Title : Permeability Falling Head and Shape Factors of Recharge Wells for Artificial Recharge

Abstract :

TThere are several variables that determine in the process of impregnation include the flow of water into the well, the value of shape factors and in situ field permeability.This research aim is to investigate the shape factor of flat base recharge wells values of the three models whose upper walls are made of concrete buis with diameters of 0.6 m, 0.8 m, and 1.0 m.The high porous wall with var iations: 0.3 m, 0.7 m and 1.0 m. The shape factor is the coefficient of dimension planning which takes into accou nt the perimeter and area of the recharge well, volume and water level. The Permeability coefficient is very important. Experiments in the field are three recharges well models in a flat base impregnation on the porous wall (L) test and well radius (R The value of permeability of soil obtained by direct drilling of the research area in Sukolilo Village, Malang Indonesia. Field permeability was obtained by using auger boring falling Head method with a soil depth of 00.0 m to 2.65 m.he result showed that shap e fa ctor simultaneously influenced the high of porous wall (F = 23.71 > F table = 5.32; P < 0.05). However, the positive correlation between the changes of shape factor and high of porous wall in flat base on the recharge wells (R2 = 0.88)
