Question 1

Assertion A: Basin walls have to be of much greater height than dock walls. Reason R: Tidal basins are subject to fluctuations of levels due to tidal variations Select your answer based on the coding system given below:
A)Both A and R is true and R is the correct explanation of A
B)Both A and R is true but R is not correct explanation of A
C)A is true but R is false
D)A is false but R is true

Accepted Answer

Basin walls need to be higher than dock walls because tidal basins experience level changes due to tides, which is correctly explained by the reason.

Question 2

Pick up the correct statement from the following:
A)A harbour without any port complex, is called a refuge harbour
B)A harbour used for fishery, is called fishery harbour
C)The terminal building of a commercial harbour consists of an administrative block, customs clearance and ware-houses
D)All the above

Accepted Answer

All the statements provided are correct. A refuge harbour is indeed a harbour without a port complex, primarily used for shelter. A fishery harbour is used for fishing activities and related purposes. The terminal building of a commercial harbour typically includes administrative offices, customs clearance facilities, and warehouses for storage.

Question 3

Which of the following structures protects the shore by trapping of littoral drift?
A)Groynes
B)Sea walls
C)Revetments
D)Moles

Accepted Answer

Groynes are structures built perpendicular to the shoreline, primarily designed to trap littoral drift (the sediment moved along the coast by the action of waves and currents) and thus protect the shore by preventing beach erosion and aiding in beach nourishment.

Question 4

The minimum diameter of turning besin, where ships turn by going ahead and without tug assistance should be (L is the length of the ship)
A)L
B)1.5 L
C)2.0 L
D)4.0 L

Accepted Answer

The answer of The minimum diameter of turning besin, where...

A)The maritime structures should be designed to withstand wave motion of air
B)The wind vortex results in conical depression in the air surface
C)A tube of air rotating at hundreds of kilometres per hour forms a tornado
D)all of the above

Accepted Answer
