An experimental study on infiltration of film-furrow irrigation

Abstract

Abstract: Film-furrow irrigation is a combination of techniques of film-mulching irrigation and furrow irrigation. Film with infiltration holes is covered in furrows and irrigation water flow on it and infiltrate to soil. The relations between cumulative infiltration and wetted depth and infiltration time are investigated in this paper. An infiltration tester for film-furrow irrigation is developed, an experiment with 2-row and 3-column holes is conducted, and cumulative infiltration and wetted depth at deferent time are observed. The results show that the relation between cumulative infiltration and infiltration time can be fitted with the Kostiakov-Lewis model, the relation between wetted depth and infiltration time can be fitted with a power function; therefore infiltration of film-furrow irrigation can be described with these two models.
