1.Which method is used to make swimming pool water safe by eliminating harmful microorganisms, such as chlorine, ultraviolet light, or bromine?
2.Which of the following is least likely to be caused by calcium and magnesium salts?
3.What is the term for an open channel constructed on a canal bank, reinforced with stone pitching, designed to direct upland drainage water into the canal?
4.What is the name of the structure when the full supply level (FSL) of a canal is significantly higher than the drainage bed level, causing the canal to flow under siphoning conditions?
5.What is the name of the structure where the drainage water flows naturally by gravity because the drain's high flood level is well below the canal bed?
6.What is the term used for an outlet when the change rate of its discharge matches the change rate of the channel's discharge?
7.What is the term for a module or outlet where the discharge remains constant and restricted, regardless of changes in water levels within the distributary?
8.According to which theory is the total length of the impervious floor downstream of a hydraulic structure calculated?
9.In an inverted filter, the layers are arranged in order of increasing ____________ from the bottom layer to the top layer?
10.Why is an invented filter installed immediately beyond the edge of a concrete floor?
11.Which seepage theory, introduced by Khosla, is used in the design of hydraulic structures?
12.As per Mr. Khosla's observation, in which direction does the undermining caused by seepage begin?
13.Which parameter must be controlled to prevent undermining and ensure the safety of a hydraulic structure?
14.The reduction in head (H/L) is directly proportional to the creep length. What is the term used for the head loss per unit length of creep?
15.As per Blight's definition, the water that moves along the underside contour of a hydraulic structure travels a certain distance. What is this distance known as?
16.A hydraulic jump occurs downstream of the glacis toe to dissipate the excess energy of flowing water. The characteristics and intensity of this jump are determined by which dimensionless number?
17.What is the term for the sudden rise in water level downstream of a sloping glacis, occurring when a fast-moving shallow flow meets a slower-moving deeper flow, causing a disruption on the water surface?
18.What is the term used to describe the design scenario where a high flood flows over a weir causing elevated uplift pressures, but no water flows into the canals?
19.What is the name of the water control structure located at the beginning of a canal that regulates the flow from the main canal to its branch channel?
20.What is the term for the structures built along riverbanks to regulate the flow and safely direct water through hydraulic installations?
