In Synder’s method of synthetic unit hydrograph development, basin lag is taken as
Detailed Solution for Test: Hydrographs - 3 - Question 6

The most important characteristic of a basin affecting a hydrograph due to a given storm is basin lag. Basin lag is the time difference between the centroids of the input (rainfall excess) and the output (surface runoff).

If a 4-hour unit hydrograph of a certain basin has a peak ordinate of 80 m3/s, the peak ordinate of a 2-hour unit hydrograph for the same basin will be
Detailed Solution for Test: Hydrographs - 3 - Question 8

With the reduction of unit hydrograph duration, 1 cm excess rainfall will occur in reduced period. So peak ordinate of UH will increase and time base will decrease. Thus the peak ordinate of 2 hr UH will be greater than 80 m3/s.

The point of inflection on the recession limb of a hydrograph represents
Detailed Solution for Test: Hydrographs - 3 - Question 9

The starting point of the recession limb, i.e., the point of inflection represents the condition of maximum storage.

A flood-hydrograph due to an isolated storm consists of
Detailed Solution for Test: Hydrographs - 3 - Question 10

The hydrograph is the response of a given catchment to a rainfall implicit. It consists of flow in all the three phases of runoff, viz. surface runoff, interflow and base flow.
