Question 5 Show the 10-yr, 15-min, constant-intensity design storm for a watershed in Baltimore. (Use NOAA Atlas 14 online website)

Which surface is likely to have the highest value of runoff detention storage? Group of answer choices a) A steeply sloped concrete parking lot b) A pitched roof c) A flat roof d) A glass tabletop

A rainfall hyetograph is provided for a 6-hour storm event, which occurred over a watershed with an area of 2100-acres (Ac). If the Phi-index is 0.71 in/hr, calculate the volume of runoff (VRO) from the storm (in Ac-ft). Report your answer to the nearest tenths (0.1) place. HINT...the answer should be around the 500-1,500 Ac-ft range (yes, it is a big range if you need to guess). Intensity (in/hr) 2.5 2.0 1.5 1.0 0.5 0.0 0 1 2 3 4 Time (hr) 5 6 7 2

In city X the storm drains are designed for a 25 year storm event. When determining the antecedent soil moisture what condition do you select: O AMC I O AMC II O AMC III O None of the above, since storm event does not have anything to do with AMC.

Please help and explain it don't just need the anawer
