- Flash floods in the eastern and northern rivers are characterized by a sharp rise followed by a relatively rapid recession, often causing high flow velocities that damage crops and property.
- Local floods due to high localized rainfall of long duration in the monsoon season often generate water volumes in excess of the local drainage capacity, causing localized floods due to drainage congestion.
- Monsoon floods from the major rivers generally rise slowly and the period of rise and fall may extend from 10 to 20 days or more. Spilling through distributaries and over the banks of the major rivers causes the most extensive flood damage, particularly when the three major rivers rise simultaneously.
- Floods due to storm surges in the coastal areas of Bangladesh, which are generated by tropical cyclone, cause extensive damage to life and property. These cyclones are predominant during the post-monsoon (October and November) and pre-monsoon (April to June) period.

Famous quotes containing the word categories:
“All cultural change reduces itself to a difference of categories. All revolutions, whether in the sciences or world history, occur merely because spirit has changed its categories in order to understand and examine what belongs to it, in order to possess and grasp itself in a truer, deeper, more intimate and unified manner.”
—Georg Wilhelm Friedrich Hegel (1770–1831)
“Of course I’m a black writer.... I’m not just a black writer, but categories like black writer, woman writer and Latin American writer aren’t marginal anymore. We have to acknowledge that the thing we call “literature” is more pluralistic now, just as society ought to be. The melting pot never worked. We ought to be able to accept on equal terms everybody from the Hassidim to Walter Lippmann, from the Rastafarians to Ralph Bunche.”
—Toni Morrison (b. 1931)
“The analogy between the mind and a computer fails for many reasons. The brain is constructed by principles that assure diversity and degeneracy. Unlike a computer, it has no replicative memory. It is historical and value driven. It forms categories by internal criteria and by constraints acting at many scales, not by means of a syntactically constructed program. The world with which the brain interacts is not unequivocally made up of classical categories.”
—Gerald M. Edelman (b. 1928)
