Measuring the Water Balance of Various Multilayered Covering Systems on the Waste Tip Georgswerder (Hamburg, FRG)

Along with the remediation activities on the waste disposal site Georgswerder in Hamburg a research and development program with regard to the water balance of several multilayered surface sealing systems is being carried out. For this purpose six large-scale test fields with a size of 500 m2 each were installed in the landfill surface sealing, which was set up in 1987. They serve to carry out a long-term observation of the Georgswerder cover and other systems which differ from it. The tests are supported by the BMFT and the City of Hamburg and focus on the comparative evaluation of the effectiveness of the different covering systems. The objective is to derive general suggestions with regard to the design and dimensioning of surface sealing systems and to develop technically uncomplicated controlling device to supervise their effectiveness.
