Identifying rainfall trends in highly urbanized area is extremely important for various planning and implementation activities, including designing, maintaining and controlling of water distribution networks and sewer networks and mitigating flood damages.
However, different available methods in trend analysis may produce comparable and contrasting results.
Therefore, this paper presents an attempt in comparing some of the trend analysis methods using one of the highly urbanized areas in Sri Lanka, Colombo.
Recorded rainfall data for 10 gauging stations for 30 years were tested using the MannKendall test, Sen’s slope estimator, Spearman’s rho test, and innovative graphical method.
Results showcased comparable findings among three trend identification methods.
Even though the graphical method is easier, it is advised to use it with a proper statistical method due to its identification difficulties when the data scatter has some outliers.
Nevertheless, it was found herein that Colombo is under a downward rainfall trend in the month of July where the area receives its major rainfall events.
In addition, the area has several upward rainfall trends over the minor seasons and in the annual scale.
Therefore, the water management activities in the area have to be revisited for a sustainable use of water resources.
