Water content and Strength of Dredged Soil (DS) obtained from Aliyar reservoir were measured after dewatering using Electro Osmosis (EO). The operational conditions adopted include electrode material (Cu, Fe, Al), voltage (6V, 12V, 24V) and duration (24 hours, 48 hours and 72 hours). 27 combinations of experiments were piloted to explore the influence of operational conditions on water content and strength in shear. Maximum reduction in water content was obtained in Fe electrode with 24V and 72 hours of duration for which the water content falls to 27.22% from 87% and the corresponding shear strength is 27.30 kPa. Further, the loss of electrode materials during EO process was also measured.
