Abstract: Hydraulic conductivity is one of the most important factors controlling water‐table depth in subsurface drained agricultural land. The current design procedure is to calculate lateral drain spacing using some average of ...

Abstract: Hydraulic conductivity is an important parameter in the design of subsurface drainage systems. Hydraulic conductivity from field investigations in alluvial soils shows a high spatial variability. The objective of this study ...

Abstract: Crop yield is a function of many agroclimatic factors. However, excessive wetness, dryness, or soluble salts in the root zone are three important stresses that inhibit crop growth and reduce yield. Stress due to wetness ...
