An instantaneous unit hydrograph is a direct runoff hydrograph

Detailed Solution for Test: Hydrographs - 3 - Question 3

A finite unit hydrograph is indicated as the duration D → 0. The limiting case of a unit hydrograph of zero duration is known as Instantaneous Unit Hydrograph (IUH).

The shape of the recession limb of a hydrograph depends on
Detailed Solution for Test: Hydrographs - 3 - Question 4

The climatic factors control the rising iimb and the recession limb is independent of storm characteristics, being determined by catchment characteristics only.

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.
