title: [Research of moisture content variation in MSW landfill].
abstract: Using time domain reflectometry (TDR) technology, waste moisture content variation in aerobic and anaerobic landfill of MSW was monitored, in order to study its disciplinarian. The results showed that volume moisture content of waste increased with landfill time and water holding capacity of waste improved continuously. The correlation of water quantity and moisture content was positive in early aerobic landfill, but it became negative later. In anaerobic landfill, moisture content variation was caused by settlement and compression of MSW. TDR readings and waste material-based volume moisture content had a good correlation. The maximum error between them is about +/- 5% in aerobic landfill and +/- 2% in anaerobic landfill. TDR technology is applicable to measure moisture content in practical landfill engineering.
