JEP – 1039

6. a) What is runoff and explain runoff estimation using SCS curve number model.

10

b) A 350 m long graded bund is to be designed for a cultivated land with sandy loam and a surface slope of 4%. The bund channel is to be formed by the embankment only. The horizontal distance between two bunds is 50.0 m. The 1 hour rainfall expected during the recurrence interval of 10 years is 10.0 cm/h. 10 7. a) Explain the methodology for identification of suitable sites for rainwater harvesting.

10

b) With neat figures explain check dams and farm ponds used for rainwater harvesting.
