Climate Change and Water Resources in South Asia by M. Monirul Qader Mirza, Q.K Ahmad

By M. Monirul Qader Mirza, Q.K Ahmad

This booklet addresses the main urgent water source concerns in South Asia, really when it comes to weather switch and variability. this can be a area characterized by way of ample water through the monsoon, while devastating floods take place, and by means of shortage of water and droughts through the dry interval. those severe occasions usually reason huge harm to infrastructure, estate, livestock and human populations. Agriculture and different key monetary sectors endure drastically in the course of those occasions. the result of weather and hydrologic types point out elevated vulnerability until sufficient model measures are designed and implemented.  Such guidelines have to depend on a framework that comes with lively participation of the stakeholders.

The life of the Kaptai Reservoir in Bangladesh was estimated to be 300 years, but today it is calculated at only 186 years (Mirza, 1986). The Kulekhani reservoir, which had a life expectancy of 100 years, lost 1 million m3 of its gross storage capacity in just 12 years after its impoundment, which began in 1981. The reservoir had a designed storage of 12 million m3. 8 million m3 of sediment into the reservoir (Nippon Koei, 1994). The specific sediment yield of this torrent was 38,000 m3/km2, but the siltation rate assumed in the design of the reservoir was just 700 m3/km2/year (JICA, 1974).
