WM-12-06  aA thesis submitted in partial fulfillment of the requirements for the degree of Master of  Engineering in Water Engineering and Management  aThesis (M. Eng.) - Asian Institute of Technology, 2012  aVietnam has been significantly urbanized in recent years. The rapidly increasing of population  and expand of urban areas while low investment of drainage infrastructure lead to more  flooding occurs which has become in urban areas of Vietnam. The urban are requiring the  protective structures which can prevent or mitigate the occurrence of flood with the minimum  cost. That is the most survival important of development and urbanization in Vietnam.  The Intensity {u2013} Duration {u2013} Frequency (IDF) relationship of heavy rainfall is one of the most  important tools utilized by engineers for designing flood alleviation and drainage structures in  urban and urban areas. The establishment of such relationship was done as early. However,  such relationships have not been constructed in Viet Nam. There is a high need for  establishment of the IDF curves in Viet Nam.  Based on disaggregation technique and scale invariance properties of rainfall, this study used  daily rainfall data taken from Vietnam Institute of Meteorology and Hydrology (VNIMH) to  developed the IDF curves for seven stations which are located in whole the Red River Delta  of Vietnam. The scaling exponents were derived in all the analyzed stations. In the selected  test stations, the IDF curves based on scaling method show good result in comparison with  IDF curves obtained from short duration rainfall data.  The IDF relationships success derived from daily rainfall can be applied in drainage design in  the Monsoon areas in Vietnam with return period up to 10 years.  0aDrainagexVietnam 0aRain and rainfallzVietnam1 aClemente, Roberto S.,eChairperson0 aSutat Weesakul,eCo-chairperson1 aBabel, Mukand Singh,eExamination Committee1 aShrestha, Sangam,eExamination Committee2 aSwedish International Development Agency  (SIDA),eScholarship donor2 aAsian Institute of Technology.tThesis ;vno.
