A stream of 160 litres per second was diverted from a canal and 120 litres per second were delivered to the field. An area of 1.5 hectares was irrigated in 9 hours. The effective depth of root zone was 1.7 m. the runoff loss in the field was 420 cumec. The depth of water penetration varied linearly from 1.7 m at the head end of the field to 1.1 m at the tail end. Available moisture holding capacity of the soil is 24 cm per metre depth of soil. It is required to determine the water conveyance efficiency, water application efficiency, water storage efficiency, and water distribution efficiency. Irrigation was started at a moisture extraction level of 45% of the available moisture. A= 8646

Storm Sewers and Detention

The storm drains system transports rainwater or stormwater and other runoff from roads, parking lots, and roof downpipes directly to nearby creeks, rivers, or the sea without any treatment.
