Following are some of the multiple choice questions on the Docks and Harbor Engineering with answers that will help the students in developing their knowledge.

The first and the last soundings and every tenth soundings are fixed by angular observations

The intermediate soundings are fixed by the time intervals

All the above.

17. If h and h1 are the heights of a light house and the observer in a ship in metres above M S L then the horizontal distance from the ship to the light house in kilometres is

23. The horizontal angles from the boat between A and B and B and C, the stations on the shore are respectively θ1 and θ2. The distances AB = L1 and BC = L2. For calculating the angle α2 at C between the boat and station B is obtained by using the following formula: where (β is horizontal angle between A and C at B).

ships get shelter and protection against destructive forces due to sea waves

facilities are provided for receiving cargo and passengers

port buildings are constructed for commercial purposes

all the above.

28. P and Q are two stations on the shore line at distance d. If the angle between Q and the boat O and P is a and the angle between P and Q at boat O is β, the x and y. Coordinate along PQ and perpendicular to PQ from O are :
