| Summary: | In the study of the design rainfall, the information on rainfall duration, average
rainfall intensity and temporal rainfall pattern is important. This project is to develop
of temporal rainfall pattern for Sarawak since temporal pattern for Sarawak is still
not available Hydrological Procedure No. 1 (HP-No.1). Urban Stormwater
Management Manual for Malaysia (MASMA) had developed the temporal pattern
for design storms in Peninsular Malaysia and the temporal rainfall pattern for East
Coast of Peninsular Malaysia were adopted for Sarawak. Temporal rainfall pattern is
important in flood estimation which is useful in engineering practice such as design
of hydrologic structures, flood plain management, river ecology studies and flood
insurance studies. As mentioned in MASMA, the recommended technique by the
Australian Rainfall and Runoff (AR&R) known as the ‘Method of Average
Variability’ and method in Hydrological Procedure No.1-1982 are used to develop
temporal rainfall patterns. 5 minutes rainfall data from year 1998 to year 2006 for 10
selected rainfall stations in Sarawak is obtained from Department of Irrigation and
Drainage (DID) Sarawak to conduct this project. The temporal rainfall patterns
developed are for 10 minutes,15 minutes, 30 minutes, 60 minutes, 120 minutes, 180
minutes and 360 minutes duration. After obtaining the temporal rainfall patterns, the
patterns are to be compared to the patterns for East Coast of Peninsular Malaysia. It
is expected that the design temporal rainfall pattern obtained can contribute to
Sarawak hydrological research. |
