Question 3
A unit hydrograph for a watershed is triangular in shape with base period of 20 hours. The area of the watershed is 500 ha. What is the peak discharge in m3/hours?
Question 4
The rainfall on five successive days on a catchment was 3, 6, 9, 5 and 1 cm respectively. If the φ-index for the storm can be assumed to be 3 cm/day, the total direct runoff from the catchment due to this storm is
Question 5
The surface joining the static levels in several non- pumping wells penetrating a continuous confined aquifer represents
Question 6
Which one of the following is not a major type of strom precipitation?
Question 7
A watershed got transformed from rural to urban over a period of time. The effect of urbanization on storm runoff hydrograph from the watershed is to
Question 8
A hydraulic jump occurs in a rectangular, horizontal, frictionless channel. What would be the pre-jump depth if the discharge per unit width 2m3/s/m and the energy loss is 1 m ?
Question 9
A hydraulic jump is formed in a 2 m wide rectangular channel which is horizontal and frictionless. The post–jump depth and velocity arte 0.8 m and 1 m/s, respectively. The pre–jump velocity is __________ m/s. (use g = 10 m/s2).
Question 10
A channel with a mild slope is followed by a horizontal channel and then by a steep channel. What gradually varied flow profiles will occur?
