Abstract

The attempt was made for estimating reference evapotranspiration for and Harnai and Wakawali station and also the trends of different meteorological parameters were also studied. The study observed that the reference evapotranspiration for Harnai station was nearly constant, while for Wakawali station it was decreasing by -12.22 mm. The trend of different meteorological parameters showed that for Harnai and Wakawali station annual mean temperature was increasing trend was by 0.008°C and 0.044°C respectively. For Harnai station mean relative humidity was decreasing at the rate of -0.07% per annum and for wakawali station was decreasing at the rate of -0.033% per annum. Average annual wind speed for Harnai station was decreasing by -0.029 km/hr and for Wakawali station was also decreasing by of -0.15 km/hr.It is concluded that reference evapotranspiration for Harnai station was nearly constant throughout the year.
