| Summary: | Weather and climate are related but different in time of changes and prediction. Weather consists of short-term variations such as precipitation air pressure temperature and humidity. Due to unpredictable changes, weather predictability is limited to days only. Our daily routine is affected by weather conditions; observation of weather conditions can help in understanding the activity. It is crucial to observe and study the weather changes in that particular area by using any of the invention that we have now. The changes and pattern of weather at Gambang and the local area can be studied by running an analyzation of hydrological data from Department of Irrigation and Drainage (DID). Rainfall distribution has for some time been researched by analyst to help with current innovations and engineering works. One of the investigations is to create RTP. There are a couple of approaches to create RTP, for example, utilizing Average Variability Method (AVM), Soil Conservation Services (SCS), Huff Time Method and Triangular Method. Based on this study objective, to establish Rainfall Temporal Pattern (RTP) for Universiti Malaysia Pahang, Gambang by using method of Huff Time Distribution Method (HTDM) and Water Resources Research Institute method (WRRI) to analyze the data collected. The data were observed and divided into two events which is for 60 minutes and 120 minutes rainfall event. From the data analysis, the summary of rainfall event happening around Universiti Malaysia Pahang was concluded. At station id of 3731018, name of JKR Gambang, there are 17 rainfall events that happening in 60 minutes time period, another 11 rainfall events happened in 120 minutes time period. A total of 28 precipitation events were recorded from year 2013 until 2018. Then, the observed data were divided into four equal quartile. The data were analyze according to each method and the result are in term of percentage. For the next study objective, the result from both method were compared. All of the four curve produce are represented each quartile which is first, second, third and fourth respectively. In order to compare the result from both methods, the difference are calculated in term of percentage are plotted. Rainfall Temporal Pattern are plotted by using Huff Time Distribution Method and Water Resources Research Institute method based on the analyzation of the data. The differences in each graph plotted varies from about 17.31% to 74.08%. |
