Sperm and egg quality of catla Catla catla and rui Labeo rohita were investigated in Brahmaputra and Sarker Hatchery, Mymensingh, Bangladesh over two spawning seasons as early (March to May) and peak (June to August ). In both hatcheries, catla and rui produced nearly 90% motile sperms as well as higher sperm concentration (catla: Brahmaputra hatchery. 2533.33 ± 119.65 million mL-1 and Sarker hatchery, 2658.89 ± 76.55 million mL-1; rui: Brahmaputra hatchery, 2856.67 ± 67.57 million mL-1 and Sarker hatchery, 2811.67 ± 51.90 million mL'1), seminal pH (catla: Brahmaputra hatchery, 7.41 ± 0.06 and Sarker hatchery, 7.41 ± 0.06; rui: Brahmaputra hatchery, 7.39 ± 0.05 and Sarker hatchery, 7.35 ± 0.05) and fertilizability in catla were 88% and In rui 92% in both hatcheries in the peak season. The occurrence of opaque eggs in catla and rui was 12% and 8% in both hatcheries in the peak season, respectively. The present study points to the fact that the quality of fish sperm and egg depends on seasons Asiat. Soc. Bangladesh, Sci. 40(2): 231-241, December 2014

Abstract:
Abstract The Brahmaputra River of South Asia is the fourth largest river in the world in terms of annual discharge. The lower Brahmaputra River basin is susceptible to catastrophic flooding with major social, economic, and public health impacts. There is relatively little rainfall and snowpack information for the watershed, and the system is poorly understood hydrologically. Using a combination of available remotely sensed and gauge data, this study analyzes snow cover, rainfall, and monsoon period discharge for a 14-yr time period (1986–99). It is found that interannual rainfall variability is low and is a weak predictor of monsoon discharge volumes. Strong evidence is found, however, that maximum spring snow cover in the upper Brahmaputra basin is a good predictor of the monsoon flood volume. Despite the temporal and spatial limitations of the data, this study’s analysis demonstrates the potential for developing an empirical tool for predicting large flood events that may allow an annual early window for mitigating flood damages in the lower Brahmaputra basin, home to 300 million people.

Abstract:
The study was conducted to investigate the surface water quality and concentration of heavy metals in water and fish of the Balu and Brahmaputra rivers near to Demra in Dhaka city and BAU campus in Mymensingh respectively. Water samples were collected in distinct three sampling sites which were denoted as Station 1, Station 2 and Station 3. In Balu and Brahmaputra river, analysis of physicochemical parameters like temperature, transparency, pH, electrical conductivity (EC), total dissolved solid (TDS), dissolved oxygen (DO), biochemical oxygen demand (BOD) and alkalinity and the concentration of heavy metals (Pb, Cr, Cd, Cu, Ni, Zn) both water and three fish (Mastacembelus armatus, Channa punctatus and Mystus vittatus) species were analyzed. The comparative study reported that some physicochemical parameters like TDS (704±8.54 mg/l); EC (1043±39.15 mg/l), BOD (22±3 mg/l), and alkalinity (311±6.56 mg/l) of Balu river water were found much higher than Brahmaputra river where as transparency (10±0.25 cm), and DO (1.7±0.36 mg/l) lower than Brahmaputra river water. Temperature and PH were close to standard. The comparative study also revealed that the concentrations of heavy metals like Pb (0.032±0.003 mg/l), Cr (0.02±0.003 mg/l), Cd (0.02±0.005 mg/l), Ni (0.04±0.004 mg/l), Zn (0.08±0.005 mg/l) and Cu (0.01±0.002 mg/l) of Balu river water were higher than Brahmaputra River. In M. armatus, C. punctatus and M. vittatus, the concentration of heavy metals like Pb (0.85, 0.92 and 0.89 mg/kg), Cd (0.45, 0.48 and 0.51 mg/kg), Cr (0.72, 0.76 and 0.51 mg/kg), Cu (0.39, 0.38 and 0.35 mg/kg), Ni (0.95, 0.86 and 0.81 mg/kg) and Zn (1.17, 1.21 and 1.25 mg/kg) were noted in Balu river which were much higher than those of Brahmaputra river. Bioaccumulation of heavy metals in fish can increase with the increase of heavy metals in water if pollutants discharge simultaneously. The results suggested that the water in the Balu river was polluted and not suitable for human consumption and aquaculture. On the other hand water in the Brahmaputra river was usable for aquaculture and irrigation but gradually degrade its quality by growing industries and untreated waste from municipalities.Progressive Agriculture 27 (4): 444-452, 2016

Abstract:
Time series models are used in hydrology for the generation of river flow data. The development of such a model, namely deseasonalized Autoregressive Moving Average (ARMA), for the generation of 10-day flows of the Brahmaputra River in Bangladesh is described. The model was fitted following systematic stages of identification, estimation and diagnostic checking of model building. A negative power transformation for the Brahmaputra flow was found to be necessary for model construction. The seasonality of the flow was removed by Fourier analysis using five harmonics for 10-day means and 13 harmonics for standard deviations. The fitted model was ARMA (1, 3) having one autoregressive parameter and three moving average parameters. The validation forecasts made with the model indicated that the deseasonalized ARMA model could capture the 10-day variability of the Brahmaputra flow reasonably well. To further validate and verify the model 200 synthetic flow sequences, each with a length of 50 years, were generated. The fitted ARMA model was found to be capable of preserving both short-term statistics (variance and autocorrelation) and long-term statistics (Hurst coefficient and rescaled adjusted range) of the historic Brahmaputra flow.

Abstract:
A field survey was conducted for three consecutive years, 2015–17 to assess the diversity of freshwater molluscs (Gastropoda and Bivalvia) of the upper Brahmaputra Basin in Assam, India. Altogether, 18 gastropods and 27 bivalve species representing nine families were recorded from 17 sampling stations comprising small to large tributaries and wetlands in the flood-plains covering a total geographical area of approximately 3,500km2. A large fraction (15.55%) of the collected mollusc species are new records from the upper Brahmaputra Basin of Assam. Rarity in the occurrence of freshwater mollusc was confirmed with singleton and doubleton species accounting for 6.66% and unique species accounting for 35.55% of the total species recorded. It was observed that most of the mollusc species of the upper Brahmaputra Basin are either in the ‘Least Concern’ or ‘Data Deficient’ category of the IUCN Red List; except for Lymnaea ovalior (Annandale & Prashad, 1921) and Sphaerium austeni Prashad, 1921 assessed as ‘Vulnerable’ and ‘Near Threatened’, respectively. A significant trend in the diversity in terms of species richness and composition was observed across the sampling stations of the northern basin and southern basin of the river Brahmaputra.

Abstract:
The Brahmaputra River is the largest tropical river in India that flows along the Himalayan regions and it is the lifeline of millions of people. Metal fractionation in the Brahmaputra River’s surface sediments and its correlation with turbidity are assessed in this study. The interaction between metal fractions and the overlying water is studied using multivariate statistical analyses. The strong positive correlation between NH4 of the overlying water and the exchangeable fractions in sediments signifies that the metals in the exchangeable fractions can be substituted by NH4. Subsequently, these metals can be released into the overlying water. The fluctuation in turbidity from 73 to 875 NTU indicates a large variation in the suspended matter concentration, and a higher concentration of suspended matter could provide attachment sites for pollutants such as metals. Significant variation in turbidity manifests a potentially high risk of pollution. In addition, the observation of local people along the Brahmaputra River turning its color to muddy indicates the need for continuous monitoring of water quality and an assessment of pollution is crucial. Although the Brahmaputra River’s risk assessment code is at low risk, the exchangeable fractions of Ni and Zn are present at all sites. Thus, the Brahmaputra River requires early preventive measures and management strategies to control metal pollution. This study contributes to an understanding of the fluctuation of turbidity of a tropical river. We provide baseline data for policymakers, and the importance of further intensive studies on metal pollution in the Himalayan Rivers is highlighted.

Abstract:
Abstract This paper describes a fully automated scheme that has provided calibrated 1–10-day ensemble river discharge forecasts and predictions of severe flooding of the Brahmaputra and Ganges Rivers as they flow into Bangladesh; it has been operational since 2003. The Bangladesh forecasting problem poses unique challenges because of the frequent life-threatening flooding of the country and because of the absence of upstream flow data from India means that the Ganges and Brahmaputra basins must be treated as if they are ungauged. The meteorological–hydrological forecast model is a hydrologic multimodel initialized by NASA and NOAA precipitation products, whose states and fluxes are forecasted forward using calibrated European Centre for Medium-Range Weather Forecasts ensemble prediction system products, and conditionally postprocessed to produce calibrated probabilistic forecasts of river discharge at the entrance points of the Ganges and Brahmaputra into Bangladesh. Forecasts with 1–10-day horizons are presented for the summers of 2003–07. Objective verification shows that the forecast system significantly outperforms both a climatological and persistence forecast at all lead times. All severe flooding events were operationally forecast with significant probability at the 10-day horizon, including the extensive flooding of the Brahmaputra in 2004 and 2007, with the latter providing advanced lead-time warnings for the evacuation of vulnerable residents.

Abstract:
This study investigates the bar morphology, sediment properties and amount of sediment yield in relation to channel dynamics of the Brahmaputra-Jamuna River over a decadal timescale (1987-1997) using digital satellite images and field observations. Two typical reaches were chosen for study, representing the upper widest reach (Bahadurabad Ghat Reach) and the lower narrowest reach (Jamuna Bridge Reach) of the Brahmaputra-Jamuna River. Erosion and accretion of channel banks appears to be the root of all the processes of braiding. Channel banks of both the study reaches are more severely affected by erosion than accretion and both banks are retreating each year. An increased amount of sediment load in excess of transport competence immediately downstream node of a flow convergence seems to initiate the process of development of a braid bar. The process of braiding and channel expansion appears to be interdependent which reveals 'chicken and egg' relationships between them. Bars are usually diamond or triangular-shaped in plan view and their long axes are oriented parallel to the channel. The bars of the Brahmaputra-Jamuna River are grouped into two types, island and attached according to their morphological characteristics, this classification provides increased functional capability with less ambiguity. Between these two types, island bars are prominent features relative to attached bars. Both forms of bars are characterised by three level successions of topographic features although they constantly change their position with few localities left to be permanently stable. Most of the bars are submerged during high flow and erosion tends to occur at the upstream end of a bar and deposition on its downstream, while during falling stage the upstream end and lateral margins of bars receive sediment deposits and the downstream faces occasional erosion. There are considerable mutual adjustments in bar erosion and deposition between the two forms of bars. During the decadal timescale both the study reaches are accreted by bar deposition and the Brahmaputra-Jamuna River is in a condition of active aggradation. Sediment size characteristics at both banks and bars are dominated by very fine sand to fine sand particles. Very little discernible variability of particle size parameters and mineralogical compositions between the banks and bars indicate channel bank material as the potential source of bar sediments. There is no evidence of downstream diminution of sediment particle size, indeed the study results reveal a slight trend of downstream coarsening. Estimation of reach-scale sediment balance using cross-sections and satellite images provides information of quality comparable to that of measured cross-sections or a sediment continuity approach, and demonstrates a preferred method for sediment balance estimations in the Brahmaputra-Jamuna River. These findings suggest that analysis of digital satellite images has an advantage over the traditional field-based studies while a very intensive field work program supplements ground truth information that fills in the drawbacks of satellite imagery. Combination of both methods and relevant computer analysis is useful as a means of mapping and quantifying spatial and temporal change of channel morphology, and as a means of measuring some of the variables which promote, sustain and control channel braiding over annual-decadal timescales.

Abstract:
This study investigated contemporary floodplain sedimentation, interactions between sediment, vegetation, and agricultural land use, and the potential utility for a Bayesian Network Decision Support System (BNDSS) to assist farmers in making better decisions concerning agricultural land use. The research was performed around Bara Bania Mouza (village) under Daulotpur Uazila in Manikgong district of the Brahmaputra-Jamuna floodplain in Bangladesh. This area was selected because it is representative of the young and active floodplain, where the land is flooded and receives overbank sediment deposition every year. The research employed exploratory data analysis and Bayesian approaches to identify and investigate causal relationships among the variables and so support probabilistic inferences. The study investigated two distinctly different types of monsoonal flood: a bonna (an abnormally large flood that occurred in 2007) and a barsho (a normal flood that occurred in 2008). Data on landforms, flood hydraulics, sediment dynamics (suspended sediment concentrations and sediment accumulation rates), and vegetation, rain-fed flooding, land use and farmers knowledge on soil suitability and cropping were collected through field surveys. The results establish how flow and sediment dynamics contrast as a function of landform and demonstrate that the thickness and calibre of deposited sediment strongly influence farmers' decisions on which and how many crops to cultivate on a given plot. Natural vegetation (e.g. sun grass) and certain agricultural crops were shown to have huge potential for use in slowing floodwater and trapping coarse grain sediment particles in buffer stripes. Marked contrasts were also observed between the characteristics of sediment deposited by rain-fed and river water flooding. Questionnaires and semi-structured interviews revealed that although farmers have profound knowledge on soil types and crop associations their methods are crude and little or no science is involved in the investigation of soil and sediment properties. Despite this, farmers' estimates of soil properties proved to be reasonably accurate with the estimate of particle size differing by only <15% from the results of laboratory particle size analysis. This suggests that the farmers' methods do give reliable indications of key soil attributes, but that they could be improved if scientific information was integrated with their local knowledge. A Bayesian approach provides a means of achieving this and the BNDSS developed in this study was found to produce good results when compared to field observations and backward propagation indicated that for better decision making it is crucial to consider both physical and socioeconomic variables. The findings of the research reported in this thesis show that sedimentation has major impacts on agricultural land use dynamics in the Brahmaputra-Jamuna floodplain and that both natural vegetation and agricultural crops significantly influence sediment movement and the way that deposition is distributed over the floodplain. In a wider context, flood, sediment, vegetation and agricultural land use dynamics are controlled by complex set of both physical and human phenomena that are challenging to describe, integrate, analyse and interpret in a single study. In light of this, it is not surprising that the findings presented in this thesis highlight important gaps in knowledge that need to be addressed through further research.

Abstract:
This thesis investigates the interactions between tectonics and erosion in the eastern Himalaya through the study of paleo-Brahmaputra deposits in the foreland basin. Sediment depositional dating of two sedimentary sections is performed using magnetostratigraphy, apatite fission-track and luminescence dating. Provenance analysis using zircon and apatite U-Pb dating allows the reconstruction of the Miocene-Quaternary paleo-drainage of the Brahmaputra River and the documentation of the tectonic evolution of two poorly understood Himalayan features: the Shillong Plateau and the Namche Barwa Syntaxis. The Shillong Plateau is the only elevated topography in the Himalayan foreland and the timing of its surface uplift is debated. Decoupling between of the time of rock exhumation and surface uplift has been explained by differences in rock erodibilities of the plateau between the Shillong Precambrian basement and the overlying Cenozoic sedimentary rock. New detrital zircon U-Pb data and lithospheric stress field modelling presented here date the rise of the Plateau between 5.2 Ma and 4.4 Ma leading to the redirection of the Brahmaputra River at that time, and the role of tectonics in the rise of the plateau is invoked. The Namche Barwa syntaxis is located at the eastern Himalayan termination and its development is widely debated. It has been subjected to anomalously young (< 10 Ma) peak metamorphism, and unusually high exhumation rates (up to 10 mm/yr), in comparison with the Himalayan main arc of the orogen. However, the timing of the onset of rapid exhumation of the Namche Barwa syntaxis is poorly constrained (between 10 and 3 Ma). Focusing on the proximal detrital record of material eroded from the syntaxis, new rutile U-Pb, white-mica 40Ar/39Ar and zircon fission-track data, together with published data are incorporated in a thermokinematic model which suggests an older onset ( > 10 Ma) of rapid exhumation, and at high but not extreme rates (< 5 mm/yr).

Abstract:
For the first time in the history of mangroves, the Ganges-Brahmaputra delta in particular, this doctoral research aims to quantify forest change with an unprecedented period spanning from 1906 to 2014. The world’s largest mangroves – the Sundarbans of the Ganges-Brahmaputra delta accounts for 4.5% of the world’s mangrove forests, has been used as the test site. The research quantified the forest change into two distinct strands: (a) an assessment of vegetation dynamics over 106-years (1906-2012) in the Bangladesh Sundarbans and (b) a 42-years long (1973-2014) satellite imagery-based assessment of spatial change patterns of the Sundarbans. To address those objectives, this study used three different datasets: (1) a three month long extensive ground survey in 2011-12; (2) synthesis of six epochs of vegetation estimates: 1906-10, 1923-26, 1957-59, 1982-84, 1996-97 and 2011-12; and (3) mapping forest and forest types from six epochs of Landsat time-series: 1973 (MSS1), 1979 (MSS3), 1989 (ETM+ 7), 2010 (TM5), and 2014 (OLI8) using ground-based training samples and high (5m-RapidEye) to very high (<5m-GeoEye, IKONOS, QuickBird, OrbView) spatial resolution optical imagery spanning from 1967 to 2014. Ground survey of 164 sample plots, 400 m2 per plot, has recorded 21 tree species from 33 recorded plant species having median values of stem diameter and total height estimated to 3 cm and 5.4 m, respectively. Out of 47,293 stems, gewa was found dominating (42%) which together with sundri constitute about 80% of the stems. Sundri stems were found to be taller than gewa but opposite in the case of stem median diameter and are significant in both cases. Stocking has declined to 50 stems.ha-1 from 650 stems.ha-1 from ≥20 cm to ≥10 cm diameter. Tree richness, diameter and total height has found declining with increasing salinity. The southeast region of the Bangladesh Sundarbans has recorded the highest diameter and taller stems. Overall, total height of stems has declined while tree mortality from top-dying has increased 4.5 times. Over the last 106-years (1906-2012), a 58% decline of ≥15 cm diameter sundri has been estimated. From 1923-2012, the sundri-dominated forest has declined by 34% while gewa and other-dominated forests have increased by 11% and 24% respectively. Decline in larger diameter stems (≥ 5cm) has provided space for younger stems to grow and dominate which showed an overall increase in stocking of sundri, gewa and other-dominated forest types. These long-term forest change estimates will benefit in understanding ecology and carbon dynamics of mangroves that eventually contribute in UN-led reduced emission from deforestation and forest degradation (REDD+) programmes for mangroves of the Ganges-Brahmaputra delta.

Abstract:
A simple correlation analysis was used to investigate the linear relationships between sea surface temperature (SST) and monthly flow of Ganges and Brahmaputra at the borders of Bangladesh and India using approximately 50 years of river discharge data. Strong correlations were found between the equatorial Pacific SST and boreal summer Ganges discharge from three-month lag to two-month lead times. The El Nio-Southern Oscillation (ENSO) explains Ganges flow variance exceeding 0.95 significance level using both the Nino 3.4 SST correlation and the composites made for El Nio (La Nina) periods. The May SST of the southwest Pacific Ocean to the east of Australia continent has a strong correlation (>0.6) with early summer Ganges discharges. Using a lag correlation analysis of Ganges discharge and SST, we found a steady and continuous development in the Nino 3.4 SST relationship, and a strong correlation with the southwest Pacific SST which is most pronounced three-four months prior to the onset of Asian summer monsoon. These relationships mean that at least 25% of the interannual summer Ganges River discharge variability can be explained by antecedent equatorial and southwest Pacific SST. It provides a possible statistical method for linear forecasting two or three months in advance. The Brahmaputra River discharge, on the other hand, shows weak relationships with tropical SST variability except for the Bay of Bengal and the higher northern latitudes of the Pacific.

Abstract:
Erosional issues in the Brahmaputra River in the eastern Himalayas pose increasing pressure on the nearby societies and ecosystems. With a proceeding climate change and increasing anthropogenic disturbance, predictive models are needed to evaluate the effect on sediment transport. Especially in braided rivers, like the Brahmaputra, sediment transport processes imply high demands on numerical models. The objective is therefore to assess the sensitivity of sediment transport on changed river characteristics in the Brahmaputra River, in order to qualitatively evaluate future possible dynamics. Through the one-dimensional steady state model, HEC-RAS 4.1, the braided river was simplified into a single straight channel to enable an extensive reach (700 km) to be modelled. Since little comparative data were at hand, a literature review gathered independent estimates of each parameter. Their natural variability was applied in the sensitivity analysis, and the model produced a suspended sediment load representing approximately 35% of observed data. The sensitivity analysis showed that the channel bathymetry form had a large impact on the model results, whereas the amount of lateral inflow (both surface and subsurface waters) to the main channel flow had a very small impact. Overall, the suspended sediment load were interpreted to be increasing from a future climate change, while further river regulation could counteract such elevation. Further studies are required concerning the river bathymetry in large scale modelling and to address transport of finer cohesive sediments. This methodology proposes a novel approach on how to analyze sediment transport at a large scale that could be used as a tool to interpret future possible changes and ultimately contribute to a better understanding of sediment transport modelling in the area.

Abstract:
The channels of the great rivers of Bangladesh are highly dynamic and their banklines change continuously, consuming large areas of floodplain and making thousands of people landless. As a result, bank erosion is a serious cause of poverty in Bangladesh. Severe bank retreat associated with net widening of the Jamuna, Padma and Lower Meghna Rivers during the last 50 years has greatly increased the suffering of the people. Changes in the width and planform patterns of these rivers indicate that they have not been operating in dynamic equilibrium. However, the causes of instability and planform metamorphosis remain contested. This is significant as identifying the causes of the observed channel adjustments would be of great interest not only to river scientists and engineers, but also to planners attempting better to manage the nation's natural and human resources. In this context, the research reported in this thesis proposes a working hypothesis that morphological changes in the Jamuna-Padma-Lower Meghna system have occurred in response to disturbance of the fluvial system by the Assam earthquake of 1950. Contemporary documents report that landslides triggered by the earthquake generated about 4.5* 1010 m3 sediment, much of which entered the Brahmaputra River in Assam either directly or via its tributaries. It is proposed that the fine fraction of this sediment (silt and clay) travelled quickly through the system, without disturbing the morphology of the channels, before settling in the Meghna Estuary and Bay of Bengal. In contrast, it is hypothesised that the coarser fraction (sand) took half a century to progress through the system, moving as a wave of bed material load, with a celerity between 10 and 32 kmy-1. Preliminary analyses of historical maps and satellite images, together with records of discharge, water level, sediment transport and cross-sectional form reveals a sequence of morphological changes in the Jamuna-Padma-Lower Meghna system with a downstream phase lag that is commensurate with the celerity of the coarse sediment wave. A conceptual process-response model has been developed to elucidate the relationship between downstream propagation of the sand wave and morphological responses, based on models previously reported in the literature and the sequence of changes observed in the Jamuna River. The model has been validated using morphological responses observed in the Padma and Lower Meghna rivers, which appear to have acted as a downstream continuation of the Jamuna River. Based on the conceptual model, a scheme has also been developed to explain and predict planform responses to changes in sediment supply to a braided river. This scheme is shown to be consistent with earlier models, the responses to increased sediment supply in the great rivers of Bangladesh and those of some very large rivers in China. Once fully validated, the conceptual model and the scheme may be used not only to explain the past behaviour of braided rivers, but also to predict the morphological responses of the large rivers of Bangladesh to future disturbance by, for example, climate change, seismic events or interventions in the fluvial system upstream in India. The capability to make such predictions would be immensely helpful in planning how to manage future channel instability and mitigate its socioeconomic impacts for the benefit of floodplain dwellers and the Nation.
