Irrigation Engineering The field capacity of a soil is 25%, its permanent wilting point is 15% and specific dry unity weight is 1.5. If the depth of root zone of a crop, is 80 cm, the storage capacity of the soil, is 8 cm 12 cm 10 cm 14 cm 8 cm 12 cm 10 cm 14 cm ANSWER DOWNLOAD EXAMIANS APP
Irrigation Engineering When a canal flowing under pressure is carried below a natural drainage such that its F.S.L. doesnot touch the underside of the supporting structure, the structure so provided, is called Syphon Syphon-aqueduct Aqueduct Super passage Syphon Syphon-aqueduct Aqueduct Super passage ANSWER DOWNLOAD EXAMIANS APP
Irrigation Engineering While deciding the alignment of a proposed canal taking off from a river at B, three alignments of approximately equal lengths are available. These cross a drainages at C1, C2 and C3 where drainage bed levels C1 > C2 > C3, you will provide at site C3 An aqueduct A super passage A syphon aqueduct A syphon An aqueduct A super passage A syphon aqueduct A syphon ANSWER DOWNLOAD EXAMIANS APP
