In drip irrigation, water is applied near the plant root through emitters or drippers, on or below the soil surface , at a low rate varying from 2 – 20 litres per hour. Water flowing in the furrow into the soil spreads laterally to Parallel earth bunds or levees are provided in order to guide the advancing sheet of water. the location and relative elevation of the water source.

The International Commission on Irrigation and Drainage is dedicated to enhancing the worldwide supply of food and fibre for all people by improving water and land management and the productivity of irrigated and drained lands through appropriate management of water, environment and application of irrigation, drainage and flood management techniques. It is impossible to get completely uniform distribution of water around a sprinkler head and spacing of the heads must be planned to overlap spray areas so that distribution is essentially uniform. Subsurface irrigation is again divided into natural sub-irrigation and artificial sub-irrigation. Overhead or Sprinkler Irrigation: In this method an attempt is made to simulate natural rainfall. Material and Methods . Varied quantities of water are allowed on the fields at different times. The method is one of the most recent developments in irrigation.
Sprinkler Irrigation
Sprinkling is the method of applying water to the soil surface in the form of a spray which is somewhat similar to rain. Merits & Demerits of Irrigation | Irrigation Types with Neat Sketches | Irrigation Questions/Answers. Gotthard Base Tunnel (Rail Tunnel) Design Engineering, Construction & Cost, Structural & Non Structural Defects in Building Construction, SAP 2000 and ETABS Training Course on Realworld Civil Engineering Projects. Where the land grade is less than 1% in the direction of furrow, striate graded furrows may be adapted. Flow rates are related to the infiltration to the rate of the soil. By using a low supply rate, deep percolation or surface runoff and erosion can be minimized. The irrigation system for a field or a farm must be compatible with the other existing farm operations, such as land preparation, cultivation, and harvest. Gravity irrigation methods are less expensive, but requires power and water lines and other obstructions. It minimizes the loss of water by deep percolation below the root zone or by evaporation from the soil surface. Water flowing in the furrow into the soil spreads laterally to irrigate the area between furrows. Under closed conduit- there are two types of irrigation. Very low delivery rates may also result in fairly high evaporation from the spray and the wetted vegetation. This method also requires People mostly need deluge when there is drought or no rain. Surface irrigation systems are usually classed as either flood or furrow systems. It involves slow and frequent application of water to the plant root zone and enables the application of water and fertilizer at optimum rates to the root system.
