Abstract/ Executive Summary:

Collected field data of BWDB were studied to analyze the morphological parameters of the river Padma for a reach length of I05 kilometers from the confluence at Gualundo to the Confluence near Chandpur, Due to non-availability of a complete set of data for every year from 1956 to 1977. the analysis was based on the available data set for the years 1967 , 1969 and 1977 only. Hence the findings may be limited to the period from 1967 to 1977 with approximate accuracy. However. it was found that the sinuosity of the reach was gradually decreasing. the bed slopes were getting steeper. the channels were becoming wider and shallower. the thalweg meander shapes, ML/MB were increasing and the thalweg meander size. WB/W were decreasing indicating that 'the river had a tendency to develop braiding.

Start Date: 00-00-1967

End Date: 00-00-1977

Program Area: Knowledge Management

Commodity: Water management

Objectives:

To study the characteristics of morphological parameters of the river Padma from Goalundo to Chandpur.

Methodology:

A complete set of data only for the years 1967, 1969 and 1977 were available for the present study. The base data for the analysis were of 1956. A course map of the river Padrna, for the year 1956, the cross-sections of the river from the confluence of the Ganges Brahmaputra at Goalundo to the confluence of the Padma-Megbna were collected from the Directorate of River Morphology Research and Training of Bangladesh Water Development Board, Dhaka. These data were superimposed on the course map and analyzed to find out the different relations such as thalweg sinuosity, channel shape, meander shape and thalweg meander size.
