Landscape Measures for Improved Management of Stormwater and Leachate at Old Closed Landfills
River re-opening strategies of piped streams are used to accommodate greater quantities of stormwater. However, experience in Norway has demonstrated challenges in applying standard principles of local infiltration and retention of water, when the former valleys have been used as dumping grounds. The water that come in contact with the waste can spread contaminants to adjacent areas. The aim of this investigation has been to collect experience on a selection of nationally and internationally transformation projects of landfills, where the landscape has been used as an active tool to deal with the complexity of the polluted masses in relation to stormwater.
