In the paper a quasi-analytical formula for moisture increase along the wetting front during infiltration into a soil column is presented. Based on the formula, the moisture distribution along the column of six soils available in the literature was calculated. Then their verification was carried out using empirical data and the results obtained from other type models. The impact on the front shape of such factors as recharge rate, initial moisture content and direction of seepage against the vertical was checked.
