Important 1 Liners from Irrigation Engineering
Few of the Important 1 Liners from the subject Irrigation Engineering
Irrigation Engineering - 1 liners
Kor-watering
- Kor-Watering of Crops refers to the first watering provided to a crop after it has grown a few centimeters.
- The ideal depth for kor-watering,
- For Rice - 19cm
- For Wheat - 13.5cm
- For Sugarcane - 16.5cm
Paleo (Paleva)
- Paleo, also known as Paleva, is the first watering before planting the crop.
Base Period
- The interval between the first and last waterings
Crop Period
- Time elapsed between crop sowing and harvesting.
Aqueduct (like a bridge)
- A canal that spans a natural drain.
Super Passage
- Natural Drainage Across the Canal
Level Crossing
- Both the natural drain and the canal are on the same level.
Syphon Aqueduct
- Built where the H.F.L of natural drainage is greater than the H.F.L of the canal bed
Other 1 Liners
- The Mass Inflow Curve is used to calculate reservoir capacity for a given demand.
- Clover Leaf Cofferdam Is a Cellular Type
- The Phreatic Line has a parabolic form.
- Garret's diagram is utilized in the Canal Design.
- Unwin's Formula is used to calculate head loss through syphon barrels... The Afflux is often calculated using Unwin's Formula.
- Canal Escapes provide the function of a 'Safety Valve.'
- Waterlogging causes poor air circulation in the root zone of plants.
- Waterlogging occurs when the capillary fringe of plants reaches the root zone.
- A dam's basic profile is a right-angled triangle.
- Lacey's Canal Design Concept is based only on unlined channels.
- Watershed Canal refers to a canal that runs along a ridgeline.
- Side-Slope Canal refers to a canal that is positioned at a right angle to the contour.
