- A. Silting & scouring
- B. Meandering
- C. Aggrading
- D. Degrading
Explanation: This alternating erosion of the concave bank and deposition on the convex bank causes a river to develop bends known as meanders.
Correct answer: Meandering- A. Virgin
- B. Tidal
- C. Flashy
- D. Deltaic
Explanation: A flashy river responds rapidly to storm rainfall, producing a sudden rise and fall in flood discharge.
Correct answer: Flashy- A. Aggrading river
- B. Degrading river
- C. Deltaic River
- D. Stable river
Explanation: A stable river maintains its channel alignment, slope and overall regime without significant long-term change.
Correct answer: Stable river- A. Area Assessed
- B. Area leased
- C. Area irrigated
- D. Area cultivated
Explanation: The area actually irrigated during a year and charged according to the applicable water rates is the area assessed.
Correct answer: Area Assessed1145. The floods which exceeds the designed magnitude of a reservoir is called _______________________?
- A. High floods
- B. Standard protects flood
- C. Intensive flood
- D. Storm flood
Explanation: A standard project flood is the design flood associated with the reservoir project, and a flood exceeding that design magnitude is…
Correct answer: Standard protects flood- A. Base flow
- B. Peak runoff
- C. Storm runoff
- D. Unit duration
Explanation: A unit hydrograph represents direct runoff from one unit of effective rainfall occurring over a catchment for a specified duration, called…
Correct answer: Unit duration- A. H = v2/2g
- B. H = v/g
- C. H = v2 / g2
- D. H = v2 / g
Explanation: A Pitot tube converts velocity head into pressure head according to Bernoulli’s relation, h = v²/2g.
Correct answer: H = v2/2g- A. Absolute Humidity
- B. Relative Humidity
- C. Low humidity
- D. High Humidity
Explanation: Relative humidity is the ratio of the actual vapour pressure to the saturation vapour pressure at the same temperature, usually expressed…
Correct answer: Relative Humidity- A. Saturation vapour pressure
- B. Actual vapour pressure
- C. Saturation deficit
- D. Partial pressure
Explanation: Saturation deficit is calculated as saturation vapour pressure minus actual vapour pressure at the same temperature.
Correct answer: Saturation deficit- A. All are correct
- B. Saturation pressure
- C. Vapour pressure
- D. Partial pressure
Explanation: Partial pressure is the pressure exerted by one component of a gas mixture, such as water vapour in the atmosphere.
Correct answer: Partial pressure- A. Horton
- B. Darcy
- C. Lacy
- D. Kennedy
Explanation: Horton represented infiltration capacity as a curve that decreases rapidly after rainfall begins and then approaches a nearly constant…
Correct answer: Horton- A. Surface runoff
- B. True surface runoff
- C. Base flow
- D. Sub-surface runoff
Explanation: Water that travels directly over the land surface and reaches a stream quickly is termed true surface runoff.
Correct answer: True surface runoff- A. Develop
- B. Rehabilitate
- C. Remodel
- D. Manage
Explanation: Hydrology supplies the information needed to manage water resources by understanding their recharge, movement, storage, and depletion.
Correct answer: Manage- A. Compound curve
- B. Composite curve
- C. Double curve
- D. All are correct
Explanation: A compound curve is made from two or more circular arcs of different radii bending in the same direction and joined by a common tangent.
Correct answer: Compound curve1155. That point in a body at which it will balance if loaded or supported is called ____________________?
- A. Centre of pressure
- B. Centre of gravity
- C. Centre of mass
- D. Mass centre
Explanation: The centre of gravity is the point through which the body's weight acts, so the body balances when supported at that point.
Correct answer: Centre of gravity- A. Mass curve
- B. Volume curve
- C. Capacity curve
- D. All are correct
Explanation: A capacity curve relates the water level of a reservoir or tank to the volume of water stored at that level.
Correct answer: Capacity curve- A. Dry weather flow
- B. Municipal flow
- C. Waste water flow
- D. Surface flow
Explanation: Dry-weather flow is the flow present in a drain during periods without rainfall or irrigation runoff, consisting mainly of sanitary sewage…
Correct answer: Dry weather flow- A. E2 - E1
- B. E2 / E1
- C. E1 - E2
- D. E1 / E2
Explanation: Hydraulic-jump efficiency is the ratio of energy remaining after the jump to energy before it, E2/E1.
Correct answer: E2 / E1- A. Far from
- B. Below
- C. Within
- D. Near
Explanation: Waterlogging occurs when the water table rises within the root zone, filling soil pores and restricting air available to roots.
Correct answer: Within- A. D0.67
- B. D0.65
- C. D0.66
- D. D0.64
Explanation: Kennedy's silt theory gives critical velocity as proportional to D^0.64, where D is the flow depth.
Correct answer: D0.64
