Introduction to Infiltration

Q. A watershed 600 ha in area experienced a rainfall of uniform intensity of 2 cm/hr for a duration of 8 hours. If resulting surface runoff is $0.6M{m}^3$ , the average infiltration capacity is

1. $1.5cm/hr$
2. $0.75cm/hr$
3. $1.0cm/hr$
4. $2.0cm/hr$

Q. Intensity of rainfall at a place was found to be more than the infiltration capacity $\left(f_c\right)$ of the soil in that place. Then the actual infiltration $\left(f_a\right)$ will be

1. $f_a>f_c$
2. $f_a=f_c$
3. $f_a<f_c$
4. $f_a=0$

Q. Which of the following factors will influence the infiltration capacity of soil in a catchment?

1. Atmospheric Temperature
2. Rainfall intensity
3. Vegetation in the catchment
4. All of the above
