In the distant past, a course of the Ganges river used to reach the Bay of Bengal through the Dhaleshwari river. In the 20th century the water table and river became polluted by polythenes [clarification needed] and other hazardous substances from demolished buildings near the river banks.. The course of the Padma, as the main course of the Ganges is known in Bangladesh, changed . Harirampur, Shibalaya and Daulatpur thanas of Manikgonj District have been subjected to severe erosion by the river Jamuna, Padma and Dhaleshwari. Erosion continued along the 87 km long banks under these thanas. In the last five years eleven educational institutions, nine mosques, one health complex and six river ports went into the water. Protick, a lover of rivers and an admirer of “good old American road trip–style photography,” began wandering the length of the Padma River, starting in . In Bangladesh, the Brahmaputra is joined by the Teesta River (or Tista), one of its largest tributaries. Below the Tista, the Brahmaputra splits into two distributary branches. The western branch, which contains the majority of the river's flow, continues due south as the Jamuna (Jomuna) to merge with the lower Ganga, called the Padma River (Pôdda).The eastern branch, formerly the larger, but.

Length-average bank erosion rates are higher in the Jamuna, Padma, and Lower Meghna rivers compared to the Ganges and Upper Meghna rivers (Sarker et al., ). The 'Prediction of Riverbank Erosion the Ganges and the Padma rivers in 2009 book the Jamuna, the Ganges and the Padma Rivers in ' report described the loss of an estimatedhectares ( square miles) of land through erosion since as 'one of the major natural disasters in Bangladesh'.
An area of land roughly five times the size of Prediction of river bank erosion along the Jamuna has been lost to the Padma. Jamuna River is characterized by its extremely dynamic and unstable alluvial channels.
This km long braided river is located in lowest reach of the Brahmaputra River in Bangladesh. The Brahmaputra River catchment supplies enormous quantities of. The bank erosion of the Jamuna decreased slightly ranging from to hectares per year in last decade. Padma and Jamuna are rivers that flow within few meters of height in : Md.
Tariqul Islam. A study on River Bank Erosion of Jamuna River This study is aimed at quantifying the actual rates of bank erosion along the river Jamuna based on time series analysis of satellite images.
This work also focuses on pattern of the change of channel alignment and identification of the reaches which are LANDSAT (LT) 5 30m x 30m -The analysis of river bank erosion along Sieu river.

By developing a national level prediction system and proper guidelines for addressing the causes and impacts of river erosion, the process could be made much easier and a lot of money could be.
1. Introduction. Bangladesh is a riverine country with more than 7 percent of its lands occupied by river systems (Hossain et al., ).The bed and banks of major rivers of Bangladesh which include Jamuna, Ganges, Padma, and the Lower Meghna rivers primarily compose of alluvial materials, with their channels characterized by highly dynamic behavior (CEGIS, ).

Google Scholar. Erosion and deposition statistics of the Ganges indicated that 57˚km2 of land was lost along the right bank whereas around 59˚ km2 was gained along the left bank during the perio–(ewan et˚al.
), the course of Padma in Bangladesh, the most sever riverbank erosion have been observed in. Along the right and left bank of the Ganges, erosion rates are 56m and 20m per year respectively, which is lower than the rates observed in the Jamuna.
The width of the river varied from to 10 km in and from to km in Prediction of bank erosion rate along Jamuna River, Bangladesh The bank line migration of the Jamuna left bank downstream of Bahadurabad calculated from SPOT images indicate that the bank erosion rates vary along the bend and the maximum erosion occurred at the downstream end of the bend (DELFT/DHI, ).
Bangladesh has predominantly four major river systems. Ganges (Padma) River is one of the prominent rivers which support the life and livelihoods of millions of people in Bangladesh. The riverine area of Bangladesh has always faced some changing stages for radical accretion and erosion of lands.
Areas of erosion and deposition were determined from successive changes in the bankline. The Ganga/Ganges 1 is an important river system in South Asia which supports the life and livelihoods of millions of people both in India and Bangladesh.
The system has a number of names throughout its length. Below its confluence with the Brahmaputra at Aricha it is known as the Padma, which in turn merges with the Upper Meghna at Chandpur below which the channel is known as the. Cegis has developed a unique tool using timelapse of satellite images to predict riverbank erosion in the Jamuna, the Ganges and the Padma rivers for the upcoming year.
SinceCegis has been predicting riverbank erosion in the major rivers in Bangladesh with adequate accuracy in collaboration with the Bangladesh Water Development Board (BWDB).
In addition to vast quantities of water, these rivers carry about billion tons of sediment every year and are responsible for the prevalence of flooding and riverbank erosion in Bangladesh.
Vulnerable Rivers: According to Banglapedia, The following rivers are vulnerable for bank erosion. Jamuna Ganga Padma Brahmaputra Factors that. According to CEGIS, hac of land had been eroded along the Brahmaputra, 27, hac along the Padma hac along their distributaries between and (IRIN, ).
bank erosion rates and tried to relate the radius of curvature and width of curved anabranches with bank erosion rates following the method of Hickin and Nanson . Estimated bank erosion by Hickin and Nanson’s method showed much smaller values than the observed erosion rate on the Jamuna river.
Similar analyses was carried out by Theme et. Ganges-Padma River System one of the three major river systems of Bangladesh. The bengal delta occupies a unique position among the larger deltas of the world for its varied and complex river and drainage whole delta is criss-crossed by innumerable large and small channels of which some are decaying, some are active, while some others are being drained only by the tidal flow.
Moving Coastlines: Emergence and Use of Land in the Ganges-Brahmaputra-Meghna Estuary by Koen de Wilde is a 54 minute lecture on migration and coastal erosion that is well worth viewing, as many dimensions of migration considered in it are relevant to riverbank erosion.
The Padma: bank erosion in the padma is governed by the planform characteristics of a wandering river. The braided reach of the river is eroding along both banks, while the meandering reaches erode only the outer banks.
The width of the river varied from to km during and from to km during Due to riverbank erosion, people are forced to migrate from their places of origin to other places. Major rivers like the Jamuna, the Ganges and the Padma gradually destroyed around square km floodplains making million people homeless since (CEGIS, ).
A study showed that bank erosion along the Padma river during – is 66, hectares. Riverbank erosion in the Padma river is a perennial problem and is considered as a natural disaster in Bangladesh, this river causes loss of lots of lands and livelihoods.
Riverbank erosion is the wearing away of the banks of a stream or river through its flooding, meanderings, or general e rivers and streams are dynamic systems, they are constantly changing and affecting riverbank soil natural process of riverbank erosion can produce favorable outcomes such as the formation of productive floodplains and alluvial terraces.
CEGIS, JMREMP () Prediction of River Bank Erosion along the Jamuna, the Ganges and the Padma Rivers in The Jamuna-Meghna River Erosion Mitigation Project was developed to sustain economic growth and poverty reduction and to provide livelihood security in areas threatened by riverbank erosion.
It sought to mitigate progressive riverbank erosion through the construction of riverbank protection, in response to the dynamic behavior and morphological changes of the Jamuna and Meghna rivers. The Ganges (/ ˈ ɡ æ n dʒ iː z / GAN-jeez) or Ganga (/ ˈ ɡ ʌ ŋ ɡ ə / GUNG-gə, Hindustani: [ˈɡəŋɡaː]) is a trans-boundary river of Asia which flows through India and 2, km (1, mi) river originates from the Gangotri Glacier of western Himalayas in the Indian state of Uttarakhand, and flows south and east through the Gangetic Plain of India and Bangladesh.
Hore has more than 10 years of experiences in the field of river morphology, hydrology, river bank erosion and vulnerability analysis in Bangladesh. He has successfully completed a few water resources management and morphological studies on the major rivers of Bangladesh, among which the most noteworthy are the "Prediction of River Bank Erosion and Morphological Changes along the Jamuna.
The Ganges River, also called Ganga, is a river located in northern India that flows toward the border with Bangladesh ().It is the longest river in India and flows for around 1, miles (2, km) from the Himalayan Mountains to the Bay of Bengal.
The river has the second greatest water discharge in the world, and its basin is the most heavily populated in the world with over million. Various river resource and regulatory agency management guidelines (Flosi et al. McCullah and GrayEPA ) address bank erosion processes at the scale of an identified erosion site even though channel bank erosion is a river management issue best addressed at the watershed or ecosystem scale.
Rarely is the spatial extent or. Aricha. The length of the bank line exposed to erosion is about km along the right bank and km along the left bank. In terms of erodibility, bank materials of the right and left banks have similar characteristics. The Jamuna River is a braided river having a braiding index of 5 to 6.
Figure Right Banklines of Jamuna River from to Figure Historical Bankline and Planform Changes of Jamuna River near the study area (Titporol and Debdanga during Figure Study Area showing the channels of the Jamuna River Figure Titporol Revetment along the Right Bank of Jamuna River.
The course of the Ganges along the Northern river-front of West Bengal has been fast changing due to unabated bank erosion, especially over the last few decades. The Ganges in Malda district in the upstream of Farakka Barrage has been undergoing extensive erosion along the left bank even though it has been strongly protected (Figure 7 *).
River Bank Protection Amrapalli Garanaik Joel Sholtes CIVE – Ap 1. Bank Degradation: Cause and Effect Bank erosion is a natural process in stable rivers; however, it can become accelerated and exacerbated by direct and indirect human impacts.
• Bank. Keywords: Padma river, bank erosion, left bankline migration, Harirampur, Bangladesh 1. Introduction The bank erosion is a process which largely controlled by river dynamics. More than rivers including the Jamuna, the Padma and the Meghna flow through Bangladesh draining.
We evaluate links between climate and simulated river bank erosion for one of the world's largest rivers, the Mekong. We employ a process-based model to reconstruct multidecadal time series of bank erosion at study sites within the Mekong's two main hydrological response zones, defining a new parameter, accumulated excess runoff (AER), pertinent to bank erosion.
RIVER BANK EROSION, IT’S EFFECT ON LIVELIHOOD AND LOCAL ADAPTATION STRATEGIES IN CLIMATE CHANGE CONTEXT: A CASE STUDY ALONG THE JAMUNA RIVER. Raimangal River (Bengali: রায়মঙ্গল নদী) is a tidal estuarine river in and around the Sundarbans in South 24 Parganas district in the Indian state of West Bengal and Satkhira District in Bangladesh.
The Ichamati breaks up into several distributaries below Hingalganj the chief of which are the Raimangal, Bidya, Jhilla, Kalindi and Jamuna. Torsa River (also spelt Torsha and also known as Kambu Maqu, Machu and Amo Chhu) rises from the Chumbi Valley in Tibet, China, where it is known as flows into Bhutan, where it is known as the Amo has total length of kilometres ( mi), out of which kilometres (70 mi) is in China and kilometres (90 mi) in Bhutan before flowing into the northern part of West Bengal.
river erosion risk map in use in EWS in the country. To generate erosion prediction results initially for the Jamuna and later for the Ganges and the Padma River, the Government of Bangladesh established the Center for Environmental and Geographic Information Services (CEGIS) as a .The Brahmaputra (/ ˌ b r ɑː m ə ˈ p uː t r ə /), called Yarlung Tsangpo in Tibet, Siang/Dihang River in Arunachal Pradesh and Luit, Dilao in Assam, is a trans-boundary river which flows through Tibet, India and Bangladesh.
[a] It is the ninth largest river in the world by discharge, and the 15th longest. Brahmaputra Dilao, Lauhitya The Brahmaputra in Guwahati, Assam, India Path of. Plants suitable for river banks must be able to survive occasional flooding and possible erosion issues.
Some great options and cautions are discussed in this article. Choosing Plants for River Banks. Many homeowners visualize a long expanse of lawn going down to the river, providing unobstructed views and velvety green expanses.
