1.When water evaporates from the surface of paddy fields, it rises into the atmosphere as water vapor. How does this water vapor exist in the air?
2.What is the term for the pressure exerted by air when it is completely saturated with the water vapors it contains?
3.What term describes the quantity of water vapor in the air expressed as the weight of moisture per unit volume?
4.Clouds form through the process of condensation and are made up of tiny ice crystals and water droplets. What is the approximate diameter, in microns, of these water droplets?
5.What term describes the ratio, expressed as a percentage, of the area actually irrigated within a year to the total culturable commanded area of a channel or outlet?
6.Hydraulic structures are engineered to safely manage floodwaters. What is the term for floods that match the design flood magnitude over the project's expected lifespan?
7.What is the term used for a flood that can happen in a basin under the most extreme meteorological and hydrological scenarios?
8.What term describes a river or stream that is accumulating sediment and forming dunes within its channel?
9.What is the name of the triangular landform created when a river splits into several smaller streams before flowing into the ocean?
10.What is the term for a river whose floodwaters evaporate or disappear before reaching the sea or another river?
11.What is the term for the extension of stone pitching beyond the toe of a riverbank slope to protect it from scour?
12.What is the term for a groyne that extends upstream, facing the flow direction?
13.What is the term for a continuous weir flood structure with dividing piers designed as reinforced elements, where the weight of the piers prevents uplift forces?
14.What term describes the increase in river water level upstream caused by building a weir?
15.Through which structure should water free of silt be delivered into the canals?
16.What is the name of the masonry or concrete wall built perpendicular to the weir's axis to separate the main weir from the under sluices?
17.What is the typical range of flow velocity in a fish ladder designed to reduce flow energy and allow downstream fish to swim upstream easily?
18.During severe floods, a wall is constructed from the pond level up to the high flood level along the entire length of the regulator. This wall rests on piers and resists water pressure through its own weight. What is this type of wall called?
19.What are the structures called that are built on the riverbed upstream of a head regulator to ensure only clear water enters the canal?
20.In a hydraulic jump, the water depth prior to the jump is termed the initial depth. What is the name given to the water depth following the jump?
