SEASONAL VARIATION OF HYDRAULIC PARAMETERS AND THEIR INFLUENCE UPON SURFACE IRRIGATION APPLICATION EFFICIENCY

摘要

A field investigation was made to observe and character¬ize the seasonal hydraulic behavior of an irrigated farm unit. Subsequent analyses indicated that near equal lev¬els of application efficiency are attainable over a wide range of conditions. The relative influences of intake rate, border length, slope, roughness, and soil moisture deficit on application efficiency are demonstrated.
