Abstract
A comprehensive field monitoring and laboratory measurement of water quality of a river in Bangladesh was undertaken from January to April in 1995 and 1996. Subsequently, 1-D water quality model was developed, calibrated and verified with the collected data to quantify the state of pollution and the assimilative capacity of the river during the low flow period. The study indicates that the DO condition of the river water remains above the critical level of 4.0mg/L, supporting the survival of aquatic life including fish. The river still has significant assimilative capacity and can assimilate the waste load from future new industrial establishment without violating the DO standard.
