In the rise and fall method of reducing levels, the arithmetic check is:
सही उत्तर: घ) ΣBS − ΣFS = ΣRise − ΣFall = Last RL − First RL
In the rise and fall method all three quantities must agree, which also checks intermediate sights.

A simple circular curve has a radius of 200 m and a deflection angle of 90°. Its length is about:
सही उत्तर: ग) 314.2 m
Length of curve = πRΔ/180 = π × 200 × 90/180 = 100π ≈ 314.2 m.

For a simple circular curve of radius R and deflection angle Δ, the tangent length is:
सही उत्तर: ख) R tan(Δ/2)
Tangent length T = R tan(Δ/2); 2R sin(Δ/2) is the long chord and R(1 − cos(Δ/2)) the mid-ordinate.

In plane table surveying, finding the position of the instrument station on the sheet by sighting three well-defined points already plotted is called the:
सही उत्तर: क) Three-point problem (resection)
The three-point problem is a resection method that locates the occupied station from three known plotted points.

The soil moisture content held after free drainage of gravity water has practically ceased is called the:
सही उत्तर: ग) Field capacity
Field capacity is the water retained against gravity; available water for plants lies between field capacity and wilting point.

A cross-drainage work in which a natural drain passes OVER an irrigation canal is called a:
सही उत्तर: ख) Super-passage
In a super-passage the drain is carried above the canal; in an aqueduct the canal is carried over the drain.

In Lacey's regime theory, the silt factor f is related to the mean particle diameter mr (in mm) by:
सही उत्तर: क) f = 1.76√mr
Lacey's silt factor is f = 1.76√mr, where mr is the mean diameter of bed particles in millimetres.

Bligh's creep theory is used in the design of:
सही उत्तर: घ) Weirs on permeable foundations against piping
Bligh's theory assumes that seepage water creeps along the base contour of a weir; the creep length must be enough to prevent piping.

In run-of-river hydropower projects in Nepal, the structure after the intake that removes suspended sediment before water enters the headrace or penstock is the:
सही उत्तर: ग) Desanding (settling) basin
A desander slows the flow so that sediment settles out, protecting turbines from abrasion by the heavy silt loads of Himalayan rivers.
