The effect of pori hole distance variation on infiltration capacity in sandy clay soil sample drainage channels

Abstract

The infiltration capacity will decrease if the number of infiltration fields decreases. This results in increased surface runoff or inundation. The planning concept that creates a groundwater infiltration area in drainage will be able to reduce inundation in drainage. Pore Cylinder Hole is a water infiltration method by increasing water absorption in the soil. The aim of the study was to determine the effect of pore-hole spacing on infiltration capacity in pore-cylindrical drainage and to determine how much infiltration discharge due to variations in hole spacing using three levels of pore cylinder heights. This research was conducted using a pore-cylindrical drainage model and spacing the biopore holes and flowing water on the drainage surface. From the results of this study, it was found that the effect of the hole distance on the infiltration discharge, the closer the hole to the pore cylinder, the greater the infiltration discharge that occurs, it can be proven from the results of analysis of research data, for a flow rate of 400 cm3/sec, Qf = 35.1 cm3/sec. for spacing of holes 16 cm); Qf = 31.9cm3/s (to describe 32 cm holes); and Qf = 3.13cm3/s (for spacing of 16 cm holes).
