For border strip method of irrigation, determine the time required to irrigate a strip of land of 0.06 ha in area from a tubewell with a discharge of 0.025 m³/s. The infiltration capacity of soil may be taken as 5 cm/hr and average depth of flow in the field is 8 cm. Also, determine the maximum area that can be irrigated by this tubewell.

A stream of 200 lps was diverted from the river and 150 lps were delivered to the field. An area of 3 hectares was irrigated in 8 hours. The root-zone depth was 1.8 m. The run-off averaged 50 lps for 3 hours. The depth of water penetration varied linearly from 1.8 m at a head of the field to 1.2 m at the end of the field. Determine the water-conveyance efficiency, the water-application efficiency, the water storage efficiency, and the water distribution efficiency.

(b) A catchment consists of an asphalt pavement that drains into a rectangular concrete channel. The asphalt surface has an average slope of 0.6%, and the distance from the catchment boundary to the drain is 50 m. The drainage channel is 30 m long, 25 cm wide, 20 cm deep, and has a slope of 0.8%. For an effective rainfall rate of 60 mm/h, the flow rate in the channel is estimated to be 0.025 m³/s. Estimate the time of concentration, te of the catchment. Hint: Use the Manning's in the kinematic wave equation form.
For border strip method of irrigation 0.04 ha area is irrigated from tubewell with a discharge of 0.02 cumec. The infiltration capacity of soil may be taken as 5cm/h and the average depth of flow on the field as 10 cm. The time required to irrigate a strip of land of area 0.04 ha will be

Q: Determine the area which can be irrigated using surface method of irrigation with a source of water having a discharge of 10000 litres per minute. The available moisture holding capacity of the soil is 180mm per metre and depth of root zone is 1.Im. Irrigation is done when 40% of available moisture is used. The total losses during irigation are 35% and peak daily moisture use is 4.5mm.
