social changes, such as changing patterns of water use and water management decisions, are likely to have at least as much of an impact on water demand as environmental factors do on water supply. Water scarcity will likely affect the rural and urban poor most severely, as these groups have the least capacity to move to new locations as needed. It is predicted that the region will become increasingly urbanized as cities expand to absorb migrants in search of economic opportunities. As living standards and populations rise, water use will likely increase-for example, as more people have diets rich in meat, more water will be needed for agricultural use. The effects of future climate change could further exacerbate water stress. Himalayan Glaciers: Climate Change, Water Resources, and Water Security explains that changes in the availability of water resources could play an increasing role in political tensions, especially if existing water management institutions do not better account for the social, economic, and ecological complexities of the region. To effectively respond to the effects of climate change, water management systems will need to take into account the social, economic, and ecological complexities of the region. This means it will be important to expand research and monitoring programs to gather more detailed, consistent, and accurate data on demographics, water supply, demand, and scarcity.

Available in PDF, EPUB and Kindle. Book excerpt: The Himalaya mountains contain not only one of the largest concentrations of ice outside the polar regions, but contribute to the hydrological requirements of large populations spread over seven nations. The exceptionally high elevations of this low-latitude cryosphere presents a natural laboratory and archives to study climate–tectonics interactions as well as regional v. global climate influences. The existing base-level data on the Himalayan cryosphere are highly variable. Several climate fluctuations occurred during the late Quaternary (MIS1–MIS5, especially the last c. 100 ka), which led to the evolution of the Himalayan landscape. Detailed studies of these archives, along with those of the present cryosphere and related hydrosphere, are essential for understanding the controls on present and future hydrology of the glacial-fed mountain rivers. This volume, a follow-up of the XII International Symposium on Antarctic Earth Science, Goa (A SCAR symposium), provides new data from locales spread over the entire Himalaya region and from Tibet. It provides a glimpse of the late Quaternary cryosphere, as well as a discussion in the last section on sustainability in the context of geohazard mitigations as well as the hydrological budget.

This book was released on 2019 with total page 100 pages. Available in PDF, EPUB and Kindle. Book excerpt: Anthropogenic climate change, particularly through increased greenhouse gas (GHG) emissions, is projected to considerably impact 21st century precipitation distribution, altering fluvial processes such as sediment dynamics and riverine water discharge, worldwide. Changes in the magnitude of fluvial water and sediment fluxes can have profound impacts on the functioning and connectivity of earth's natural systems. This study is focused on isolating the impacts of GHG-induced future climate change on riverine water discharge and suspended sediment fluxes in the 21st century at a global scale. A global-scale hydro-geomorphic model (WBMsed) was forced with precipitation and temperature projections generated from five General Circulation Models (GCMs), each driven by four Representative Concentration Pathways (RCPs). The results, based on an ensemble of model outputs, revealed that global river discharge and sediment dynamics are considerably impacted by anthropogenic climate change in the 21st century. Despite substantial regional heterogeneity, a global net increase is projected for both river discharge and sediment flux in the 21st century under all RCP scenarios. Increases are larger and more variable with increasing levels of GHG concentrations in the atmosphere. At the end of this century, climate change under RCP 2.6 is projected to cause approximately 1% increase in global river discharge and 5% increase in global suspended sediment flux. Under RCP 4.5 emission scenario, climate change will lead to a 5.6% increase in river discharge and 7% increase in sediment flux at a global scale. Approximately 5% and 9% increases are projected under RCP 6.0 in global river discharge and sediment flux respectively. Climate changes projected under RCP 8.5 will lead to the largest increases in river discharge and sediment flux (7.3% and 14.7% respectively) at the end of the 21st century. With increased warming, more extreme changes (increasing or decreasing) can be expected in both discharge and sediment flux. Also, the number of rivers with statistically significant trends in either direction increases with warming. In addition to magnitudes, inter-annual variability in both global river discharge and sediment fluxes also increase with increasing RCPs. Changes in sediment flux closely follow the patterns predicted for discharge, and are mostly driven by climate warming induced spatial and temporal variation in precipitation. However, the relationship between discharge and sediment flux was found to be non-linear both in space and time, demonstrating the utility of explicit modeling of both hydrology and geomorphology.

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.

Available in PDF, EPUB and Kindle. Book excerpt: This thesis deals with the role of precipitation on erosion and landscape formation in the Nepal Himalayas. I investigate all successive steps involved in the erosion process: 1) Starting from the evaluation of precipitation datasets, 2) the transfer of precipitation to river discharge, 3) the mobilization and transport of material out of the mountain range, 4) and finally, erosion constrains over longer time-scales. In order to make this possible I will exploit multiple datasets such as precipitation, river discharge, suspended sediment concentrations of rivers and cosmogenic nuclide analysis. The work is structured in four research publications, which build the principle content of this manuscript. I show that the dataset derived from the interpolation of rain gauge data performs best in the Himalayas. With the evaluation of precipitation data, I set the basis for the further analysis in order to better understand erosion processes. I demonstrate the importance of an until now unconsidered, major compartment of the Himalayan discharge cycle, which I identify as a fractured basement aquifer, and estimate the snow and ice melt contribution to the Himalayan rivers. Erosion rates calculated from suspended sediment fluxes and cosmogenic nuclide analysis range between 0.1 and 6 mm/yr. The rivers in the Nepal Himalayas are supply limited and the hillslopes as contributing source are transport limited. Last I show that over several thousand years erosion is not related with precipitation, but with relief, and I demonstrate that the landscape in the Himalayas is not in equilibrium.
