Establishment of Intensity-Duration-Frequency Curves for Precipitation in the Monsoon Area of Vietnam
Le MINH NHAT*, Yasuto TACHIKAWA, and Kaoru TAKARA
*Graduate school of Urban and Environment Engineering, Kyoto University Synopsis The rainfall Intensity-Duration-Frequency (IDF) relationship is one of the most commonly used tools in water resources engineering, either for planning, designing and operating of water resource projects, or for various engineering projects against floods. The establishment of such relationships was done as early as in 1932 (Bernard). Since then, many sets of relationships have been constructed for several parts of the globe. However, such map with rainfall intensity contours has not been constructed in many developing countries, including Vietnam. There is a high need for IDF curves in the monsoon region of Vietnam. This research is to construct IDF curves for seven stations in the monsoon area of Vietnam and to propose a generalized IDF formula using base rainfall depth, and base return period for Red River Delta (RRD) of Vietnam. Keywords: Rainfall intensity, Design rainfall, Intensity-Duration-Frequency relationship (IDF), Vietnam.

Introduction
The rainfall Intensity-Duration-Frequency (IDF) relationship is one of the most commonly used tools in water resources engineering, either for planning, designing and operating of water resource projects, or for various engineering projects against floods. The establishment of such relationships was done as early as in 1932 (Bernard, 1932). Since then, many sets of relationships have been constructed for several parts of the globe. However, such map with rainfall intensity contours has not been constructed in many developing countries, including Vietnam. There is a high need for IDF curves in the monsoon region of Vietnam but unfortunately the adequate long historical data sets are frequently not available. A rainfall intensity-duration-frequency (IDF) relationship is commonly required for designing of the water resource projects. There has considerable
