Refer to Example 11.4 to answer the following questions qualitatively.
(a) Would you expect the stream flows measured in the watershed to change if the 12.3 cm of precipitation fell in a 6-hr instead of 24-hr period? If so, how?
(b) Why might groundwater contribution to stream flow increase after a storm event?
(c) Why is the sum of the flows in the direct runoff column multiplied by 6 hours when obtaining the runoff volume?
(d) Would the unit hydrograph change if the stream flows were measured in 3-hr instead of 6-hr increments but the 6-hr values did not change?
