    TREND ANALYSIS OF EVAPORATION AND SOLAR RADIATION USING INNOVATIVE TREND ANALYSIS METHOD
    (university of el oued/جامعة الوادي, 2021-05-01) Ahmed, M.O; Ogedengbe, K
    Analysis of trends in monthly evaporation and solar radiation in the face of climate change gives useful information for better planning and management of water resources. This paper examines the monthly evaporation and solar radiation trend using the recently developed innovative trend analysis method (ITAM). The monthly evaporation trend result shown that 75% of the months indicated decreasing trend with the month of February, March, August and April decreased significant at 0.1%, 10%, 10% and 5% significance level respectively. As regards solar radiation all the months indicated decreasing trend with January, July and October shown a decreasing trend at 5% significant level. By comparing the Mann-Kendall method with the ITAM the reliability of ITAM was ascertained. Hence, ITAM can be effectively utilized in climate change scenarios where useful information is needed for accurate management and planning of water resources.
