Abstract

The importance of precise future projections of precipitation trends cannot be over-looked in water resources
management and socio-economic development of any country. In this study, the bias-corrected output (future projections
of precipitation) of two Regional Climate Models (RCMs), CCAM and RCA4 is plotted against the observed historic
precipitation data (1970-2000) for Mangla basin to evaluate the annual precipitation trends in near and far future i.e.
(2011-2040, 2041-2070 and 2071-2100) under both RCP 4.5 and 8.5. Comparison of the results indicate that there
would be more precipitation (increasing trend) in mid period (2041-2070), and significant decrease is noticed for the last
period (2071-2100) of the ongoing century. Consequently, due to the changing trends in climate variables and land use
practices the basin may face extreme events in future. To cope with such alarming situation proper pro-active strategies
and planning is essential.
