Abstract

Intensity–Duration–Frequency (IDF) relationship of rainfall amounts is one of the mostCommonly used tools in
water resources engineering for planning, design and operation of waterResources projects. Historical rainfall records for
the most of towns and urban areas in India are available only from non–recording rain gauges .These are measurements of
daily/24 hours storm depths. The objective of this study is to derive IDF relationship of rainfall at central zone of Surat city
from daily/24 hours rainfall data. These relationships are useful inthe design of urban drainage works, e.g. storm sewers,
culverts and other hydraulic structures.Gumbel distribution and the Log Pearson Type III distribution (LPTIII) techniques
are commonly used to develop the IDF curve from rainfall data. In the present study Gumbel distribution method has been
used to derive IDF curve.
