The concept of the one‐dimensional intercept in a one‐dimensional infiltration experiment is reexamined. It is found that the intercept can be interpreted in terms of saturated conductivity and sorptivity as long as infiltration is not taking place under ponded conditions and as long as the air entry value is zero. The first condition will often be difficult to realize in practice, and the second difficult to assess under field conditions. Thus the linear intercept is of theoretical rather than practical interest.
