#Kor-watering:-
The first watering given to the crop when it has grown a few centimeters is called Kor-Watering of Crops

The Optimum depth of kor-watering is:-
1)19 cm for Rice,
2)13.5 cm for Wheat and
3)16.5 cm for Sugarcane.

Paleo (Paleva):-
The first watering before sowing the crop is called Paleo.

Base Period:-
Time Between First And Last Watering

Crop Period:- Time Between Sowing and Harvesting of Crop.

Reservoir Capacity for a given Demand is obtained from Mass Inflow Curve

Clover Leaf Cofferdam Belongs to Cellular Type

Shape of Phreatic Line is Parabolic

Garret's diagram is used in the Design of a Canal

Head Loss through the Siphon Barrels is Calculated by,
Unwin's Formula...Unwin's Formula is generally used to Calculate the Afflux

Canal Escapes serve as a Purpose of 'Safety Valve'

Aqueduct(It's like Bridge):-
Canal over a Natural Drain

Super Passage:-
Natural Drain over the Canal

Level Crossing:-
Natural Drain and Canal at Same level.

Syphon Aqueduct:-
Constructed where the H.F.L of Natural Drain is Higher than the Canal Bed

Defective Air Circulation in
Plant's root zone is an Effect of Water Logging

Water Logging means when the Capillary fringe Reaches the Root Zone of Plants

🌟Elementary Profile of a Dam is a Right angled Triangle

Lacey's Concept of Design of Canals is Based on the Unlined Channels only

The Canal which is aligned along a Ridge Line is called as Watershed Canal

The Canal which is aligned at Right Angled to the Contour is called as Side-Slope Canal
