Abstract :

Background and Objective: Artificial recharge of groundwaterthrough floodwater spreading is an approved method for improvement of groundwater resources. The appearance of sowbug to floodwater spreading system of Gareh Baygon Plain has been changed physic-chemical properties of soil. The main objective of this research is to evaluate soil infiltration rate with activity of sowbugs. Method:This study has been conducted in Kowsar aquifer management of Gareh Bygone plain. One of the floodwater spreading systems named Bisheh Zard1 was selected. This system has 6 sedimentation basins. The second sedimentation basin was chosen and divided to 11 plots. Infiltrability of 11 paired plots was determined utilizing the double ring method. Findings: Results showed that the appearance of sowbug that make hols with 7 milimeter and average one meter depth improve the soil physical properties and enhance the infiltration rate about 7.2 centimetres per hours and showed a significant difference at the 1 % level. The burrowing macro fauna, including the sowbug, form channels that facilitate accelerated flow of water towards the aquifer. Discussion and Conculation: This study approved that sowbug has a great effect on infiltration water to crusted soil that occurs by floodwater spreading. Sowbugs burrows have a marked effect on surface infiltration of water through the soil. The present research state that sowbug can be as useful agent for controlling of crusted soil from fine clay in sedimentation basinsform channels that facilitate accelerated flow of water towards the aquifer and increase the life time of floodwater spreading systems after 30 years and Gareh Bygone Plain desert has been changed to a evergreen forest.
