Abstract
This research was conducted to study the extreme rainfall intensity-duration-frequency (IDF) relationship, covering return periods from 2 to 100 years.
This paper presents an analysis of rainfall data from Sistan and Balochistan, for durations from 15 min up to 12 h.
The results are compared to analysis by others of data from other countries, which serves to highlight an anomaly in the longer duration results.
The shorter duration results are still considered plausible and potentially useful, pending more detailed analysis of longer data sets.
The statistical analysis of shorter duration rainfall data indicates considerable flood-alleviation purposes to that particular study area.
The floods in Balochistan showed conclusively that flood hazard in the area poses a large and yet-untamed problem for both the regulatory body (public) and the local authorities.
With increased development in the flood-plain the economic implications are likely to grow significantly regarding a number of issues paramount in the area of Sistan and Balochistan.
