Chowdhury, Rezaul Kabir and Alam, Md. J. B. and Das, P. and Alam, Md. A. (2007) Short duration rainfall estimation of Sylhet: IMD and USWB method. Journal of the Indian Water Works Association, 39 (4). pp. 285-292. ISSN 0970-275X
Abstract
Bangladesh has scarcity of short duration rainfall data. An attempt has been undertaken to estimate short duration rainfall of Sylhet city using daily rainfall data of period 1970-2002. 1-hour maximum rainfalls have been estimated from the yearly 24-hour maximum data using Indian Meteorological Department (IMD) empirical reduction formula. USWB depth duration ratios have been used to estimate 5 min, 10 min, 15 min, 30 min and 120 min rainfall depths. Extreme Value Type-I distribution has been used for analysis of 1-hour maximum rainfall. It has been found that IMD formula can be effectively used in Sylhet city.
