**Park in Malir river-bed

**Mr Nayyar Iqbal Raza (Park in Malir river-bed, Feb 13) desires to convert the dry river-bed of the Malir river into a man-made forest. He has also reminded us that Karachi Nazim Naimatullah Khan had indicated about a year back that he intended to convert the dry river-bed of the Malir river into a lively park.

The Malir river is, in fact, a hill torrent. Beyond the bridge on the Superhighway across it, it divides into two forks. Each fork has a very steep bed slope. A hill torrent brings flash floods when there is heavy rain in the catchment.

In 1977 the Malir river brought down a super flood with very high velocity which washed away everything which was in the river-bed and also inflicted heavy damage on the population along the river, as well as some damage to Drigh Road PAF base.

Again, in 1978 a similar flood but of lesser intensity was brought down by the river. In 1977, more than 300 persons were washed away one afternoon. The flood was caused by heavy downpour in the upper catchment of the river.

At the time when it was raining in the Malir upper catchment, there was sunshine in Karachi and nobody suspected that such a heavy flood would come down the river. People were taken by surprise and more than 300 persons were washed away and lost their lives. Properties worth millions of rupees were damaged. Oil drums of the refinery were seen floating in the sea.

The Sindh government assigned Wapda to plan flood control scheme for Karachi. Wapda prepared a comprehensive plan, which consisted of three components, namely two dams in the upper catchment, channelling of the Malir river and construction of bypass channel to avoid flooding of populated areas.

Work was carried out by the KDA. Only channelling part of the river was done. The study carried out by Wapda showed that 25,000 to 30,000 cfs flood passed on that fateful afternoon.

An unobstructed bed width of about 2,700 ft. was required to pass this flood safely. Since the bed was encroached upon at several places, the flood stage increased, severely damaging properties around it. It was also concluded that the Malir river has a wet cycle of about 25 to 30 years.

In view of what has been studied and learnt in the past I would like to warn every person concerned with the development of the Malir river that it is very dangerous to play with nature.

The Malir river-bed should not be encroached upon, otherwise floodwater would find different routes to flow down to the sea. Damage in that case would be colossal.

The cargo handlers should have a check on heroin that is imported from Afghanistan - our policy makers are taking great advantage of the low prices.
