Abstract:

Five empirical infiltration equations were evaluated using data from blocked infiltrometer tests with wetted perimeter values ranging from 28 to 49 cm. The results indicate that the Kostiakov cumulative infiltration equation modified to include wetted perimeter raised to a power, appeared to satisfactorily represent the effect of wetted perimeter on infiltration in furrows.
