9. Lane's weighted creep theory assumes
10. An outlet is said to be proportional if its flexibility, 
11. In a syphon aqueduct
12. The ratio of the rate of change of discharge of an outlet to the rate of change in level of water surface in a distributary at its normal depth, is known as
13. Effective precipitation for a crop may be defined as
14. Lacey's equation for calculating flood discharge in rivers, is
15. A counter berm is
