| Summary: | IDF Curves, which is, stand for intensity - duration - frequency relationship is the standard for hydrologists in determining the rainfall intensity for any particular site or location. The study of IDF Curves was early carried out in the British Isles, where Lloyd- Davies (1906) was among the first to carry out an analysis of rainfall records for the purposes of stormwater drainage design. That was one of the earliest practiced carried out in developing the IDF Curves. So, on this study, Kota Kinabalu, which is, comprises 3-rainfall station has been selected as a study area. Kota Kinabalu has been selected as a study area because it is important to develop latest IDF Curves using the latest rainfall data instead of relying on the outdated IDF Curves available. Hence, the purposes of this study are to develop the IDF Curves for Kota Kinabalu in 2, 10, 20, 25 and 50 years of return period by using Method of Moment (MOM). As stated above, the method that will be used on this study is the Method of Moment (MOM). All the data of rainfall frequency (annually maximum rainfall depth) will be obtained from the DID Department of Kota Kinabalu. The range of the data obtained will be from the year of 1985 until 2004. At the final stage of this study, the IDF curve for Kota Kinabalu which comprises the 3 rainfall station of Inanam, Kiansam and Ulu Moyog will be developed, after the analysis process of all the rainfall data been done. This IDF curve will be useful for any hydrologic structure such as drainage system and so on. So, the necessity to develop the IDF Curves for Kota Kinabalu is important as a fact that Kota Kinabalu nowadays is moving towards rapid development and it may be as an early step to the development of other latest IDF Curves for others area in Sabah. |
