Runoff and time

Ground water flow and time

Rainfall and time

Solution:

The probability that s 50 years flood may NOT occur at all during 25 years life of a project (round off to two decimal places), is_____.

Solution:

If the subsoil is permeable, water percolates deep down to meet the groundwater. This type of flow is known as:

Surface runoff

Subsurface runoff

Baseflow

Interflow

Solution:

Which of the following types of rain gauges is incorrect?

Tipping bucket type rain gauge

Weighing bucket type rain gauge

Simon's rain gauge

Natural siphon's type of rain gauge

Solution:

If Qs4 and Qs6 are the equilibrium discharges of S-curve for the catchment obtained by 4-hour unit hydrograph (UH) summation and 6-hour UH summation, respectively, then the ratio Qs4/Qs6 is ____.

1.5

3.2

1.44

Solution:

A study of the isopluvial maps revealed that a maximum rainfall depth of 200mm in 12 hours has a return period of 50 years. The probability of a 12-hour rainfall equal to or greater than 200mm occurring at that place once in 30 years is:

0.46

0.6

0.56

Solution:

An isolated 3-h rainfall event on a small catchment produces a hydrograph peak and point of inflection on the falling limb of the hydrograph at 7 hours and 8.5 hours respectively, after the start of the rainfall. Assuming no losses and no base flow contribution, the time of concentration (in hours) for this catchment is approximately

8.5

7.0

6.5

5.5

Solution:

A lined irrigation canal with trapezoidal cross section and curved corners has a 5 m bed width, 2.5 m depth, and 1.5(H):1(V) side slope. The longitudinal bed slope of the canal is 1 in 1000 and Manning's n = 0.016. If the crop has a 150 mm field irrigation requirement in a 10-day KOR period, then the area of land the canal can irrigate is _______ km2.
