The enormous network of rivers comprised in the delta of the Ganges and Brahmaputra frequently furnish examples of the shifting of the beds of streams and the diversion of considerable bodies of water into different channels, with consequent decrease in the flow of others. The general tendency, however, is inevitably to gradual silting up of the smaller rivers by the quantities of alluvium brou...

introduction active mending rivers are the most dynamic and sensitive parts of the fluvial landscapes. meandering rivers suffer a large geomorphic changes during the annual flood events. based on large flood evidences, reconstruction of the channel bed migration will be possible, which is use for evaluation of future evaluation and flood risk assessment in the flood plain areas. the morphologic...

Riparian areas along rivers are essential movement corridors for terrestrial animals. However, the potential role of the dry bed of intermittent rivers as a movement corridor has been largely ignored. In this study, we investigated the use of the dry riverbed, compared with riparian, upland, and unpaved road habitats, by terrestrial vertebrates (mammals, reptiles, and birds) along two intermitt...

A long-term goal of our sediment transport and deposition investigations is to link sediment-transport processes to the formation and preservation of event beds in sediment deposits. The general aim of this project is to investigate how forcing processes affect the sediment-transport dynamics that act to effect the delivery and retention of fine-grained sediment through tidal rivers and in shal...

BACKGROUND In Sri Lanka, the major malaria vector Anopheles culicifacies breeds in pools formed in streams and river beds and it is likely that people living close to such breeding sites are at higher risk of malaria than people living further away. This study was done to quantify the importance of house location relative to vector breeding sites for the occurrence of malaria in order to assess...

The way river morphodynamics influence the preservation of point-bar deposits at multiple scales is not fully understood. Employing time-lapse trajectories natural rivers, a numerical model used here to simulate planform evolutions meander-belt reaches that embody different transformation behaviors and cutoff processes. Proxies for temporal durations are obtained considering surface area over w...

The long-term discharge evolution of branches of rivers can potentially be derived from inactive and fossil river meanders using relations between discharge and channel width and meander dimensions. This evolution is relevant for the understanding of river dynamics and avulsion, and the resulting changes of downstream flooding risks and shipping conveyance. Unfortunately, digitalisation of infi...

The channel of Bhagirathi River is the branches off from the Ganga at Nurpur (lower course of the Ganga). Bhagirathi River is one of the main rivers in Murshidabad district. Analyzing the image of the Bhagirathi River in Murshidabad district through the year 1970, 1977, 1990, 2000 and 2006, it is found that significant changed has been occurred in souththern part of the river and less change is...
