determine volume of infilterated water from river whit Invention Permeate _ Case Study: Rivers jaban

The relationship between surface and ground waters and their impact on each other is very important. The aim of this study was to determine the exchange of water between River jaban and Damavand aquifer. Invention Permeate, measuring the water exchange between river and aquifer was built and is being used in this study for the first time. Invention permeate was the ability of measureing the actual rate of infiltration from the river bed. This device can be used on a local scale and rivers which have low flow. Four stations to measuring the infilteration rate from the bed jaban River. Among station, station 1, in the upstream,has the lowest infiltration rate which it could be attributed to te loe permeat of shale and dense limestone below the river bed. Station 3 has the largest water infilteration water due to the high depth to water table. The resolts show that the discharge of jaban river to the aquifer is about 495 L/S .
