The catchment area of the river Gumti is in India's hilly Tripura state. The area of the catchment area is 4,900 kilometers. And, the recorded rainfall is 2,800 millimeter. Gumti was the only one outlet of the catchment area. To reduce the pressure on the Gumti river, the Government of Pakistan made the men made 'Salda'river about 30 kilometer north of the Comilla district from the eastern border of Pakistan (now Bangladesh) in 1960. It was somewhat helpful, but due to the increasing amount of monsoon rainfall in the upper catchment area had caused the erosion of the southern embankment in 1998 and caused heavy damages to the crops and fish culturing ponds. The author surveyed the flooding area in 1998 and found that Government's negligence was one of the main causes of southern bank erosion. The erosion could have been protected by the authority should a proper step would have been taken before the erosion in Parura village, 15 kilometer west of Comilla city.
