Question: Lost Creek's 1 -hr unit hydrograph at the Chamberlain Avenue crossing is shown in the following table. Determine the expected flow rate in the creek

Lost Creek's 1 -hr unit hydrograph at the Chamberlain Avenue crossing is shown in the following table. Determine the expected flow rate in the creek at that location if a 2-hr storm produces 2.0 cm of rain in the first hour and 2.5 cm of rain in the second hour. Assume losses to rainfall are constant at 0.5 cm/hr and base flow is constant at 5 m3/sec.

Time (hrs) 0.0 0.5 1.0 15 2.0 25 3.0 3.5 4.0 45 me 10 30 70 120 100 70 40 20 0 m/seC
