Abstract:
Assessing trends of hydrometeorological variables is necessary for climate change modeling, accurate water resources management and improved regional planning. This study investigated the seasonal, annual, maximum (max.) and mean rainfall trend using data from 1986 to 2013 collected from three selected gauge stations including Tarbela, Daggar and Saidu sharif. Similarly, the historic data (1986 to 2013) of flow of Brandu river and max. and minimum (min.) temperature of Tarbela and Saidu Sharif gauge station were analysed. To identify trends for the hydrometeorological parameters, both non-parametric and parametric (MK) tests were applied at 10% significant level. The study concludes, a mixture of increasing and decreasing trends. Annual max. rainfall exhibited an increasing trend in the study area. Similarly, total annual and mean annual rainfall for Daggar and Saidu Sharif gauge stations showed decreasing trend while Tarbela gauge station exhibited an increasing trend. Statistically significant trends were found for annual total rainfall.
