Title

ASSESSMENT OF VARIATIONS OF THREE INFILTRATION MODELS FOR FURROW IRRIGATION

Pages

  53-62

Abstract

 Soil INFILTRATION rate is the most important factor in designing irrigation systems. Therefore, selection of a suitable INFILTRATION equation is a prerequisite for achieving the best performance of any irrigation system. As a plant's performance integrates numerous factors, particularly water demand in arid environments, providing adequate and timely water in irrigated fields passes a challenge. In this regard, the coefficients of three popular INFILTRATION equations, namely: KOSTIAKOV-LEWIS, PHILIP AND SCS, were investigated along the VOLUME BALANCE equation. The cumulative INFILTRATION depths in furrows planted with sweat com were also compared using ' different equations. Three periods: first, mid and end of maize growth season were considered in this study. Results indicated that the application of Philip equation (one point method) was not applicable because it over-predicted the INFILTRATION depths. Moreover, the mean absolute error (AAE) of the Philip equation (0.00683) and SCS equation (0.00373) were larger than that of the KOSTIAKOV-LEWIS equation (0.00253). Finally, the results revealed that the KOSTIAKOV-LEWIS equation were the best predictor of the three INFILTRATION equations used in this study.
