How does vegetative surface type affect amount of runoff

(1) Meteorological/Climate factor: -Rainfall intensity -Rainfall amount -Rainfall duration -Distribution of rainfall over the drainage basin. (2) Phsyiographic factors (e.g. watershed) - watershed size -Watershed shape -watershed slope (3) Vegetation - Dense vegetation leads to less run-off while sparse vegetation leads to more run-off. (4) Urban development. - Roads and buildings have do not allow infiltration into the soil. Water will therefore run off directly into the stream, at a very fast rate and in significant volume.

Answer:

9.9 years

step-by-step explanation:

a = p(1 + rt) . . account balance after time t at rate r starting with principal p

3000 = 2500(1 + 0.0202t) . . filling in the given numbers

1.2 = 1 + 0.0202t . . divide by 2500

0.2 = 0.0202t . . . subtract 1

0.2/0.0202 = t ≈ 9.901

it will take about 9.9 years for the account balance to reach $3000.
