Short Duration Storm Computation

 
 

 

For short duration of less than 30 minutes in MSMA (2000), the design rainfall depth Pd is given by:

 

 

 

where

 and  are the 30 min and 60 min rainfall depths, respectively, obtained from the published polynomial curves.

 is the adjustment factor for storm duration based on Table 1.1 (Table 13.3) and Figure 1.1 (Figure 13.3).

Table 1.1 is applicable to East and West Coast of Peninsular Malaysia. For East Malaysia, the values of  for East Coast are used.
