Question

Use the following info where applicable: 1 acre = 43, 560 ft^2; 1 hectare = 10,000 m^2; 1 foot = 12 in; 1 m = 100 cm T or F Comparatively, urbanization (development) has a greater effect concentrated shape of a watershed than the elongated one. T or F The watershed shape affects timing and peak flow of runoff to the outlet. T or F The time to peak, t_p = T_R - D/2; where T_R is the time to rise and D is the duration of the rainfall. T or F Unit hydrograph is assumed to represent the response of a watershed to a unit (1 in.) rainfall for a particular duration which could be different from 1 hr. T or F In general, the larger the watershed area the greater the surface runoff, the greater the overland flow rate, and the greater the stream flow rate.

Explanation / Answer

16.True. For a watershed that is elongated in shape the time to reach the peak runoff is more compared to the Concentrated shaped watershed. Urbanisation results in decreasing the time to peak runoff in a concentrated shape.

17.True. Elongated shape catchments have more timing to peak runoff . Concentrated shape catchments have less time to peak runoff.

18.True

19.True

20. True.
