With the increasingly severe shortage of agricultural water resources and the problem of land salinization, finding effective irrigation methods to improve soil conditions has become particularly important. The aim of this study was to investigate the effects of initial soil salinity on the infiltration characteristics of film hole irrigation. In this work, indoor soil box infiltration experiments were conducted to study the c...

Film hole irrigation is a new type of film‐mulched irrigation technology. To investigate the influences of five factors—bulk density, initial soil water content, irrigation depth, film hole diameter and infiltration time—on the infiltration characteristics of film hole irrigation, 12 experiments were conducted. The infiltration characteristics considered were the cumulative infiltration ( I ), infiltration rate ( i ) and avera...

Soil infiltration is characterized by scale dependence, so the accuracy and reliability of indirect methods used to estimate soil infiltration properties from available soil physical data are often below expectations. This study aimed to determine the scale‐dependent relationship between soil infiltration and soil physical properties and to establish pedotransfer functions (PTFs) for estimating normalization factors ( F C ). F...

Based on the volume balance (VB) equation, the surface water profile was shown to be a power function and Philip equation equal to the Kostiakov–Lewis equation when the infiltration parameter a = 0.5. With this assumption, an equation was proposed for estimating infiltration parameters together with Manning roughness. The method requires only multi‐point water advance data of border irrigation. Solving the equation requires us...
