Determination of Infiltration Rates on Marshall Silt Loam from Runoff and Rainfall Records1

Jose Bertoni, W. E. Larson and W. D. Shrader2

ABSTRACT

Using rainfall intensity and runoff rate measurements for plots with slope lengths of 36.3, 72.6 and 145.2 feet, infiltration rates were determined by the graphical method of Sharp and Holtan for 10 storms occurring during the years 1938 to 1942, inclusive. The plots on Marshall silt loam had been cropped to continuous corn since 1932. The average initial infiltration rate for all storms and all slope lengths was 0.79 inch per hour and the final infiltration rate was 0.21 inch per hour. The final infiltration rate varied with storms and slope lengths from 0.60 to 0.10 inch per hour. The average infiltration rate curve calculated from the mean of all curves for all storms and all slope lengths was expressed by the equation f = 0.211 + 1.019 e-0.056t. Final infiltration rate appears to increase up to June and July and then decrease rather sharply during August and September.
