An annual flood series contains 100 years of flood data. For a return period of 200 years the Gumbel's reduced variate can be taken as ________
A sediment reservoir is planned for a 2100 sq.m site that has a peak inflow of 120cumec. The runoff from a 4cm rainfall is 2.04cm and the outlet structure has a peak capacity of 50cumec. What is the storage volume needed to handle this storm (in cumec) ? Take ratio of Storage to runoff volume as 0.386
