چکیده
Urban flooding is a major social and economic problem of any nation. The implication attributed to loss lives property, unwanted displacement emotional disturbance attached. While that the cost mitigation flood aftermath solution. Thus, storm water drainage part essential modern city infrastructure. need for proper analysis design drainages other road facilities cannot be overemphasized. To achieve this, critical available rainfall data, which key input, required. A 35 years daily data were obtained from NIMET, was carried out using frequency method. output generated are presented in graphical forms model. Ultimately, an IDF curve generated, depicts Abuja pattern 3-parameter model equation, I = 37Tr0.2 (t + 0.1)−0.9 formulated. This site or location specific. and/or formulated can adopted determine intensity if duration return period predictable.

Intensity-Duration-Frequency (IDF) rainfall curves, for data series and climate projection in African cities
Changes in the hydrologic cycle due to increase in greenhouse gases cause variations in intensity, duration, and frequency of precipitation events. Quantifying the potential effects of climate change and adapting to them is one way to reduce urban vulnerability. Since rainfall characteristics are often used to design water structures, reviewing and updating rainfall characteristics (i.e., Inten...
متن کاملConstruction of intensity-duration-frequency (IDF) curves for precipitation with annual maxima data in Rwanda, Central Africa
Detailed probabilistic information on the intensity of precipitation in Central Africa is highly needed in order to cope with the risk analysis of natural hazards. In the mountainous areas of Rwanda land slides frequently occur and might cause a heavy toll in human lives. The establishment of Intensity-Duration-Frequency curves for precipitation in Central Africa remains a difficult task as ade...
متن کاملDerivation of Intensity -Duration-Frequency -Area(IDFA) Curves for Mashhad City
A knowledge of rainfall distribution over a finite area is needed for small bydraulic structures design. Hydrologists have always been concerned about Depth- Area- Duration (DAD) for a specific storm in a watershed. An intense storm occurred on June 6, 1992 which claimed some lives in parts of Mashhad, Khorasan Province, Iran. Data of rainfall depth at 29 raingauge stations around the city and ...
