Question 4 of 10

4. A land is said to be water-logged when _______________

there is an accumulation of alkali salts in the root zone of the crop

there is a reduction in crop yield

there is salinity in the soil

Question 6 of 10

6. Which of the following statement is not correct about Einstein’s theory?

He put forward a mathematical approach to the problem of bed load transport

He introduced a factor called Einstein’s bedload function

He gave a curve graph which can be used to compute the bedload transport rate of a given channel

He further postulated probability of the grain being dislodged is directly proportional to the lift force which the flow can exert on the grain

Question 9 of 10

9. Which of the following statement is wrong about the requirement of good lining?

Brick tile lining may provide better abrasion resistance than cement concrete and boulder lining

The lining should be able to withstand the differential sub-soil pressure

Brick lining, concrete lining or precast slab lining can be easily repaired as compared to cast-in-situ concrete lining
