This present study investigates grain size, sediment dynamics and lateral erosion processes along the Ghaghara River from Faizabad to Deoria, Ganga Plain, India. The grain size analysis reflects that surface sediments have silt (24.50%) and very coarse silty-sand (75.50%) composition. The mean grain size varies from 2.20 to 4.21 ϕ indicating fine s...

The temporal response of global warming and the rise in global temperature on Gangotri, Meru, Thelu, and Swetvarn glaciers of the Garhwal Himalaya region during the last 50 years have been analysed in this chapter. The monitoring of these glaciers was carried out using high- and medium-resolution satellite images of CORONA (KHA), LANDSAT (MSS, TM,...

Gangotri glacier located in the Uttarkashi District of the Garhwal Himalaya, is one of the longest valley glacier. It exhibits Lateral Moraines (LM), Recessional Moraines (RM), Kame Terraces (KT) and Outwash Plains (OWP) as important landforms. The sediments coded in these landforms, provide the information about sedimentary characteristics, and th...

The Reth River is a ground water fed river of Central Ganga Plain, ~107 km long and drains ~391.71 km2. It flows through an incised valley until confluences with the Gomati River. Incision of the river valley has been investigated by using a longitudinal profile, escarpment height and morphology of the valley. The study was executed using Toposheet...

The present study recognizes the various glacial geomorphic features such as Lateral Moraines (LM), Terminal/Recessional Moraines (RM), Outwash Plain Deposits (OWP), Kame Terraces in the study area. The Glacial (Gl) sedimentary environment is dominantly active in the area during ice ages and evolves the landforms. The feld observations and litholog...

The present study aims to access the geomorphic analysis of the Baghain river basin and its implication on landscape evolution. Baghain river originates from the Panna hill, and flows through marginal and central Ganga plain. It empties itself in to Yamuna river near Chilla village, Banda district, Uttar Pradesh. The river basin comprises of three...

The dynamic behavior of glaciers in the Himalayan region produced the landforms, which provide valuable information on the long-term effects of climate change and landscape evolution. The Gangotri glacier, one of the most dynamic and relatively well-documented glacial system, is longest valley glaciers out of 968 glaciers scattered over the Uttarak...

The Kali River is a sixth-order tributary of the Ganga River. It originates near Khatoli town in Muzaffarnagar and confluences with the Ganga River at Kanauj District, Uttar Pradesh. In this study, drainage morphometry, temporal groundwater level observations and precipitation data are used to examine surface and subsurface hydrological conditions....

The landslide trigger by the high slope, weak bedding planes, weathered rocks, and anthropogenic activities. Remote Sensing with Geographical Information System (GIS) techniques were used to prepare susceptibility modeling, thematic maps, and zonation maps of landslide prone area between Joshimath and Karnaprayag.. The measurement and analysis of v...

Gangotri glacier, located in the Uttarkashi district, is one of the longest valley glaciers of the Garhwal Himalaya. It exhibits lateral moraines, recessional moraines, outwash plains, kame terraces, and debris cones. Kame terraces are significant landforms that preserve the climatic records and geological history in their deposits. The sedimentary...

Morphometry is a quantitative approach of analysing linear, areal and relief parameters to understand the role of neotectonic activity in geomorphologic evolution of a river basin. In the present study multi-disciplinary integrated approach using morphometric parameters along with remote sensing and GIS technique have been applied for determining t...

Impact of climate change on glaciers brings the favorable conditions of lakes formation within glacier moraines. These lakes may produce outburst floods and transport the huge amount of debris (debris flow) in downstream settlements. The present study addresses the current knowledge on mass movement activity occurred in the Gangotri glacier area, G...

The current research work deals with the health of Chorabari glacier between 1976 and 2017, using multi spectral and multi dated satellite data series of LANDSAT (MSS, TM, and ETM⁺) and RESOURCESAT II (LISS IV). Result closely reveals that the studied glacier receding continuously with inconsistent rate for the last 41 years and process of receding...

This study assesses the temporal changes of Swetvarn and Thelu glaciers between 1968 and 2019 in Rakvarn glacial valley of Bhagirathi basin. Here we utilized high-resolution satellite images of CORONA KHA (1968), LISS IV (2012) and SENTINEL-2 MSI (2019), along with medium resolution images of LANDSAT TM (1990) and SRTM (2000) to carry out the resea...

This study focuses on hydrogeological processes and subsurface geological activities. The basin area measured is 11,161 km2 with NW-SE sloping trend. Sinuosity Index is 2.7 which show meandering nature. The drainage density, stream frequency and drainage intensity values were 0.62 km−1, 0.23km−1 and 0.37 respectively which implies that low surface...

Flood is the natural disaster worldwide, predominant in Ganga Plain, India. The Ghaghara River Basin with a basin area of 60966 Sq. km., is located in Middle Ganga Plain, Flood hazard in the Ganga Plain region occur due to high discharge of the Ghaghara River and its major tributaries during monsoon season. The present study aim to prepare the floo...

Gangotri Glacier has attracted international attention for its rapid rate of retreat. It is one of the best studied Himalayan glaciers, however there are no unanimous views about the history of climate change for the Gangotri Glacier. We prepared the lithologs/textural logs by making two trenches in the kame terraces and analysed it in detail for s...

The drainage basin of the Kalyani river, a tributary of Gomati river has been mapped and delineated using Survey of India toposheets (1:50,000 scale) and remote sensing satellite data. The digitization, slope map preparation and statistical calculations have been carried out with the help of geographical information system (Arc GIS 10). Kalyani a f...

The Ny-Alesund region is characterised by diversified surface processes which carve the landscape and so exhibits variable and complex landforms. Extensive work has been carried out on climate change using various proxies however no much attention has been paid in understanding the climate events using geomorphological and sedimentological paramete...

Gomati is the sixth order groundwater-fed tributary of Ganga River and lifeline of the Central Ganga Plain region. The total catchment area of the Gomati River basin is more than 30,000 km2.
