IDF Values for Frequent Storms |

For design ARI 1, 3, 6 month and 1 year, the design rainfall is calculated using equation 13.5 (a), (b), (c) and (d):

$0.083_{I_{D}} = 0.4 x 2_{I_{D}}$ ……………………………Equation 13.5 (a)

$0.25_{I_{D}} = 0.5 x 2_{I_{D}}$ ……………………………..Equation 13.5 (b)

$0.5_{I_{D}} = 0.6 x 2_{I_{D}}$ ……………………………….Equation 13.5 (c)

$1_{I_{D}} = 0.8 x 2_{I_{D}}$ …………………………………..Equation 13.5 (d)

where,

$0.083_{I_{D}}$ , $0.25_{I_{D}}$ , $0.5_{I_{D}}$ and $1_{I_{D}}$ are required 1, 3, 6 month and 1-year ARI rainfall intensities for any duration D, and $2_{I_{D}}$ is the 2-year ARI rainfall intensity for same duration D, obtained from IDF curves.
